LOAD HANDLING SYSTEM (LHS) - Continued
Loading/unloading to/from trailers or ramps in which the height is equal to or less than the
height from the ground to the bottom of the FR (while on the vehicle).
LHS (1) with CHU kit is capable of the following with a flatrack (FR) or container totaling
24,000 lbs (10 896 kg):
Loading/unloading the FR from the vehicle to 12 in. (30 cm) below ground level and any
intermediate level.
Loading/unloading from uneven ground slopes of 5 degrees from the vehicles lateral and
horizontal axis.
LHS (1) is capable of the following, with a forward repair system (FRS):
Loading/unloading the FRS from the vehicle to 1 ft. (30 cm) below ground level and any
intermediate level.
Loading/unloading from uneven ground slopes of 5 degrees from the vehicle's lateral and
horizontal axis.
Flatrack Locking.
LHS (1) is designed with automatic locking features that secure the FR
for all modes of transportation. LHS (1) can automatically guide, center, and secure a FR
to the vehicle so that even during rough trail operations, the FR remain safely secured.
LHS Overload.
LHS (1) will not function when the payload exceeds 11 tons (9 988 kg)
maximum. A warning indicator (4), located in the cab in plain view of the driver, activates
when a FR with a payload of 11 tons (9 988 kg) is being loaded by the LHS while under the
worst conditions.
Hydraulic System.
Hydraulic filters are located to provide direct access and to allow
removal without damage to the vehicle. Bypasses are furnished where necessary to protect
filters during cold temperature operation. All cylinder rods exposed during operation have
a hard chromium plating.
Slave Hydraulics.
Self-sealing, quick disconnect hydraulic couplings and a hose with
appropriate connectors are provided so that one M1120 LHS vehicle can readily
hydraulically power the LHS (1) of another M1120 LHS vehicle.
CONTAINER HANDLING UNIT (CHU)
The CHU utilizes the LHS (1) to load/unload ISO containers and shelters onto the vehicle.
