EMH Endtrucks
EMH endtrucks are high quality components, designed for reliability and economy. The steel structure of the endtruck is a torsion-resistant box girder, prepared to be connected to the crane girder. Precise machining and exact alignment of the crane girder mounting plates ensure unsurpassed travel characteristics and long life.
Key features of EMH Endtrucks:
- Direct driven, precision-splined shaft-to-gear connection
- Lifetime lubricated, totally enclosed gear trains
- Spheroidal graphite cast or forged steel wheels
- Inertia fly wheel (for two-speed drive) delivers soft start and smooth speed transition.
- 60 minute, "TEFC" motors with Class "F" insulation.
- DC rectified brakes
- Optional Quick Disconnect Plugs at all motor connections for easy installation and service
- Single, two-speed or Variable Frequency Drive controls available as standard

Features and Benefits of EMH Endtrucks
| Feature |
Advantage |
Benefits |
Drive Motors
|
Single speed squirrel cage design
Variable Frequency Drive (inverter) controls
Direct drive system
Class F insulation
Large surface cooling fins for excellent heat dissipation. |
- Reliable, economical
- Infinitely variable speed
- No open gears, pinions or
couplings to lubricate
- Extended motor life
|
Drive Wheels
|
Both the bridge and trolley wheels are rolled or forged steel. Wheels are hardened to protect both the runway rails and the wheels from wear.
Our wheel design is unlike any other in the industry. Simple yet rugged, it allows quick and easy wheel removal without special tools. There is no axle to undress. |
- Years of trouble free service
- Long life and high overload
capacity
- No special tools or technicians
required for wheel removal
- Smooth and quiet operating
characteristics with the high
dampening effect of cast wheels
|
Endtruck/Girder
Connection
|
Attaches the end of the girder to a side
mounting plate on the endtruck.
Friction type connection
Utilizes high quality mounting bolts torqued
to 410 ft-lbs.
Simplified installation process |
- Excellent stability in horizontal
and vertical planes
- Smooth crane movement,
without binding or skewing
- Better crane alignment, leading
to less wear and tear on wheels
and runway
- Less chance of installation error
|
Bridge Brake
|
DC rectified, magnet-actuated disc brake is
automatically applied in the event of power
failure.
Brake is self-adjusting. |
- Increases operator safety,
prevents damage to loads.
- Virtually no maintenance
needed. |
Quick Disconnect Plugs
|
Pre-tested multi-pin plug and socket
connections are used.
Asymmetrical design means plugs can only
be connected one way.
Connections are finger safe.
The quick disconnects are of the highest
quality, sealed from dust and moisture and
vibration proof. |
- Save time
- Pole reversal impossible.
- Increased safety for installers
and maintenance personnel.
- No electrician needed to
disconnect components
|
Bridge Controls
|
Inherent "soft" start minimizes mechanical
shock loading and wear of the drive
components.
Elimination of high starting currents reduces electrical operation costs and motor temperatures.
Smooth, precise motion control.
Electronic dynamic braking
No motor direction contactors
Ability to "reverse plug" and "jog without
damaging motors and drives.
|
- Trouble free service
- Longevity
- High productivity
- Reduced damage to loads
- Almost no brake wear and/or
maintenance
- Reduces the number of
breakdowns due to operator
error
|
Bumpers
|
Polyamid bumpers at both ends absorb
energy. |
- Prevent damage to crane
- Meet OSHA safety requirements
