Quality StandardsCrane Manufacturers Association of America (CMAA)ISO 9001:2008 certified EMH is a member of Crane Manufacturers Association of America (CMAA).EMH is certified to ISO 9001:2008 standards for design, manufacturing, installation, and servicing of overhead cranes. Hoist design conforms to all applicable national and local standard standards.You are dealing with an organization that continually reviews its management processes and meets internationally accepted standards.
6 to 1 Hoist Speed Ratio6 to 1 Hoist Speed Ratio The 6 to 1 ratio will provide better maneuverability, and using the slow speed can easily result in a fraction of an inch movement up or down. This will allow delicate positioning and precision spotting. In addition, the design is not load sensitive as the older variable speed control systems.
  • Lifting and lowering can be
    executed safely and precisely
  • Saves time
  • Reduces load damage.
Severe Demand Hoist MotorsSevere Demand Hoist Motors Our pole-changing squirrel cage hoist motors are designed and built for operations that require frequent inching and spotting. They are totally enclosed and fan cooled and designed exclusively for crane and hoist duty. These 60 minute TEFC “F” insulated motors efficiently dissipate heat. Large braking surface ensures fast, precise stopping of load under all load conditions.
  • Trouble Free Service
  • Longevity
Trolley Drive
(Single Girder Hoists)Trolley Drive		 Consists of pole-changing squirrel cage gear motor. Class “F” insulation. Integral DC disc brakes specially designed for crane service. Low torque, high inertia drives.Variable Frequency Drive standard.
  • Smooth acceleration without
    load swing.
  • Long, maintenance-free life.
Trolley Drive
(Double Girder Hoists)Trolley Drive D Hoist		 Consists of heavy duty pole-changing squirrel cage gear motor. Class “F” insulation. Integral DC disc brakes specially designed for crane service.Low torque, high inertia.Variable Frequency Drive standard.
  • Smooth acceleration without
    load swing.
  • Long, maintenance-free life.
Trolley Wheels
(Single Girder Hoists)Trolley Wheels		 Wide, large diameter, machine tool quality steel wheels and drive pinions.
  • Fit nearly any flange width or
    beam style.
  • Less flange bending stress
    reduces beam size.
Trolley Endtrucks
(Double Girder Hoists)Trolley Wheels		 Direct drive with rotating axle. Articulating endtruck. Sealed lifetime lubricated bearings. Hardened wheels.
  • Reduced maintenance.
  • More efficient power transmission.
  • Longer life.
  • Three-wheeling eliminated.
DC Rectified Disc BrakesDisc Brakes Our motor brakes are DC rectified magnet actuated disc brakes and are automatically applied in the event of a power failure. These self-compensating and virtually maintenance free brakes are provided with asbestos-free, non-polluting linings.
  • Operate millions of times
    without adjustment
  • Reduce service requirements
  • Provide longevity
Gear Trains and BearingsGear Trains and Bearings The gear train and bearings are lifetime lubricated and our gear trains are hardened and polished Class 12 helical gears. Our gear trains afford an extremely low decibel level during operation and the helical gearing is manufactured to exacting tolerances, resulting in exceptional longevity.
  • Relieve personnel from time
    consuming maintenance
    procedures
  • Years of trouble free operation
  • Meets or exceeds OSHA noise
    regulations.
Limit SwitchesLimit Switch All wire rope hoists are equipped with two upper and one lower geared limit switch. Easily adjustable, this switch brings the load to a positive stop in both hoisting and lowering directions.
  • Provide safe operation
  • Eliminate slack cable conditions
  • Prevent rope from unraveling
Wire Rope and Wire Rope GuideWire Rope Guide This assembly is of rugged design and able to withstand severe industrial use. It keeps the rope in contact with the drum grooves even under slack rope conditions.
  • Provides longer life
  • Requires less maintenance
  • Safer for operator
  • Reduces wear
  • Prevents rope from being
    unbraided and cut
  • Protects operator from injury
Quick Disconnect PlugsQuick Disonnect Plugs Pre-tested multi-pin plug and socket connections are used for motor power connections, pushbutton control cable, connections to control boxes and festooned terminations. The quick disconnects are of the highest quality, sealed from dust and moisture and vibration proof.
  • Save time
  • No electrician needed to
    disconnect components
Optional Overload LimitOptional Overload Limit Highly sensitive electro-mechanical overload device is a standard option. Prevents hoist from lifting loads larger than capacity.
  • Prevents damage to hoist
  • Provides longer life
  • Lessens maintenance
    requirements
  • Makes operation of hoist safer
