Steel Beam Attachments – clamps and Trolleys

Steel Beam Attachments – clamps and Trolleys
There are two main types of attachments which create a strong and very effective anchor point on a steel “H” beam; they are beam clamps and beam trolleys.
Beam clamps are a predominantly a stationary device although can be removed and re-positioned easily enough; a beam trolley, what is ed on the other hand is mobile, this web and can be moved back and forth across the beam, here either manually or powered, depending on the model.
Beam clamps attach to the beam by simply hooking around the steel beams flanges/projections; there will be some kind of tightening mechanism, like a threaded spindle, which will tighten up the jaws of the clamp around the flanges to provide a secure anchor point. An additional plus point to these beam clamps is that they can usually be adjusted to fit most sizes of steel beams/girders.
Beam trolleys come in three key categories, push travel, geared and powered. All types incorporate wheels, which sit on the flanges of the beam, secured with a threaded spindle, which enables them to be attached quickly and easily. Once fitted, the trolley can be moved precisely to any position along the length of the beam; push travel trolley’s are manually pushed to where required; geared trolley’s are moved by pulling down on a chain to move the gears and so move the trolley along the beam, and powered versions are electrically powered, and so will need a suitable electricity supply, and can be moved much easier, requiring no physical power.
Both beam clamps and trolleys provide secure anchor points from which to attach other hoisting equipment that will actually lift the load, such as a chain block or electric hoist. Clamps and trolley’s are frequently seen in use on Jib cranes, Mobile gantry systems, larger overhead cranes, and also in other areas, such as large buildings, where steel beams and girders are visible/accessible.
