- Minimum of 18,000 pounds lifting and dumping capacity.
- The hooklift shall have a minimum of 57 degree dump angle,
on a 40" truck frame height chassis.
- hooklift not to exceed 3,000 lb. in shipping weight.
- hooklift must be able to handle skid-mounted containers/bodies
with sub frame lengths of 14 through 18 feet.
- The skid-mounted containers/bodies must be supported by flanged rollers at the rear of the hoist. The rear-flanged rollers must have a minimum diameter of 6 ¼”.
- The flanged rollers at the rear of the hoist must be adjustable to accommodate bodies/containers with outside sub frame rail widths of 41 5/8” to 40 ½”.
- The hook to rear roller dimension to be 153.88”in
length.
- Dump/load cylinders are double acting, twin cylinders,
sized for unit capacity with double integral counterbalance
valves. Dump/load cylinders to be a minimum 5.25” bore by
54” stroke and manufactured in the USA.
- Telescoping jib section shall be double acting, single
cylinder sized to unit capacity with a single counterbalance
valve. Jib cylinder to be a minimum 3" bore by 36" stroke
and manufactured in the USA.
- The hooklift jib must be capable of hydraulically sliding the body/container horizontally on the chassis, without lifting off the hoist frame rails, to adjust weight distribution while remaining in the body locks.
- Must have a jib lock out valve to prevent jib operation while in the dump mode.
- Jib hook to be capable of reaching rearward to A-frame lifting bar by double articulating hinge points in the hoist mechanism.
- All lift sections must lock into a common rigid full-length frame to support the body/container when dumping. This must be accomplished by mechanical operated latches, which lock the mast without relying on gravity, or hydraulic locks.

- The mainframe of the hoist is to be constructed of a “Z” rail
configuration. The “Z” rail mainframe is to
be a maximum of 7.5” in height and constructed of
1/4” grade 50 steel.
- Hoist “Z” frame rails to include a minimum of 6 ( 3 per side), 11 ¾” X 2 ¾” X ½” nylatron wear pads at the front of the “Z” for front body/container support. This nylatron pad will allow the containers/bodies to slide back and forth on the rail of the hoist with ease. Metal to metal contact (the metal sub frame of the container/body ride on the sub frame of the hoist) will not be allowed.

- Direct mount gear type pump, 11.4 gpm at 1000 rpm, 3,250 psi maximum system operating pressure.
- 15-gallon oil reservoir tank (minimum) is to have a sight glass to indicate fluid level with integral thermometer. Must contain a 200 mesh, 74 micron screen strainer.
- Must contain a return filter assembly with replaceable 10-Micron filter cartridge.
- Control valves to be stackable type with J.I.C. 37-degree fittings.
- High-pressure hoses to be SAE 100R2 type AT or equivalent, rated for 3,250 PSI (maximum) working pressure.
- System must contain an integral 3,250-psi relief valve.
- Dual control levers cable operated mounted in truck cab. Controls are to be spring centering type for safe operation.

- The complete mechanism, including hydraulics, to be made in the U.S.A. with service and parts readily available.
|
|
- Must have integral slide through lock down plates to secure body to hooklift in dump and transport positions, to accommodate different length bodies and to allow for weight distribution changes while remaining in the body locks when in the transport or in dump cycle.
|
|
- Jib Hook to accommodate both 35.63" and 54" heights
when measured from bottom of the long sills to the
bottom of the hook by utilizing a dual height rotating
jib hook.
- Dual Height Rotating Jib to exchange between hook heights
by gravity alone through the operation of the Hook-lift
hoist, and without the need for powered or manual adjustment.
- Hook-lift must be able to pick up body or container resting
on a grade 4.5" below the grade the truck is on (assumes
40" truck frame height).
- Jib hook to be so designed to secure body to hoist without
the need of a security safety latch.
|
|
- The “A” frame of the container/body shall be constructed to allow the hooklift operator to approach and load the container/body on the truck chassis from an angle.
- The skid-mounted container/body must have integral slide through lock down plates to secure body to hooklift in dump and transport positions, and to accommodate different length bodies or weight distribution changes while remaining in the body locks.
|
|
- The complete mechanism, including hydraulics, will be factory warranted free of defects in material and workmanship for a period of thirty-six (36) months on parts, 90 days on labor from the date of installation.
|
|
- Hoist must be capable of being mounted to a truck chassis
of 120" to 138" cab-to-trunion dimension.
- Truck frame to have RBM of 600,000 in.-lbs. per frame
rail (1,200,000 in.-lbs. total).
