A girder clamp is a heavy-duty lifting accessory that securely attaches hoists, trolleys and lifting equipment to steel beams. It provides a strong and stable anchor point for safe lifting, suspension and movement of heavy loads in construction, industrial and warehouse settings. Common uses include hoist attachment and load suspension. 

Yes, most girder clamps are adjustable to fit various beam widths using adjustable jaws or screw mechanisms. Simply loosen the adjustment, position the clamp, slide the jaws to the correct width and tighten securely. Always check load capacity and beam compatibility.

A girder clamp and a girder trolley both attach to steel beams but serve different purposes. A girder clamp is a fixed anchor that securely attaches hoists, slings or lifting equipment to the beam, holding loads in place without movement. A girder trolley is movable, allowing horizontal load movement along the beam, and can be manual or chain operated. The key difference is the girder clamp is stationary, while the girder trolley enables movement.
