2. 100 YRM 582 Description
General
This section has a description and the service procedures for the parts of the frame. These parts include the frame,
counterweight assembly, overhead guard, hood and seat assembly, access panels, and label positions. The proce-
dure for removing the traction motor is also described in this section.
Description
MAIN FRAME
The main frame is a single weldment. See Figure 1.
The main frame has mounts for the following:
• Counterweight
• Overhead guard,
• Battery restraint and hood
• Tilt cylinders
• Steering axle
• Drive axle assembly
• Cowl assembly
• Floor pedals and floor plates
• Side step and fender weldments
• Hydraulic tank
• Pump and motor assemblies (steer, lift, and traction
motors)
• Control valves, and the levers
The hood is part of the operator and battery restraint
system. The seat is part of the operator restraint sys-
tem. The floor plates can be removed for access to
the traction motor. The panels on the sides of the bat-
tery compartment can also be easily removed. The hy-
draulic tank, lift pump motor assembly, and the steer-
ing pump motor assembly are in a compartment be-
tween the battery and the counterweight. The SCR
(silicon controlled rectifier) or transistor electronic con-
trollers and contactors are in the top of the counter-
weight. The top cover of the counterweight can be re-
moved for access to the controllers and contactors for
early model ERP20-30ALF (B216) lift trucks. See Fig-
ure 2. The rear cover of the counterweight can be re-
moved for access to the controllers and contactors for
later model ERP20-30ALF (B216) trucks and ERP20-
30ALF (ERP040-060DH) (D216) trucks. See Figure 3.
There are two main frames for lift trucks made for use in
North America and two main frames for lift trucks made
for use in Europe. The frames are different because
of the different battery compartment sizes. There are
two battery compartment lengths. The battery com-
partment widths are also different for Europe and North
America. See Battery Specifications, at the back of this
manual.
WARNING
The battery must fit the battery compartment so
that the battery restraint will operate correctly. A
loose battery can cause serious injury and property
damage if the lift truck overturns. Adjust the spacer
plate to prevent the battery from moving more than
13 mm (0.5 in.) forward or backward.
WARNING
Maximum clearance between the battery and bat-
tery compartment width is 13 mm (0.5 in.). Maxi-
mum clearance between the battery and the spacer
plate is also 13 mm (0.5 in.). The Battery Specifica-
tions chart shows the minimum size compartment
allowed.
The weight of the battery is a large part of the coun-
terweight system on an electric lift truck. Make sure
that the battery is within the weight limits indicated on
the nameplate. Each model of lift truck has a cast-iron
counterweight that provides the additional weight nec-
essary for the indicated capacity.
OTHER FRAME WELDMENTS
These frame parts are the right-hand and left-hand side
step and fender weldments, and the cowl weldment.
See Figure 1. Each part is a weldment fastened to
the main frame to make the frame assembly. The cowl
weldment is a mount for the front of the overhead guard
(see Figure 2 and Figure 3), the steering column as-
sembly (see Figure 4, Figure 5, and Figure 6), the re-
lease linkage of the parking brake, and the instrument
panel with light switches. The display panels for these
models of lift trucks are mounted into the instrument
panel. See Figure 4, Figure 5, and Figure 6.

OVERHEAD GUARD
WARNING
Do not operate the lift truck without the overhead
guard and cowl correctly fastened to the lift truck.
The overhead guard is a weldment that fastens to the
main frame and cowl to help protect the operator from
falling objects. For early model ERP20-30ALF (B216),
see Figure 2. For later model ERP20-30ALF (B216)
and ERP20-30ALF (ERP040-060DH) (D216) trucks,
see Figure 3. A slot in the overhead guard permits
removal of the battery without removing the overhead
guard.

BATTERY AND OPERATOR RESTRAINT,
HOOD, AND SEAT ASSEMBLY
Battery Restraint
WARNING
The hood and battery restraint, as well as the latch
for the hand lever assembly, must operate correctly
before a lift truck is operated. These parts are part
of the battery restraint system. The battery restraint
system must operate correctly to help provide rea-
sonable protection to the operator if the lift truck
tips over.
A battery restraint system is installed as a safety device.
See Figure 7. The function on the battery restraint sys-
tem is to hold the battery in the battery compartment in
case of a tip over. Part of the battery restraint system
is a battery restraint rod at the rear of the battery com-
partment. See Figure 7. This restraint rod extends over
the rear edge of the battery case to help hold the bat-
tery within the battery compartment during a tip over. A
handle is used to move the restraint rod. The handle
of the battery restraint must be in the DOWN position to
close the hood. The handle can be moved to the DOWN
position only after the restraint rod is extended over the
battery. The restraint rod can only be retracted when
the hood is in the UP position.
WARNING
The battery must fit the battery compartment so
that the battery restraint will operate correctly. A
loose battery can cause serious injury and property
damage if the lift truck overturns. The battery must
not be able to move more than 13 mm (0.5 in.) for-
ward, backward, or side to side.
An adjustable spacer plate is used at the front of the
battery compartment to prevent forward and backward
movement of the battery. See Figure 8. The adjustable
spacer plate is used inside the battery compartment.
See Figure 8. The spacer plate must be adjusted for
a maximum clearance of 13 mm (0.5 in.) with the bat-
tery against the rear bulkhead. There must be some
clearance to allow battery removal. See the section
Periodic Maintenance 8000 YRM 552 for both early
and later model ERP20-30ALF (B216) trucks and Peri-
odic Maintenance 8000 YRM 1060, for ERP20-30ALF
(ERP040-060DH) (D216) models, to remove the battery
and adjust the spacer plate.

WARNING
The gas springs for the hood can raise the hood at
a rapid rate and cause an injury. DO NOT get over
hood when raising hood.
WARNING
The batteries for these lift trucks must fit the bat-
tery compartment width with a maximum of 13 mm
(0.5 in.) clearance. The Battery Specifications at
the back of this manual, shows the minimum sizes
of the battery compartments.
Another important part of the battery restraint system
is the steel weldment that is also the hood frame. See
Figure 7. This hood frame is connected to the lift truck
frame with hinges at the rear of the hood (see Fig-
ure 13). The front of the hood and frame is locked in the
closed position by the assembly for the hydraulic hand
levers. A latch releases the assembly to tilt forward and
allow the hood to raise. See Figure 9. Gas springs help
lift the hood assembly. The seat and other parts of the
operator restraint system fasten to the hood assembly.

Operator Restraint System and Seat
Assembly
The operator restraint system has the seat, hip re-
straints, and the seat belt. The system helps the
operator stay within the lift truck in case of a tip over.
See Figure 10.
Make sure that the seat is not loose on the rails. Make
sure the seat rails are not loose. The seat rails must lock
securely in position, but move freely when unlocked.
The seat rails must be securely attached to the mount-
ing surface.
