UM - SINGLE GIRDER UNDERHUNG MOTORIZED END TRUCKS
|
|
For heavy-duty class "C" single girder crane applications, underhung motorized
end trucks combine superior performance with underhung space savings. |
|
Along with a full range of features, end truck kits include: two trucks; two sealed, totally
enclosed, non-ventilated (TENV) motors with adjustable DC brakes; two helical gear
reducers; rubber bumpers; and bridge beam fastener set. All trucks are fully painted. Bridge
fabrication prints are also included. As a member of the Crane Manufacturers Association
of America (CMAA), we build UM trucks to meet current industry and regulatory codes. |
|
|
|
|
| Benefits to count on: |
|
|
 |
|
|
|
 Frames fabricated from MC channel
provide superior strength, rigidity and
structural integrity. |
|
|
|
|
Reduced wheel friction due to heavy-duty
side guide rollers results in smooth crane
travel—guide rollers are 3 1/2" O.D. with
fixed steel axles. |
|
|
|
|
Dual tread wheels for use on S or W shaped
runway beams—each wheel fitted with 2
deep groove ball bearings, meeting L10
bearing life criteria for class C cranes. |
|
|
|
|
Runway flange widths up to 6" standard,
with wider ranges also available
(trucks for patented track available). |
|
|
|
|
Minimize assembly labor with fully machined frames—girder connection, bracing and collector mounting bracket
holes are pre-drilled for easy installation. |
|
Purchase the right component for the job—dedicated models for capacities of 2, 3, and 5 Ton, with maximum
span increments of 35' or 50'. |
|
| Sealed TENV drives with quiet, smooth–operating helical gear reducers. |
|
| Drives are designed for crane service, with 30 minute rating and feature cooling fins for efficient heat dissipation. |
|
| Thermal motor protection is standard. |
|
| Externally adjustable DC brakes allow controlled deceleration—adjustable up to 50% of rated motor torque. |
|
Drives and brakes are compatible with Electronic Acceleration Control (EAC) and Variable Frequency Drive
(VFD). |
|
| Drives are connectable for 230/460V-3-60 (including dual speed models). Other voltages available. |
|
| Rail sweeps and drop stops are standard. |
|
| Longer or shorter end truck lengths are available — consult us. |

UG—Single Girder Underhung Geared End Trucks
|
|
UG end trucks provide similar benefits to the UM truck, but with geared drive. Along with many important features,
end truck kits include: two trucks; hand wheel drive; shaft couplers; appropriate drive shaft bearing supports based
on span; rubber bumpers; and bridge beam fastener set. All trucks are fully painted. Bridge fabrication prints are
also included. As a member of Crane Manufacturers Association of America (CMAA), we build UG trucks to
meet current industry and regulatory codes. |
|
|
|
| Benefits to count on: |
|
 |
|
|
Versatile design allows hand chain wheel placement
anywhere on drive shaft based on application needs.
Upgrade easily to UM series by simply adding drives
and reducers.
Ideal for precision spotting requirements where motorized
operation is not necessary.
Longer or shorter end truck lengths are available -
consult us.
Suitable for use on S or W shaped runway beams. |
|
|
|
UP—Single Girder Underhung Push End Trucks
|
|
|
UP end trucks provide similar benefits to the UM underhung motorized truck, but for push operation. Along with
many important features, end truck kits include: two trucks; rubber bumpers; and bridge beam fastener set. All
trucks are fully painted. Bridge fabrication prints are also included. As a member of CMAA, we build UP trucks
to meet current industry and regulatory codes.
|
|
|
|
| Benefits to count on: |
|
 |
Compared to flanged wheel trucks, UP trucks with guide
rollers operate easily, particularly in long span or long lift
applications.
Upgrade easily to underhung geared UG or motorized
UM models - frames are fully machined and prepared
for conversion.
Longer or shorter end truck lengths are available -
consult us.
Suitable for use on S or W shaped runway beams. |
