Available Hydra-Handler Options
Centurion: Lift, Travel, Proportional Control
PLC controlled hydraulic valves which allow for faster lift, smoother start and stop, easier feathering
of the controls, and adjustability of the lift and travel functions. The PLC controlled hydraulics allow
for much smoother operation of the HHA shortening the training cycle of operators and extending
the life of hydraulic components. Centurion can be set at slower speeds during initial startup and
faster speeds after operators become more comfortable with the equipment.
Heavy Duty Unit with 5” Uprights:
Heavy Duty Unit with 5” uprights. This is for customers with the most difficult applications i.e.:
heaviest use (>200 batteries), heaviest batteries, (sit-down batteries vs. pallet jacks), 3 shift
operations with many employees using the equipment. The Heavy duty advantage is durability and
product life.

Maintenance Sensor Package
The Maintenance Sensor Package helps ensure that downtime for the Hydra Handler is scheduled
rather than emergency. With sensors monitoring key operational characteristics unscheduled
downtime is avoided since early warning is given when an out of tolerance situation occurs. Service
can then be planned for when requirements for changing batteries are minimal or non-existent.
Hydraulic pressure and temperature, drive chain tension, vacuum pressure, and lift bed level are
continuously monitored to against prescribed tolerances. When an out of tolerance alarm is active
the touch screen monitor utilizes embedded photos and text to describe the failure mode and the
method for adjusting the machine to within specification.
This option also includes an on-screen preventative maintenance schedule detailing prescribed
tasks for the Hydra Handler and a checklist for daily safety inspections. Having this information onboard makes it easier for service personnel to properly maintain the Hydra Handler to factory
A component identification module is also accessible from the touch screen monitor. Photos
identifying various Hydra Handler components and their part numbers simplify the process of
replacement ordering of parts. This is a speedy alternative to the hard copy manual also supplied
with the Hydra Handler.
Semi Automated Battery Extraction and First in First Out battery utility
Benefits of this option include:
• Elimination of dedicated battery change operators
• Reduced time for each battery change
• Reduced wear and tear on forklifts, Hydra Handler and charging stands through automatic
• Increased safety to personnel during the change-out process
• Proper rotation of all batteries in the system through use of the First In, First Out utility
This option takes operator skill out of the process by automatically positioning the Hydra Handler at
every step of the battery change-out process. Skill levels of forklift drivers tasked to change their
own batteries vary greatly. As such, wear and tear on a key piece of equipment can be high. This
option allows for safe, efficient, and timely transfer of batteries without extensive training or skill
The integrated touch screen monitor leads the operator through each step ofthe battery change-out
process. Dead-man switches on the machine ensure that the operator is safe throughout the
process. SICK laser personnel sensors also protect against the machine contacting personnel or
equipment that inadvertently move into the travel area of the Hydra Handler.
When the forklift operator arrives to change a battery he positions his truck to a predetermined
location, unplugs the battery, and lifts the battery stop in preparation for the change-out. He then
boards the Hydra Handler engaging the man–aboard switch on the platform and closes the gate to
the operator compartment. When both of these safety interlocks are engaged the touch screen
monitor prompts the operator to choose the truck type he requires a battery for.
The First In, First Out utility recognizes which battery is required and with the operator safely
holding both pistol grip dead-man switches the machine positions itself to extract the dead battery
from the truck. After doing so the Hydra Handler positions itself so the operator can disconnect the
new battery from its charger. Next the machine extracts the new battery from the rack, repositions
itself to move the dead battery into the now open charging slot, move the battery into the slot and
reposition itself for the operator to connect the dead battery to the charger. It then puts the new
battery in the truck and moves itself into a resting position so the operator can de-board, connect
the new battery to the truck, install the battery stop and return to work.
At every step of the process the operator is prompted to perform tasks such as connect or
disconnect the battery. Dead man switch controls ensure operator safety during the change-out
process by not allowing operation of the Hydra Handler unless properly activated.
6-Powered Rollers
This option increases the efficiency of the change-out process because the operator can move the
extractor arm out of the way earlier. Powered Rollers are used to move batteries on and off the
battery changer when the extractor arm can no longer be used. This option increases the number
of powered rollers in each battery compartment of the Hydra Handler increases from four to six. The
additional powered rollers being outer most of the battery compartment allow the extractor arm to
be moved out of the way earlier.
On-Board Watering System
On board tank, pump and filler gun allow for watering batteries in the charging stands. This option
is used in conjunction with single point watering systems. This Hydra-Handler mounted system
makes the labor intensive battery watering process much more efficient by allowing the batteries to
remain in the charging stands during watering vs. the standard practice of removing, watering, and
Laser Pointer Guidance
Centered, under-compartment lasers allow Hydra-Handler operators to speed up battery changes
by pointing to the proper height on charging stands and lift truck battery compartments.
Limit Switch
The height Limit Switch option will stop the Hydra Handler from lifting higher than a preset
dimension. This option allows for a Hydra Handler to reach the upper most level of battery storage
but stops it before going higher. This option would be appropriate for applications where overhead
obstructions could be a problem. It has the potential to allow another level of battery charging
compared to a unit without this option. An appropriate application would be a room with low ceilings
but room to stack chargers behind the racks rather than on a catwalk.
7” Operator Step
This lowers the step to the operator’s compartment from 12” to 7” making it easier for operators to
step onto the machine for changing batteries
Key Switch/Operator Lockout:
Standard mechanical key switch added to Hydra-Handler to prevent unauthorized personnel from
operating the HHA
Mechanical Battery Stop:
This option is a must for single sided systems to protect against accidental discharge of a battery
on the open side above a preset dimension. The preset dimension is set an inch or two above the
highest “R” dimension of the trucks being used in the battery charging system. Utilizing a cam and
follower system the flip ups engage as the Hydra Handler is lifted above the preset height. With the
flip ups engaged a battery will be stopped if the roller deck is used to move it towards the open side
of the rack system. For 2 sided systems with unequal rack coverage a flip up system can be
engineered specific to the customers needs at a higher cost for the customization.
Roller Deck Lock
The roller deck lock utilizes the sensors in each battery compartment (2 on each side of the HHA) to
stop the roller deck in order to protect against accidental discharge of a battery. When the roller
deck moves a battery into the plane of the compartment sensors the roller deck is “locked” until the
operator activates the override button and roller deck control at the same time. Therefore the
operator must consciously decide he wants to continue moving the battery in the direction it was
going prior to the roller deck locking by pressing the override button. This is a safety option that will
reduce but not eliminate the possibility of accidentally discharging a battery on the wrong side of a
Strobe Light with Motion Alarm on HHA:
Flashing, rotating amber strobe light added to either front or rear of HHA that provides visual
indication of HHA operation. This option is available with or without an audible alarm.
SICK Laser Personnel Detection
These safety detection systems will sound an alarm and/of shut power off to the Hydra Handler if
personnel or equipment inadvertently enter the travel area when Hydra Handler is powered. One
can be positioned at each end of the Hydra Handler. These are already incorporated in the SemiAutomated Positioning option.
Remote Lowering in Operator Compartment:
Provides a method for the operator is lower the HHA in case of power outage when unit is raised.
12” Hydraulic Extension Cylinder
This option would only be required if trucks with outriggers are utilized. Extraction reach with the
Hydraulic Extension Cylinder is 18 ½”
Low Arm Requirement (Short Batteries)
This option allows vacuum cup of extractor arm to attach to batteries shorter than 11” high. This
option is typically required when access to AGV batteries is required.
Single Compartment HHA:
This option reduces the overall length of the Hydra-Handler and is typically used when available
system length is at a premium. While reducing the length, the single compartment Hydra-Handler
requires an empty charging stand accept spent battery before charged battery can be loaded that
increases battery change out times.
