Commonly asked questions regarding the beam clamp and beam trolley will be clarified within this article.

Beam clamps and trolleys will be intended to mount onto a flanged steel beam, such as the kind you would likely observe on a mobile lifting gantry, a Jib crane or else an overhead crane. The key aim of a beam clamp or trolley is to provide a robust and safe fixing point from which to add additional kinds of lifting equipment, like hoists, for example.

So what is the distinction concerning a beam clamp and a trolley?

A beam clamp can be described as a piece of equipment that clamps onto a beam and stays in that position whilst a load is being lifted by means of a lifting appliance, though they are able to be removed and re-located, but not whilst under load. A beam clamp is classed as a semi-permanent tool which is frequently obtainable in various model types; different sizes can be found to fit differing sizes of steel beams, although you can find also adjustable versions available too. Some clamps will have a scissor type action, several will have bolt fixings and many may encompass a screw lock type of fitting. The majority of kinds of beam clamp will include a locking device to make sure it is locked securely onto the beam; they are also usually supplied with a shackle already attached to facilitate even quicker attachment of other lifting equipment. Particular varieties of these clamps are extra robust and will include extra toughened side plates and jaws for those demanding jobs. Regularly obtainable in lifting capacities up to 10000kg the beam clamp provides a lightweight, easy to install lifting point from which to suspend your preferred lifting device.

Beam clamps
may also be used in two's but a spreader beam is generally used for this arrangement and care taken, to ensure that no single clamp exceeds its maximum lifting capacity, loading in line with the centre of gravity is particularly essential here.

A trolley also attaches onto the projection/lip of a steel beam, however they move along on small wheels so that they may move backwards and forwards along the length of the beam, trolleys come in 3 varieties, either push travel, where they are manually pushed over the beam, a geared trolley where they are able to be easily operated by pulling a chain to manoeuvre back and forth with minimal effort, or else a powered model, operated by handheld remote control, all kinds may be transported even when loaded. A beam trolley is therefore a mobile anchoring point intended for attaching other lifting equipment such as a hoist. The machined steel wheels on these trolley systems enable it to be effortlessly traversed across the beam, especially the geared and powered versions, where the wheel s are fitted onto encapsulated and lubricated, ball bearings; they also enable exact positioning of the trolley and therefore the load. Beam trolleys, frequently observed on cranes are obtainable in a wide choice of models and capacities, often up to 20000kg. As a trolley is designed to travel back and forth across a beam, locking devices are able to be fitted to secure it into a chosen spot if desired.

For safety’s sake it's always vital to guarantee that the clamp or trolley is the right dimension for the beam and also of the appropriate capacity for the object to be lifted. You need to always make sure they are firmly fixed to the beam prior to each use and should by no means be used on damaged or distorted steel beams. Evidently you should on no account exceed the safe working load and you must also ensure the beam itself is capable of taking the weight of the load and appliances utilised.

The bulk of cranes of any variety use some form of beam clamp or trolley system due to the fact that they have steel "H" beams. Both are uncomplicated to mount and maintain and supply safe and secure fixing points for all additional lifting devices, like electric hoists, chain blocks, lifting magnets, ratchet lever hoists and wire rope winches etc.
