Brief description
Hydraulic spreaders are specially designed rescue equipment for spreading, squeezing
and pulling. They are used for rescuing trapped or enclosed accident victims.
Driven by a hydraulic power unit it is possible to open doors, lift vehicles and other moveable
loads, push away and move vehicle parts and loads and crush tubes and pillars with the
The speed of movement of the spreader arms is controlled by the greater or lesser degree of
force applied to the pushbutton on the handle. The maximum spreading force is only applied
when the pushbutton is fully depressed.

Hydraulic supply
Power units and pumps
Only WEBER-HYDRAULIK power units and hand pumps may be used to drive the spreader.
Equipment from other manufacturers can only be used under certain conditions.
Therefore always consult with us before operating a device with a power unit from another
Before using pumps and power units from other manufacturers always
contact WEBER-HYDRAULIK or an authorised dealer.
Incorrect application can lead to hazardous situations for which we cannot
accept any liability!
The connection of the device with the power unit is carried out via high pressure hoses.
Hoses are available in lengths of 5 m, 10 m, 15 m and 20 m. As the length of the lines
increases so too does the associated pressure loss. With a line length of 50 metres this
pressure loss remains acceptable and has no significant effect.
Do not use damaged hoses!
With damaged hoses there is a danger of escaping hydraulic medium under
pressure, or of the hoses whipping around.
»» The hoses should be subjected to a visual inspection (leak-
tightness, surface damage such as kinks) after every use and at least once per year
Structure and function | 21
»» Every three years, or in the event of doubts about the safety or reliability, carry out an additional functional and load test (as per DGUV Grundsatz 305-002 or specific national directive).
»» Replace hoses every 10 years! The date (code letters or quarter/year) is specified on the hose bonding.
»» Ensure that the hoses are not exposed to tension or torsion (turning).
»» Do not kink the hoses or draw them over edges (smallest bend radius 40 mm).
»» Do not subject the hoses to high temperatures.
»» Protect hoses from contact with materials that can cause damage to the outer covering e.g. acids, alkalis, or solvents.
Hydraulic oil
All spreaders are designed and tested for WEBER hydraulic oil Part no. 804932. This oil
possesses a particularly high purity level and also works flawlessly at temperatures
below zero, down to -20° C.
With limitations in the low temperature range (low output), however, a standard oil (mineral
based) of viscosity class HLP 10 or HVLP 10 can be used in keeping with DIN 51502.
We recommend the following hydraulic oils for trouble-free operation
of WEBER rescue devices:
AERO Fluid 41 (Shell)
Univis HVI-13 (Esso)
Aero-hydraulic 520 (Total)
Hydraulik DB (Castrol)
Renolin/MR310 (Fuchs)
HVI Extra 380 (Maier & Korduletsch)

When using the SINGLE coupling, pressure relief connectors are no
longer required.
Structure and function | 23
Plug-in coupling (SKS)
Remove the protective cap from the coupling male. Take hold of the coupling female by
the knurled sleeve cover and pull out the protective plug. With one hand take hold of sleeve
cover of the coupling female, with the other grasp the coupling male (black) by the hex nut,
and press the sleeve cover slightly against the coupling male until the ball bearings engage.
Twisting the male coupling slightly when pressing togehter eases the coupling process.
Grasp the coupling male (black) by the hex nut with one hand and with the other take
hold of the sleeve cover and draw it back. The disconnecting will cause a few drops of hydraulic
oil to escape. Plug in the protective caps immediately.
When coupling SKS connections the power unit operating lever must be in
the „0“ position.
A pressure relief connector is fitted to the hydraulic power units and
the hand pump, with which a few drops of oil can be discharged from
the hoses. This permits re-coupling following pressure increases in decoupled equipment.
In this case simply insert the pressure relief connector into the
coupling sleeve and turn the knurled screw to the right until oil leaks
24 | Structure and function
The following section only pertains to the SINGLE coupling. When
connecting SKS couplings first ensure that the control lever is in the „0“
Use of the control handle
The spreader can be operated by the pushbutton on the control handle. The speed of
movement of the spreading arms is controlled precisely by the greater or lesser degree of
force applied to the pushbutton.
The maximum spreading force is only applied when the pushbutton is fully depressed.
Opening the spreader
The primary motion direction of the device (opening) is triggered by pressing the lower tapered
(convex) end of the button.
The direction of movement is marked on the equipment with the symbol:
Closing the spreader
The spreader is closed with the upper curved (concave) end of the button, which is marked with
the following symbol:
Dead-man‘s switching
If the pushbutton is released then it returns to the neutral position automatically. With this, the
device stops still in any position (including under load).
Structure and function | 25
Changing the spreader tips
The spreader tips are secured in the spreader arms with removable collar studs (with the
exception of the SP 35 AS and the SP 53 BS). In order to change, press out the studs secured
by a spring-loaded ball. After changing the tips, push the collar studs back in again. When
doing this ensure that the studs are correctly fitted (completely pressed in).
Fitting the bracket for the chain set is identical. The chain lock must be fitted with the lock
facing upwards.
The collar studs on the SP 53 spreader tips can be pressed out of the spreader arms but have a
safety system to prevent them being lost and so they cannot be separated from the tips.
The SP 35 AS spreader tips are not secured with removable collar studs but rather with a
tensioning pin that must be knocked out when the tips are being changed. The chain set can be
fastened in a separate hole without having to remove the tips beforehand.
26 | Possible applications
5 Possible applications
Safety information
Never reach between the spreader arms!
During all work with the spreaders, parts which are tensioned can break off
or be blown off and thus endanger personnel.
Therefore, personnel who are not directly involved must maintain a
safe distance or only stay in the hazardous area as long as is strictly
With the help of the spreader function, it is possible to open doors, lift vehicles and
other moveable loads, push away vehicle parts and crush tubes and pillars, amongst other
things. A stable positioning and support of the vehicle is essential with this.
In order to avoid slipping off when spreading, the arms and tips are serrated on the inner and
outer sides.
It is best to spread using this area because the spreading force is highest here. In
addition, slipping of can be avoided by readjusting the spreaders. If possible the tips should
only be used to enlarge a gap.
Possible applications | 27
After the chain set (as explained in chapter 4.6) has been mounted on the spreader tips, the
spreader device can be used for pulling.
For this, the chains must be tightly tensioned and must be tensed only in the pulling direction.
To tension the chain, only one lock can be pressed in, so that the chain can be pulled through
the holder.
If the range of movement is not sufficient, tension chains or other means must be used so that
the spreader can be reopened and the chain retensioned.
Store the pulling chains with locks mounted about 10–20 cm from the end.
Check the chains prior to every use. Check that the weight does not stress
the tip of the hook, but lies in the middle of the hook instead.
»» Do not make any repairs on your own.
»» Do not stress the chains beyond the permitted load carrying capacity.
»» Do not load with a jerking movement.
»» Do not galvanize or paint the chains.
»» Do not shorten the chain by knotting it.
»» Do not subject the chains to heat stress.
»» Use the chains and accessories only between –40°C and +200°C.
»» During all maintenance work, observe the applicable German accident prevention regulations (UVV) as well as the specifications of DIN EN 818-7 and DIN 685-5.
»» Chains must only be used for lashing. Lifting loads is not permitted.
28 | Possible applications
Chains must not be used if:
»» Deformations, cracks, signs of corrosion are present.
»» The wire diameter of the chain link has decreased by 10% of the nominal thickness.
»» An individual chain link has been permanently stretched.
»» An individual link has been enlarged by more than 2%.
»» The internal chain pitch over a measuring distance of 11 chain links has increased by more than 2%.
Pipes and other hollow profiles are crushed by closing the spreader arms.
If possible obly use the tips to crush material. With the old SP 35 with steel arms it‘s
also possible to use the fluted area of the arms.
Material to be crushed can suddenly jump away.
Do not remain in the work area of the spreading devices!
Possible applications | 29
The spreaer can also be used for lifting vehicles or other movable loads.
Care must be taken to secure the load against slipping away and to position the spreader tips
far enough apart under the load to prevent slipping.
The load being lifted must be constantly monitored (tipping, rolling away or changing position).
Also, the lifted load must immediately be propped up and supported in a suitable way.
In order to create entry points in bus accidents, train accidents, silos etc. it is possible to
use the spreader tips as a peeling tool.
