CRANE INSTALLATION
HT40KX, HT50KX
BODY REINFORCEMENT
The truck body must be reinforced and outriggers provided to withstand the combined loads
resulting from lifting and the weight of the crane and boom.
The maximum combined overturning moment for the HT40KX is 45,000 ft. lbs. and for the
HT50KX is 55,000 ft. lbs.
The maximum vertical load for the HT40KX is 7900 lbs. and for the HT50KX is 9900 lbs.
CRANE MOUNTING
The crane base plate or mounting pedestal must be bolted to the body reinforcing plate with
eight (8) grade five (5) bolts of 1" dia. with either coarse or fine threads. A 7" dia. hose clear-
ance hole must be cut in this plate to allow the hoses to swing and coil freely.
ROTATION POSITIONING
The HT cranes are shipped with the boom rotated to the middle of the 400 degree rotation
travel limit. The location of this middle position relative to the center line of the truck must be
decided prior to mounting. It can be in any position that pleases the user since the boom can
always reach the storage and travel position by rotating one way or the other.
HYDRAULIC CONNECTIONS
The crane is furnished with a pressure and a return hose that come down through the center of
the quill. Included in the installationkit are two hydraulic swivels and two more hoses. These
hoses and swivels are to be arranged in the compartment or pedestal below the crane as
shown on drawing 20698 using the angle bulhead fittings also furnished in the installation kit.
These hoses are to be connected in a relaxed position as shown on 20698, while the crane is
at the midpoint of the 400 degree rotation range as received -- regardless of the final position
of the boom during storage/travel.
The bulkhead fittings may be located on any side of the compartment relative to the middle of
rotation position.
The crane pressure and return hoses have different sizes of SAE 37 degree flare swivel
fittings. The smaller swivel is on the pressure hose which has a 3/8" flare (#6 JIC). The larger
swivel is on the return hose which has a 1/2" flare (#8 JIC).
