Power drive kits for SPANCO gantry cranes provide high volume moving and lifting over a fixed travel route. Power drives can be used for travel on V-groove (inverted angle), ASCE crane rail or direct floor use on polyurethane tread wheels. T series gantries can be motorized either on V-groove or directly on the floor with polyurethane wheels. A series fixed height steel gantry cranes with an I-Beam span up to 15 feet can be motorized on a V-groove track only. The PF series gantry crane produces optimum design flexibility for motorized travel.

Features
Power drives for gantry cranes have a transfer capacity up to 15 tons. Power drives for gantry kits include two-drive assemblies with gear reducers, single speed 230/460V three phase TEFC motors and adjustable "soft-start" control.

Customization
An optional control panel is available for SPANCO power driven gantry cranes. It includes:

• Mainline magnetic power disconnect
• Reversing magnetic contactor
• Thermal overload
• 115V fused control transformer
• Branch circuit fusing to gantry crane motors
• Solid state adjustable “soft start” control adjustable for time and torque in a NEMA 3R enclosure

A power driven double leg trackless gantry with floor guides is 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 that 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 (semi gantry crane), top running end truck 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.
