Optional Control Panel

Selecting your power drive
Calculate the Maximum Load per End of Gantry (MLG) by using the formula:
MLG=P+H+G/2
P = Rated load capacity (1 ton = 2000 lb.)
H = Weight of hoist and trolley G = Weight of gantry
(All measures in pounds)
Compare the calculated MLG number with the MLG numbers on the chart. If your MLG number falls between two MLG chart numbers, choose the next higher chart number.
Example: 3-ton capacity PF Series gantry, model 3PF1520B P = 6,000 lb.
H = 900 lb. (use 15 % of rated load if hoist weight is not available) G = 1378 lb.
MLG = 6,000 + 900 + (1378)/2 = 7,589 lb.
In the example, you would select power drive part number 07101 for a V-groove track mounted assembly or part number 07202 for a trackless assembly.
Optional Control Panel - Includes mainline magnetic power disconnect, reversing magnetic contactor, thermal overload, 115V fused control transformer, branch circuit fusing to crane motors, and solid state adjustable "soft start" control adjustable for time and torque in a NEMA 3R enclosure.
(When control panel is ordered with power drive kit, a "soft start" will be wired in panel. If control panel is not ordered, "soft start" is supplied for wiring in customer's panel.)
Turn Key Systems - complete with controls and wiring are available.

Power Driven Double Leg Gantry

Power Driven Double Leg Trackless Gantry with Floor Guide ­ Ideal for applications requiring a gantry to run against a wall. A guide angle (supplied by others) lags to the floor along the wall guiding the gantry which travels directly on the floor on polyurethane wheels.
For trackless use in an open, clear area where a guide angle on the floor is not practical. A selector switch can be incorporated in the control pendant to selectively turn each motor on and off to compensate for skewing.

Single Leg Top Running End Truck

Single Leg, Top Running End Truck - The single leg design maximizes space utility in confined, narrow areas by traveling down an aisle on polyurethane wheels while the other end of the I-beam mounts on an end truck traveling on an overhead runway.

Single Leg Under Running End Truck

Single Leg, Under Running End Truck - A single leg gantry can also be used with an under running end truck on one end which travels on the bottom flange of an overhead runway beam.


Wide Flange Gantry Cranes
Wide Flange Gantry Crane

CUSTOM DESIGNED SINGLE OR DOUBLE LEG, WIDE FLANGE BEAM CONSTRUCTION GANTRIES with double flanged wheels for travel on ASCE rail or polyurethane wheels for direct floor travel.
Consider if your lifting application requires

  • Supplemental coverage for an overhead crane.
  • The facility floor remaining unaltered.
  • Wide clear passage for vehicles and/or personnel.

Custom designed solution
The general design of wide flange beam construction equips the end trucks with identical wheels and power drives ensuring

  • Smooth start-up.
  • Precise alignment for even wear on wheels.
  • Stable movement.

End truck design

  • Customize power and speed to meet your application.
  • Rotating axle design allows easy service of drive units.
Lower End Truck Guide Rollers

Lower end truck uses large diameter tread wheels. Rotating axle design Facilitates easy servicing of wheels, axles, and bearings.

Guide rollers and anti-kickup rollers securely align upper end truck against both sides of track flange.

Double flanged wheels

  • Meets higher duty service classifications to CMAA Class E, mill service.
  • Higher travel speed available for rail mounted cranes up to maximum 150 FPM.

Polyurethane wheels

  • Moderate duty service, CMAA Class C.
  • Maximum 80 FPM travel speed.
  • Maximum traction. Quiet, direct floor operation.
  • Facility floor remains unaltered.

Options

  • Multi-speed AC inverter drives.
  • Motor brakes.
  • Air drives.
  • Push-button station.
  • Warning lights, audible alarms, flood lights, or travel limit switches.
  • Top running or under running end trucks for single leg (semi-gantry) applications.
  • Design for severe environments or hazardous areas.
  • Special paint finishes.


Tripods
Tripods

TRIPODS
Quick, easy setup for heavy lifting in outdoor areas with no overhead support. Steel and aluminum construction capacities to two tons.

  • Independently, adjustable legs permit use on uneven ground and adjust on six inch centers.
  • Standard lashing kit, included with every tripod, prevents legs from spreading on hard or soft surfaces.
  • Free swiveling eyebolt hangs plumb to protect tripod head from twist and strain.
  • Aluminum feet are used on all hard surfaces. Standard on all models unless otherwise specified.
  • Mud feet are used on soft ground. Integral spikes firmly entrench legs to prevent slipping or sinking into ground. Complete interchangeability with aluminum feet and available in place of aluminum feet or as an optional accessory.
