Suspension (Hook type or Rigid mounted): Hook mounted may be used with any hoist hook mounted hoist. Rigid mounted are used with lug-mounted hoist (hand hoist, electric or air hoist) to conserve headroom they are mounted directly to the hoist.
Types of Beam: The two most popular styles are American Standard & Wide Flange types which use the standard universal ball tread wheel
Beam Size : Must be considered for the trolley adjustment based on the beam size
Type of Trolley: Push pull, hand geared, or motorized
Minimum Curve Radius: The trolley wheel tread (which rests on the beam) must be able to run smoothly and negotiate along the tightest curve of the beam
Headroom: Measured from the bottom of the treads on the wheels to the mount point where you intend to hang the trolley from
Trolley Speed: Motorized trolleys are offered in standard and special speed configurations and are rated in feet per minute (fpm) of travel. Increases versatility of hoist
CAUTION: This equipment is intended for industrial use only and should NOT be used to lift, support, or otherwise transport people, or to suspend loads over people.
