At the forefront of hoist technology - US made since 1905
For almost a century Detroit Hoist has designed and manufactured wire rope hoists. Many of the nation’s
leading companies were among it’s early users, relationships which in many cases continue to this day.
On-going research and development continues to yield remarkable innovations and provide the user with
more choices of a reliable and rugged machine to handle loads safely and economically into the next
century.
Mission Statement
Detroit Hoist is committed to providing top-quality, state-of-the-art hoists and crane components.
Customer satisfaction is paramount for our continued success and we are striving to be the best at what
we do and to deliver what we promise—on time and at competitive prices.
Product Support
Each hoist is delivered with operation– and maintenance instructions, parts lists and wiring diagrams. Most
spare parts for current– and past production models are available for immediate shipment from our central
warehouse in Michigan. Expert advice and authorized service location nearest you is available from our in-
house advisory service 800-521-9126 or e-mail service@detroithoist.com.
Load Tests & Inspection
Every Detroit hoist is load tested to 125% of rated capacity in accordance with HMI standards, inspected
and adjusted as necessary prior to delivery to ensure complete confidence and customer satisfaction.

Electric Hoists
Detroit hoists meet and exceed industry safety
standards. Each hoist is designed and
manufactured to meet or exceed HMI, H3/H4,
OSHA, ANSIand NEC standards for duty cycles
typical of general machine shops, fabrication and
warehousing.
Caution: Detroit Hoists products are not intended to
lift or transport human beings.
Many models and modifications are available to
suit individual operating conditions and
environments from standard indoor, to outdoor, to
hazardous environments. Value and reliability is
made possible through the use of time proven
serial components. Modular designs facilitate
customized solutions of specific applications at
reasonable cost.
A wide range of electric motors, control systems
and rope reeving methods result in an enormous
variety of capacities, hoist speeds and lifting
heights. Most models feature ‘true vertical lift’ as
standard. The table below shows but a few of all
available choices. Please contact us or a dealer
nearest you for assistance in selecting the right hoist for your operation.
Pneumatic Hoists
Most hoist models are also available with piston-type air operated motors and
controls and with spark resistant features for hazardous environments.

Mechanical Load Brake
The Detroit Hoist mechanical load brake is self adjusting and
serves as a secondary braking system to control, stop and hold
the load independent of the motor brake.
The brake features a sprag design with a minimum of 18 brake
elements for the smallest load brake size. The locking
mechanism is designed to last the lifetime of the hoist.
Motor Brake
DC rectified double sided disc brake, heavy duty brake coil, premium
asbestos free brake linings, for long life and low maintenance.
Hoist Motors
Heavy duty, cast iron frame, design D, class F
insulated, 60-minute rated motors are totally
enclosed, fan-cooled and provide protection
against vapors, dust and abrasives. Rated for
Class I, Division 2 hazardous areas. Built-in
thermal sensors guard against overheating.
Hoist Gearbox
Totally enclosed gear case with oil level sight glass, lifetime
lubricated gear train. Forged alloy gears, helical cut, no overhung
loads, no couplings, 3rd gear has splined output shaft to connect
directly to drum spline input. Designed to AGMA standards.
Options
Pole-changing motors 4/12 pole
Explosion proof motors
Air piston motors
Options
AC multi disc wet brake for severe applications.
Oil shear technology eliminates disc wear and
downtime due to brake maintenance.
Dynamic braking through frequency inverter
Options
For specific applications, this gearbox is
available without mechanical load
Options

Rope Reeving Components
Most of our hoists feature ‘true vertical lift’, i.e. the hook remains
centered at all times beneath the hoist. All sheaves are provided with
sealed bearings. The load block frame is a weldment with the hook
saddle secured by shear pins. Sheave covers are machined from
rugged castings. The hook rotates 360º on a thrust bearing and is
fitted with a safety latch.
Optional
rope guides ensure that ropes remain safely and
securely seated in drum grooves.
New: Rope Equalizer Pivot Lever System (Patent pending)
Ask for our special bulletin describing benefits of this system
for new and existing wire rope hoists.
Hoist Controls
NEMA 12 sheet metal enclosures to suit most indoor environments
are standard.
NEMA 4 or NEMA 7 enclosures are available for special
environments. Controls include reversing contactors, manual reset
circuit breakers, primary & secondary fuses for the control
transformer standard rated at 150VA. Speed timers are used on 2-
speed applications.
Options
Frequency inverters
Push button pendants
Radio remote control
Rope Drum
Rope drums are machined to accurate o.d. and grooved to
accommodate the full length of wire rope in one layer. Rope wedges
lock the rope securely into wedge pockets at rope termination points.
Drum diameters and groove depths meet the recommendation of HMI
and other international standards.
Drum spline connects directly to the gearbox output spline. Spline is
connection covered by lifetime warranty.
Options
Drum hardened for severe use or constant lifts in specific sectors.
Limit Switches
Photoelectric sensor automatically stops the hoisting motion when
the load block reaches its maximum safe operating height. Indicator
lights are visible to operator at shop floor level. Unlimited operations
and unaffected by wear this switch is superior to mechanical levers.
Options
Proximity limit switches for operational purposes.
Geared upper & lower limit switch.
