Beam Clamp Or Beam Trolley?

Beam clamps and trolleys will be designed to fix onto a flanged steel beam

, like the kind you would probably see on a mobile lifting gantry, a Jib crane or an overhead crane. The key purpose of a beam clamp or trolley is usually to provide a strong and safe anchoring point from which to connect further types of lifting devices, like hoists, for example.

So what is the difference between a beam clamp and a trolley?

Firstly, a beam clamp is exactly as its name states; it is a clamp that locks onto a steel beam. A semi-permanent lifting accessory from which to hang a lifting appliance such as a chain block, hoist or maybe a lifting magnet. The beam clamp is classed as a semi permanent appliance since it is used in a predetermined position whilst under load and can not be moved, though when the load is removed the clamp is easy to remove and re-locate at a different place along the beam.You can find numerous variations of beam clamps that have differing fixing/clamping mechanisms, sizes and lifting capacities. Locking mechanisms are standard on most models and shackles are easy to attach to aid easy hanging of the lifting appliance. Beam clamps are very easy to install and are occasionally utilised in two's with a spreader beam but if used in this manner take care to make certain no one clamp exceeds the safe working load. With lifting capacities of up to 10000kg you can find a beam clamp appropriate for the majority of purposes.

A beam trolley similarly fits to the flange of a "H" beam and allows lifting machines to be fitted effortlessly; that's where the similarities end due to the fact that a trolley has steel wheels to enable them to travel over the beam. The basic trolley is manually pushed back and forth whilst a geared model will be transported more simply by pulling on a chain, subsequently there is the powered models which are the simplest to control through the use of remote/pendant control. The ball bearings enable smooth travel whilst the geared and powered models allow more exact positioning of the trolley, they may also be transported whilst under load so is a key benefit against the beam clamp, yet a locking mechanism can be added to lock it in place if necessary.

Basic safety precautions include ensuring the beam clamp or trolley are securely attached and remain secure at all times, inspecting ahead of and following every use. You should additionally guarantee that it's the correct size and capacity for the size and capacity of the beam. Neither a clamp or trolley should be utilised if the beam on which it will be fixed to is distorted, damaged or dirty (i.e covered with debris) in any way, this will be dangerous and severly influence the safe travel of a trolley.

In conclusion all types of beam clamps and trolley systems are indispensible to any business who has some type of crane or else perhaps beams in the roof of factories, this is because they enable the actual hoisting devices to be swiftly and easily attached in a safe and secure way, and with the extensive array of models and lifting capacities there should be something to suit most tasks.
