Chain and lever hoist are most commonly used for applications that require a load to be lifted or suspended overhead. However, when load bearing beams are present, attaching the hoists to the beam can present a challenge, and that's where beam clamps and trolleys come into play. Watch our video for useful information on beam clamps and trolleys, and how you can safely install and put them to use for your application.

General Safety Information
Be sure to check the width of the beam before making your beam clamp or beam trolley selection.
Always take into consideration the load capacity of the beam and any other lifting devices used in your application.
Never attach a beam clamp or trolley to a beam that is fixed at an angle.
At E-Rigging, we offer 3 different options of Tyler Tool beam attachment products:
Beam clamps are fairly simple in design. They are composed of a set of jaws that open and close by the operation of a threaded handle. The jaws are designed to fit around and onto the flange of a beam. Once tightened to the beam, it will serve as a stationary attachment point for lifting or suspending devices.
Plain Beam Trolleys are designed to freely traverse the length of the beam flange it is attached to. It gives flexibility to the operator and allows the load to be easily moved from one place to the other with ease.
Geared Beam trolleys are essentially the same device as the plain trolley with one major exception. Geared beam trolleys feature wheels that are fitted with gears and chain. The trolley is designed so that when either side of the chain is pulled, the gears and wheels of the trolley will move back and forth along the beam flange, allowing the operator to more precisely move a load from one place to the other.
Installation of Beam Clamps
Open the jaws of the clamp, so that they are wide enough to fit over the beam flange.
Once the jaws of the clamp have fit over the beam flange, use the screw handle to tighten the clamp firmly onto the beam.
Be sure that the beam flange is seated properly within the jaws before attaching any type of lifting devices or loads to the clamp.
Measure the width of the runway beam.
Assemble the suspension plate and required number of spacer washers to the inside of the trolley side plates.The dimension between the trolley wheel flanges should be ¼” larger than the beam flange.
Assemble the remaining washers to either side of the trolley side plates, and fit the nuts to the hanger pin.
It is important to note that for geared beam trolleys, the hanger pin may need to be offset so it will not come into contact with the hand wheel. This can be accomplished by placing the required amount of washers to the hanger pin on both sides of the side plates.
With the trolley loosely assembled, spread the side plates allowing the trolley wheels to be placed over the beam flange, so that the trolley will properly sit on the beam.
Tighten the nuts against the washers.
Insert the safety pins that are provided.
