GENERAL
The assembly and manufacturing instructions in this manual are
for use in conjunction with the manufacturers components
identified by Catalog numbers listed under the two types of
drives covered by this manual on pages 15 and 16.
Although the supplied components are designed to conform
with the requirements of CMAA 70, Specification for Top Running
Bridge & Gantry Type Multiple Girder Electric Overhead Traveling
Cranes and ANSI B30.2, Safety Standard for Overhead and
Gantry Cranes, it is the installers responsibility to assure that the
finished crane assembly complies in total with all applicable
local, state and national codes and standards including those
mentioned herein. On a hand powered crane with an electric
hoist, a fused safety disconnect switch should be provided and
mounted on the bridge near the main collectors. Crane wiring
should be done by a licensed electrician and be in accordance
with the National Electric Code (ANSI/NFPA 70).
RUNWAYS: Runway beams on which these cranes will
operate must be amply strong to support crane bridge,
hoisting equipment, and rated load. Runway rails must be
level and parallel within ±1/8”. Rail joints must be smooth
and held firmly in alignment either by bolted splice bars or
welding. Rails should be securely fastened to runway beam.
MATERIAL TO BE PURCHASED LOCALLY
TO COMPLETE A CRANE BRIDGE
STRUCTURAL STEEL: All structural steel should be first quality, free from rust and excessive mill scale, and conform to
ASTM A 36 Standard Specification for Structural Steel.
For the drawing identifying all dimensions, material sizes, location of cross shafting, brackets, etc.; refer to the following chart:
The crane bridges described in this manual are intended for
normal indoor service. Bridges to be used for outdoor or unusual
service require special consideration.
This manual illustrates specific configurations for the range of
coverage shown, specifically from 10 foot thru 60 foot spans and
up to and including 25 tonne capacity. Minor deviations to the
configurations shown (such as shaft bearing spacing, shaft
lengths, etc.) may be made providing that any changes and/or
alterations to those shown, be performed only by a properly
qualified person. The manufacturer accepts no responsibility for
any altered bridge configurations.
Material listed by catalog numbers on pages 15 and 16 are
applicable only to crane configurations outlined in this manual,
specifically limited to a maximum rated load of 25 tonnes and a
maximum span of 60 feet.
Cataloged end trucks listed on page 15 will accommodate rail
sizes from 25# thru 85#.

BRIDGE BEAMS: For each rated load, span and type of bridge
select bridge beam size from the tables shown on pages 17 thru
28.
The beam which is selected to be used for the bridge girder must
be straight with flanges parallel to each other and flanges 90
degrees to the web. See Figure 1 below.
NOTICE
A. All of the tables used in selection of structural steel beams
have been produced by our engineering department using well
established design guides for this type of crane bridge. IT IS
IMPORTANT THAT ALL INSTRUCTIONS BE FOLLOWED AND
THAT RECOMMENDED COMPONENT APPLICATION LIMITS
NOT BE EXCEEDED.
B. Assembly of beam and channel requires welding. IT IS
EXTREMELY IMPORTANT TO THE SAFETY OF THIS BRIDGE
THAT THIS WELDING BE DONE BY A COMPETENT WELL
TRAINED WELDER. It is our strong recommendation that the
welder used in this construction be qualified as prescribed by
the American Welding Society (AWS) Specification for Welding
Industrial and Mill Cranes D14.1 - latest issue.

Figure 1.
11953
Refer to Figure 2. Place channel on supports as shown in Step
I. The beam is sighted for camber and placed with camber in
direction shown in Step II. Weld one end of the channel to the
beam. Clamp, with “C” clamps, the channel to the beam flange.
Provide sufficient “C” clamps so as to hold the channel in contact
with the beam.
12725C
Figure 2.
3
Weld in accordance with the weld information given, starting at
one end, staggering the weld from side to side, proceeding to
the opposite end of the channel without interruption. It is
important to stagger the weld from side to side in order to retain
beam straightness. After welding, draw a taut string from end to
end of beam as shown. Beam should either be parallel to string
or have some camber. Camber should not exceed 1/888 of
span.
WARNING
Trolley stops (clip angles) must be installed on both
ends of the bridge beam to prevent hoist trolley from
running off the end of the beam, which could result in
injury to the operator and others and damage to the
load and other property.
ASSEMBLING BRIDGE GIRDER TO END TRUCKS
FABRICATION OF GIRDER FOR BRIDGE
BEAM WITH VERTICAL PLATE
Refer to Figure 3. Place beam on supports as shown in Step I.
The beam is sighted for camber and placed with camber in
direction shown in Step II. Place plate vertically against the
flanges of the girder and tack weld the plate in place.
Weld in accordance with the weld information given, starting at
one end of the girder, staggering the weld on top and bottom of
the girder, proceeding to the opposite end of the girder without
interruption. After welding, draw a taut string from end to end of
beam as shown. Beam should either be parallel to string or have
some camber. Camber should not exceed 1/888 of span.
CROSS SHAFTS: For hand geared cranes, cross shafts are
required. The cross shafts are to be of AISI 1018 cold drawn
steel, with standard mill tolerance of +.000”, -.002”. For shaft
diameter and lengths, refer to Figure 10, Hand Geared Bridge
Assembly. The builder must check that the cross shaft couplings
clear cross shaft bearings.
1. Refer to Figure 4-Bridge "Whale's Tail" Bolted End Connection,
Figure 4B-Bolt Plated End Connection and Figure 5-Bridge
Welded End Connection. Figure 4 shows a girder end connection
that may be optionally purchased as a kit. Figure 4B shows
optional bolted plate girder connection that may be purchased.
Figure 5 is an end connection that may be fabricated by the
crane builder. Make the notch to the dimensions shown with a
1/2" radius at the intersection of the cuts with a cutting torch and
smooth the burned area by grinding. Support beam about two
feet from each end on a pair of horses, or other suitable support
(adjustable, with clamping ability is preferred). Place beam on
supports so that camber side is at top. In case of beams with
capping channels the channel side is up. For beams with
vertical plates the plates are to the outside of the crane (away
from the centerline).
When setting up the beams on supports, make certain that the
top flanges at the trucks are level as shown in Figure 6.

2. Locate end trucks in the notch of the girders, one at each end
of the girders. Make certain trucks are level with each other and
are level at the four points as shown in Figure 6.
It is quite possible that the bottom flange of the girder is not level
even though the top flange is level. DO NOT LEVEL FROM
ROUGH TRUCK STRUCTURE. Correct operation of the hoisttrolley requires that the top flanges are level.
3. To check the distance between the trucks, push all truck
wheels toward the center of the span. The distance from the
outside of the wheel on one side of the span to the inside of the
wheel on the other side of the span should equal the span length
for the 8” and 10” diameter wheels. See Figure 7. The tolerance
on this distance is +1/32”.
12983
Figure 7.
12847B2
Figure 6.
4. For Squaring Crane there are measuring dimples available on
the inside faces of the truck above the axles. To check the
squareness, use a spring scale on the end of a steel tape and
measure diagonally across the crane. Then measure across the
opposite diagonal with the same force on the scale. These
dimensions should be within 1/16” of each other.
Any other method of squaring the trucks that gives comparable
results may be used.
After squaring the trucks double check the span at both ends of
the trucks.
5. After assuring that the trucks are accurately positioned and
squared, complete girder connections and then proceed to
instructions for assembly for the type of crane being built. The
girder connections are shown in Figures 4, 4B and 5.
6. For the bolted end connection, first clamp the horizontal
gusset plate (Ref. No. 3) to the top of the truck so that the center
of the holes is in line with the center of the trucks.
8
Do not use excessive heat or weld that might cause distortion.
Alternate welds as much as possible. Weld the angles (Ref. No.
5), long leg horizontal, to the web of the girder and to the gusset
plate. Next, place the rings (Ref. No. 1) in the holes on the gusset
plates and weld to the top of the truck. Place the cap (Ref. No.
2) on the inner ring and hold in place with a couple of bolts. Bolt
the connection (Ref. Nos. 2, 7 and 8).
7. Position the angle (Ref. No. 4), short leg, against the side of
the truck and weld in place. Using the angle as a template drill
three 1/2" diameter holes in the web of the girder and bolt up
(Ref. Nos 6, 8 and 9).
8. For the welded end connection weld the angles (Ref. No. 3),
long leg horizontal, to the truck and to the girder web. Position
the angle (Ref. No. 2), short leg, against the side of the truck and
weld in place to the truck and to the girder web. Weld the brace
(Ref. No. 1) in place. All welded connections must have this
brace.

as outlined on Pages 4 and 8.
4. The gear case (with wheel pinion), motor and brake are
shipped as an assembly. Bolt this assembly to the side of the
truck with four socket head cap screws with lockwashers. Install
vent plug in place of pipe plug at top of gear case.
5. The electrical enclosure and fused disconnect switch is to be
mounted where required by the crane builder. Assure all
clearances.
6. Add rails as shown on Figure 9.
7. Locate and weld trolley stops at the ends of the girders as
shown on Figure 11. Bumpers must engage trolley stops.
INSTRUCTIONS FOR ASSEMBLING
A HAND GEARED CRANE BRIDGE
1. Refer to Figure 10, Hand Geared Bridge Assembly.
2. Prepare bridge girder with capping channel or vertical plate,
if required (See Pages 3 and 4).
3. Follow instructions for assembling bridge girder to end trucks
as outlined on Pages 4 and 8.
4. Mount and bolt the hand geared drive adapter for the cross
shaft to the side of the truck with four socket head cap screws
with lockwashers.
5. Locate and tack cross shaft support angles to the girder.
Recheck that angles are level and square and finish welding
according to Figure 11.
6. Form pillow block supports by mounting the angles together
as shown in Section C-C of Figure 11. Mount the pillow blocks
to the completed assembly by bolting.
7. Place the proper number of pillow blocks and couplings on
each shaft section. Notice that the separate bearing locking
collar has a counterbore on one side. This counterbore fits over
the protruding inner race of the pillow block bearing. Place
locking collar on the shaft properly.
8. Place the hand chain wheel and guide on the appropriate
shaft section (near the center of the crane) within 12” of a
bearing support. For cranes 10 tonnes and more, a keyway
5/16” x 5/32” needs to be cut into the cross shaft location at the
hand chain wheel. Put key in place.
9. Set shafting in place, align pillow blocks to cross shaft support
angles and clamp in place.
12
10. Check horizontal and vertical alignment of the cross shaft by
using a taut line. Complete assembly when alignment is assured.
11. Set space between cross shafts to 1/8”. Position couplings
and drill 3/8” diameter holes through the shaft and coupling
using the holes in the coupling as a guide. The coupling has a
pre-drilled hole through one side only. The shaft and coupling
are then secured by hex head bolts with lockwashers and nuts.
12. Slide bearing locking collars into place next to pillow blocks.
Make sure that the counterbore in the collar is fitted over the
extended race of the bearing. Fasten to shaft with set screw in
locking collar.
13. Add rails as shown on Figure 10.
14. Locate and weld trolley stops at the ends of the girders as
shown on Figure 11.
PAINTING
After all welding is completed and prior to installing the cross
conductors, wire brush all steel and remove all scale, weld
splatter, flux and any other foreign matter. Grease spots are to
be cleaned using commercially available solvent. Wash with
clear water an area six inches either side of all welds to remove
flux residue.
The electrical panel must be closed, and areas such as the
switch handle, Off-On identification, wheel gear and pinion, and
nameplate, etc., must be masked prior to painting.
Any national brand zinc-rich, chromate primer may be used and
applied according to the manufacturer’s directions. Final coat is
recommended to be high gloss enamel, especially suited for
steel surfaces and as recommended by any national brand paint
manufacturer. Application must be in accordance with
manufacturer’s recommendations.
MARKINGS
Codes require that the capacity of the bridge be shown on both
sides of the crane, legible from the floor. Normal practice for
marking is to use capacity in tons. For example: 1 TON, 2 TON,
etc. Stencil forms are readily available that may be used with
brush on or spray-can paint. Commercially available block
letters and numerals with adhesive backing could also be used.
Selection of size should be such that the sign can be easily read
from the operating floor.
The builder’s name shall also be placed on the crane in a
prominent location along with a serial number or other means of
crane identification.
NOTICE
The crane builder and user are responsible for marking
the crane and also to check for compliance with all
local, state and national codes.
12980
Figure 12. Main Collector Assembly
PUSH BUTTON SYSTEM
The preferred way of operating the controllers on the crane from
the floor is a festooned system sold as a kit. This is to be installed
as shown in the literature supplied with this system.
CROSS CONDUCTOR SYSTEM
A cross conductor system is a means of providing electric
current from the main conductors to the moving hoist-trolley.
The preferred cross conductor system is a festooned system
sold as a kit and it is to be installed as shown in the literature
supplied with this system.
WARNING
Ordinarily the crane is grounded to the runway beam
through the contact with the crane wheels. Certain
environments may prevent proper grounding by this
means. In those cases, a 4th runway conductor and
collector should be provided to assure adequate
grounding.
This also applies to the cross conductors and the
electrical contact between the trolley wheels and the
bridge girder.
INSTALLATION OF THE CRANE BRIDGE
MAIN COLLECTOR ASSEMBLY
Refer to Figure 12, Main Collector Assembly.
The collectors listed (Catalog Numbers 931077, 931078, 931080
and 931099) are compatible with and will operate only on
conductor bars listed as Catalog Numbers for Crane Runways
on page 15. The builder must check to ensure that the proper
spacing and location of the conductors will clear all obstructions
in the building.
Installation of the crane on the runway shall be performed only
by a qualified crane installer. For information regarding attaching
and lifting or moving the loads during installation, refer to ANSI
B30.2 - latest edition, Chapter 2-3 and other applicable codes.
WARNING
Before installing the crane on the runway, lock the
runway conductor disconnect switch in the open (off)
position.
13
Prior to the start of any crane erection the building should be
measured for spans of rails and clearances. These
measurements should be checked against the corresponding
crane measurements to insure correctness of “fit”. After
assurances that the crane fits the building, determine orientation
of the crane position with respect to the runway.
Before crane operation the vent plug must be in the proper
location in the gear case. The vent plug replaces the pipe plug
in the highest location on the end of the gear case. See Part No.
113533-82, Operating Instructions and Parts List, Bridge Drive
Gear Case, included with this package.
BRAKE
These types of cranes are usually lifted into position on the
runway rails in one piece.
Immediately after the crane is placed on the runway rails check
wheel flange clearances to the rail. Clearance between side of
rail head and inside flange of wheel will vary from 3/8” to 1-1/8”
depending on the wheel and rail combination and whether or not
the truck is centered on the rail. Total wheel float will not be less
than the 3/4" recommended by CMAA Specification #70.
NOTE: It is suggested that the trolley and hoist be
installed on the crane bridge at this time so that all
wiring connections can be completed.
A separate piece of literature in the literature package covers
parts and adjustment of the brake.
OPERATION
Prior to placing the crane into service, OSHA requires that the
user perform and record certain tests including proof loading the
crane. Refer to ANSI B30.2-latest edition for information
concerning these requirements.
