SERIES USA ARMY TYPE TROLLEY HOISTS

Spark and Corrosion Resistant Models

DESIGN FEATURES:
Trolley Hoists
USA Army Type Trolley Hoist has the advantage of decreasing the headroom
with close coupled trolley connection. The trolley hoist delivers tighter headroom
where just a couple of inches greater lift is of utmost importance. USA Army
Type Trolley Hoist is a variation of the hook suspended hand chain hoist. Rather
than the standard hook suspension, trolley hoists have a lug suspension to permit
a rigid mount trolley to be attached to the hoist…making up the trolley hoist unit.
Trolley can be either a push or hand geared model. The 1-ton model, because
of its compactness, requires a special hand chain wheel extension for the chain
wheel to clear a monorail beam. Subsequently, the trolley for the 1-ton unit
includes anti-tip guide rollers to prevent trolley tipping when the hand chain is
pulled to raise or lower loads.
Construction Features
Frame: The frame of the USA Series Hoist is a tough, impact resistant,
lightweight, heat treated, permanent mold cast aluminum alloy. The frame is
heavily proportioned, designed primarily for rigidity to hold the gears and
bearings in close alignment. The frame with the covers encloses all operating
parts protecting them from dirt and the weather.
Overload Device: The chain wheel, in addition to having pockets accurately
formed to receive the links of the hand chain, also forms a part of a unique patent
pending overload device as a standard feature. The overload device is calibrated
for the capacity of the hoist and factory installed as an added measure of
protection for the load, hoist, and operator.
Gearing: The gearing is straight spur for good efficiency. The gears and pinions
are generously proportioned and precision cut from alloy steel and heat treated
for max- imum strength and durability. All gears are grease packed in a grease
tight gearcase.
Load Brake: The automatic, screw actuated, Weston-type load brake holds
the load under all conditions and permits fine smooth control in lowering. The
brake is self-adjusting with the friction washers long wearing, requiring low
maintenance.
Load Sprocket: The load sprocket and sprocket gear are machined from
one-piece steel forging. The chain guide is a heat-treated, spring steel, flexible
guide which provides heat-treated smooth surfaces that flex in the frame,
controlling the load without binding.
USA Army Type Trolley Hoists
Load Chain: Closely calibrated chain links of special analysis alloy steel formed
and heat-treated for unusual strength, carbonized for long wear and usage. The
links are accurately formed to fit the pockets of the load sprocket.
Hand Chain: The hand chain is welded steel and zinc plated for corrosion
resistance and “clean hands” operation. The chain links are accurately formed
to fit the pockets of the chain wheel, for gag-resistant operation in the chain
wheel and guide arrangement.
Hooks: The hooks are drop forged steel and are tough and ductile so that they
will open noticeably when subjected to excessive overload. They are full
swiveling, and each is equipped with a spring type hook latch.
Spark and Corrosion Resistant Models: Spark and corrosion
resistant models are designed for service in certain hazardous
atmospheres and areas where resistance to friction sparks is vitally
important. These models have: bronze alloy hooks; bronze block
sleeve or aluminum lower block; special chrome nickel stainless
steel alloy load chains; and aluminum or bronze hand chain.

Series USA Army Type Trolley Hoists - Spark & Corrosion Resistant
Push and Hand Geared Type
Capacities: 1/4 to 6 ton
The USA Army Type Trolley Hoist is offered for those applications where a
closer headroom is required. It consists of a lug suspended model USA Hand
Chain Hoist with a Rigid Mount Trolley. The lug hoist contains all the fine features
of the USA Chain Hoist with the exception of substituting a lug suspension for the
normal hook suspension.
