Work-rated@ Hoists
Capacities-l to 25 fons*
These hoists are engineered to meet your
particular material handling needs. Severe,
heavy and normal duly Work-Rafed models
are offered in each capacity. You buy exactly
the hoist you need, no more, no less.
The basic conf iguration of the one ton hoist
is the same as the twenty-five ton capacity
unit, providing a unif ied design approach
that makes Ihe Work-Rated line the most
complete family of hoists available. This
design unity also simplifies maintenance.

PARALLEL MOUNTED HOISTS
When lateral hook travel, headroom and
end approach are not concerns, a parallel
mounted Work-Rated hoist provides a good
hoist value. The hoist travels in a
lengthwise position to the beam or track
and requires no counter balancing. Single
reeving is the most economic choice, but
when lateral hook travel presents a problem,
double reeving, with true vertical lift,
is also available on oarallel mounted
hoists.
CROSS MOUNTED HOISTS
For situations where headroom and end aoproach
dimensions are critical, cross
mounted Work-Bated hoists, that travel
perpendicular to the track or beam, offer
the closest minimum operating profile of
underhung hoists.

TWIN HOOK HOISTS
Work-Rated twin hook hoists are designed
for lifting long or bulky loads. The twin
hooks provide support at two
points...minimizing load sway, tipping or
rotation. The compact close headroom profile
is ideally suited for severe duty applications
in patented track, bridge cranes and
lifting sections. The strong steel frame,
when attached to either a plain, geared or
motorized trolley, makes lifting and
transporting bulky loads easy. The balanced
hoist design centers the load hook
directly under the track and elim inates tippino
as the load varies.
ELECTRIC WINCHES
Work-Rated winches meet specif ic lifting or
pulling needs where conventional hoist
reeving is not required. Base or wall
mounted models are available with single
and double line reeving and have the same
proven Wright constructron features as
Work-Rated hoists, except for the gravity
limit switch and the Wright overload cutoff.

DECK/BASE MOUNTED HOISTS
Deck or base mounted hoists are designed
for lifting applications where hoist movement
is not required, or where the crane
builder will fabricate his own trollev.
TOP RUNNING TROLLEY HOISTS
Our largest capacity Work-Rated hoist that
are designed to run on top of the double
girder crane bridge. A Work-Rated hoist is
mounted on a frame of welded ductile
structural shapes for maximum strength
and wheel/bearing alignment, with an independent
trolley drive motor that drives
the trolley through the wheel axles.

Wright-Wayt Hoists
Capacities-l14 to 2 Tons
Wright-Way hoists are built with many of
the same construction features as the
Work-Rated and Wright American hoists;
construction fealures unioue to hoists of
their size and orice.
The exclusive patented Wright overload
cutoff is standard equipment on all Wright-
Way hoists. The device protects the
operator, the load and the hoist by sensing
an excessive overload and interrupting the
lifting circuit, preventing lifting but allowing
the overload to be safely lowered and
removed. The device then automatically
resets and the hoist is ready for the next lift.
Othet Wright-Way lealures include; dual
braking using an electric motor brake and a
12
mechanical load brake, automatic reset
thermostats in the motor windings, a combination
of helical and spur gearing encased
in an oil-tight aluminum housing, easily
accessible controls in a tough NEMA 3R
enclosure, ductile iron lifting frame and
preformed aircraft grade steel wire rope on
a steel drum with machined grooves and
large f langes.
Wright-Way hoists are available in lug,
plain, geared and motorized trolley suspensions.
In addition to operating on structural
beams, standard Wright-Way trolleys can
operate on 3.25 and 3.33 inch patented
track.

GEAR TRAIN
Quiet, compact helical gearing and external spur drum gear are
enclosed in the same oil-tight housing. All gearing is machine cut,
heat-treated alloy steel with shock-resistant ductile cores. Gearing is
designed to AGMA standards for maximum life, and operates in an oil
bath. Rugged aluminum alloy housing provides rapid heat dissipation.
EEARINGS
Precision heavy-duty ball bearings support allshatts. All bearings are
either solash lubricated. or lifetime Dre-lubricated and sealed.
HOOK
Drop forged heat-treated steel hook swivels 3600 on a shielded roller
thrust bearing. Spring latch is standard.
WIRE ROPE
Either improved plow steel (lPS), or extra improved plow steel (XPS) is
supplied on Work-Rated and W ght American hoists. Prelormed aircratt
quality steel wire rope is supplied on Wflghl-Way hoists.
CONTROLS
Choose lrom single., 2.speed or s.step variable speed on wo*-Rated
hoisls. On Wright Ametican and Wright-way hoists single and two
speed motors are available. Controls are magnetic reversing type,
mechanically and eleclrically interlocked with 115.V control circuit.

MOTOR ERAKE
Wright rcclilied D-C magnet-actuated disc brake has been proven in
millions ot hours of in-service operation. lt delivers rapid stops with
minimum to zero hook dritt. The motor brake assembly is seperated
from the gear housing for rapid cooling. This multiple coil brake is
rated a minimum ot 150% ot lull load motor torque.
Exclusive brake-sensing microswitch, standard on Work-Rated and
Wtight Ametican hoists, prevents molor from operating against the
engaged brake. lt also prevents the motor from operating when brake
requires adjustment.
OVERLOAD CUTOFF
Exclusive palented Wright unit is standard on all Work-Rated and
Wtight-Way hoists except single line models. Protects load, hoist and
operator by interrupting raising circuit when hoist is overloaded. The
electro-mechanical device is designed to interrupt the hoist lifting cir
cuit if the load it senses exceeds the preset capacity of the cutoff
device. When the lifting circuit is interrupted, the lowering circuit remains
intact to allow the load to be lowered and removed. When the
overload is removed, the lifting circuit is automatically restored.
MECHANICAL LOAD BRAKE
Automatic Weston-type multiple disc brake can hold a tull capacity
load independent of motor brake. This brake assures that load does
not accelerate while being lowered. No wear compensation adjustment
is reouired.
MOTOR
Standard NEMA flange, Class F Insulation, 3o-minute duty motor is
provided for standard commercial power supplies. The motor has a
standard NElt A shaft extension.
DRUM
The large diameter steel drum has deep machined grooves and large
flanges. At least two full turns of rope remain on the drum at the
lowest hook position of rated lift.
TROLLEY WHEELS
On the Wotk-Rated and Wright American hoists trolley wheels are
forged steel with machined and hardened treads. On lhe Wright-Way
hoists wheels are cast iron with hardened treads. They come complete
with pre-lubricated, sealed, heavy duty ball bearings.

(a)4 PD Reeving shown does
nol apply to lhe WRIGHT
AMERICAN hoist.
Common Applications ol HOIST Reevings
Reeving refers to the configuration of the wire rope, blocks
and drum of the hoist. Beeving elfects headroom, lifting
speed and capacity by increasing the hoist's mechanical
advantage. Reeving also determines if the hoist has lateral
hook movement or true vertical lift.
The three terms used in reeving ate; single, double and
part. Single or double refers to the number of ropes coming
from the drum. Part deals with the mechanical advantaoe
gained by multiple reeving. For example. with two ptrt
single reeving (2PS) the load is distributed over the two
parts, and the mechanical advantage doubles the capacity
of one part reeving but reduces by one half the lifting or
lowering speed of the hook.
Some applications require that the load not move right or
left of the hoist centerline while being lifted. This is called
true vertical lift and requires that the hoist be double reeved.
Double reeving also requires less headroom than
single reeving.
FEQUEST MASTEFI CATALOG SECTION NO 30.2 FOA DETAILED INFOFMATION
Reeving changes hoist arrangement to the beam or track,
minimum headroom distance, and lateral hook travel.
HEADROOM: Some applications require that the distance
from the bottom ot beam to saddle of the hook be held to a
minimum. This dimension will determine whether a standard
or close headroom is required.

double (4PD) and are available in both parallel or cross
mou nted hoists.

\,
Common Types of WINCH Reevings
Work-rated winches can be reeved in various ways to gain
designed mechanical advantages. The illustrations on this
page demonstrate some of those advantages.
Winch reeving effects capacity, lifting distance, litting
speed and cable size. Winches are available in sinole and
double line arrangements.
The lead off angle is a critical specification in winch applications.
Standard lead off angles are shown below. For
the optional lead off angles indicated by the shaded areas,
the exact degree of the ang le or range of ang les is required
when ordering.
Standard Work-rated winches are supplied without wire
rope. When wire rope is supplied, it is 6 x 37 preformed, except
on applications that require non rotating, 18 x 7 construction
cable.
The swaged on drum end fittings of the wire rope are provided.
A vareity of "dead-end" fittings, such as swivel
hooks and load blocks, and idler sheaves, are available to
meet your specific application.

Glossary of Terms

ACM (Acceleration Control Module) A solid state electronic control that provides
gentle acceleration and deceleration of a hoist trolley or crane throughout the en.
tire operation cycle. ACM minimizes load pendulum swing more efficiently than
ballast resistors or f luid coupling by controlling acceleration up to 5 seconds after
start while providing full motor voltage for the whole cycle.
AGMA American Gear Manutacturers Association
ANSI American National Standard lnstitute
Ballast Resistors Inserted in the power lines to an induction motor, ballast
resistors control trolley acceleration for smoother starts by reducing the voltage
while starting; in turn reducing torque; increasing the motor acceleration time,
allowing the motor to come to speed smoothly. Ballast resistors are field adjustable.
CSA Canadian Standards Association
Contactors Electro-mechanical devices for establishing and interrupting an elec"
tric power circuit.
CMAA Crane Manufacturers Association of America
End Approach The minimum distance that a hoist can travel to the end of a crane
bridge or track without impacting a wall or some other obstruction. Cross
mounted hoists have a lower minimum end approach than standard parallel
mounted hoists.
Explosion Prool The property of an enclosure to contain internal sparking without
causing external hazard. Explosion proof hoists are used in operating environments
where flammable gases are present.
FPM (Feet per minute) The standard measurement of hoist litting speed, trolley
travel and crane bridge travel.
Headroom The distance from the bottom of the beam or monorail on which the
hoist travels to the bearing point of the load hook when the hook is raised to its
highest position. On a top running hoist, it is the distance from the operating tread
of the trolley wheels to the hook high position.
lmpact Loading The initial impact of the load that creates greater stress to the
block, wire rope, drum, hoist frame and the other load bearing parts of the hoist.
Inching Control Extra push buttons that permit small movements of the load hook
or hoist trolley through relays. The control can be adjusted to meet hook motion or
hoist movement requirements for particular applications.
Invertor A solid state electronic device that allows inf inite sDeed variation of electric
motors used in hoists, trolley motors and crane drives.
An invertor closely controls the frequency of the AC current; the motor gets only
enough current to supply the required torque for a specific speed. lt eliminates inefficient
and dangerous overheating resulting from unused electrical energy, a
common problem of many other infinitely variable speed control methods.
Limit Swiich Electro-mechanical devices that limit travel of the load block hook.
There are two types of limit switches: gravity type and geared type.
Gravity type limit switches use a weight, paddle or a lever thal when it contacts

the load block, trips a switch to the open position, that opens the raising circuit
that causes hoist contactors to open and breaks the power supplied to the motor.
Geared limit switches are driven by either the drum or gear reduction; a geared
limit switch operates on a definite ratio of drum revolutibns. lt is adjustable and
can be activated at any predetermined point of the hoist lift range, unlike ihe gravi.
ty switch which can only limit upper hook travel. In the event of the wire rooebverwrapping
or jumping the drum grooves through misapplication of the hoisl, the
geared limit switch is no longer synchronized and will not be activated when the
hook reaches its upper limit. For this reason geared limit switches should be used
with a gravity limit switch as a back.up.
MMA Monorail Manufacturers Association
Mainline Contactor A manually operated magnetic device that shuts off all power
to the hoist and crane motors in the event of a malfunction.
Mechanical Load Brake Part of the
gear train of the hoist, the load
brake serves as a back-up to the
electric motor brake. lt automatically
slows and controls lowering
speed and, if the motor brake fails, B,
holds the load while the motor or
motor brake is repaired or replaced.
A Weston type load brake (see il- Brake L nins
lustration) uses a brake gear with an
internal helical thread which mates
with and rotates on a threaded
shaft. Brake linings bonded on both
sides of a ratchet gear are engaged
by the screw actuated axial movement
of the brake gear along the
threaded shaft...to ihe teft toward
the brake gear again moves to the
left slowing lowering speed and
preventing the load overdriving the
hoist motor.

Motor Th€rmostal A bi-metallic, automatic reset thermostat is standard equipment
on all Wright hoists. lt is a thermally operated device that protects the hoist
motor from damage due to operating at a higher-than-normal current. Built into
the motor windings, it causes the motor control to be de.energized when the
temperature of the motor winding exceeds its predetermined limit.
NEMA National Electric Manufacturers Assocation
True Vertical Litt A lift without lateral hook movement. Requires that the hoist be
double reeved (see reeving section on page 20).
