How to Select, Install, and Use Beam Clamps & Beam Trolleys

Posted by Beth Smith on 1/19/2018 to How To...
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 and Beam Trolleys

Beam ClampsBeam Clamp in Use
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 TrolleyPlain Beam Trolley in Use
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 TrolleyGeared Beam Trolley in Use
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
Unscrew the Jaws of the Beam Clamp
Open the jaws of the clamp, so that they are wide enough to fit over the beam flange.
Fit Jaw over Beam FlangeTighten Jaw over 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.
Installed Beam Clamp
Be sure that the beam flange is seated properly within the jaws before attaching any type of lifting devices or loads to the clamp.

Installation of Plain Beam and Geared Beam Trolleys

Measure the width of the runway beam.
Assemble Suspension PlateDimension between Trolley Flanges
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 Washers to Hanger Pin
Assemble the remaining washers to either side of the trolley side plates, and fit the nuts to the hanger pin.
Offset Pin for Geared Beam TrolleysOffset Pin for Geared Beam Trolleys
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.
Place Trolley on Beam
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 Nuts to Washers
Tighten the nuts against the washers.
Insert Safety Pin
Insert the safety pins that are provided.

I have two one ton beam clamps. I need to attach a Champion hoist to them. The hoist has two “upside down “u” fasteners” on the top. I have two heavy rated 4,000 lb. carabiners. Would it be safe to use the carabiners between the beam clamps to hold the hoist and lift 100-200 lbs. straight up (90 degrees)?

Shelly, It would seem that your working load limits are all within acceptable range to lift the load. But I think the upside down "U" fasteners are designed to mount to a small beam or square tubing. If you would mount a carabiner to the U fastener it may point load the fastener in a way in which it was not designed to handle and it may bend. It is always recommenced to use lifting fastening in the way they are intended. If you have any questions about your unique situation, you may want to contact a qualified person to evaluate your project on-site.
