This publication will take a brief look into the most typical varieties of lifting equipment that are used every day within a wide range of industries, and also will incorporate information on how and where they might be used.

Any product which is used in the process of lifting, lowering or moving loads are broadly known as lifting gear, lifting equipment or lifting tackle.

All sorts of lifting gear are widely used either for safety reasons to guard personnel from injury whilst lifting weighty loads or for the reason that the object is just way too heavy for any person or persons to pick up unaided. All types of lifting gear needs to be regularly inspected and tested by a qualified person to guarantee the safety of the device.

Next we examine the basics of small and large

lifting equipment.

Shackles are manufactured from strong metal and take the form of a U shape; used as a type of connecting gadget between 2 items, a shackle will possess a bolt or pin to provide its locking device and so ensuring a secure hold.

An eyebolt is a screw with a ring on the end as opposed to a screwdriver slot, they may be screwed into numerous surfaces to deliver a secure fixed anchoring point to which further items can be anchored too.

Ratchet lashings or load restraints are not just used daily by many lorry drivers but in addition by the general public, they are used for tying down and securing objects, for example camping gear on a trailer, the webbing strap is threaded through a cam buckle which when pulled taut will hold the load securely yet permits rapid release of the load when needed.

There are many types of lifting slings available, from web slings, chain slings and also wire rope slings, all used for different purposes, the softer webbing slings are often used for lifting more delicate or easily marked objects and chain slings for a tougher and much more adaptable approach since they can be used in several combinations for various load types.

Pallet trucks are straightforward devices on heavy duty wheels which are widely used to allow the simple moving of large items from one place to another, whilst taking up little space, these are most frequently utilised in warehouses.

Sheet materials such as steel sheeting are lifted by means of either a plate clamp, used in two's (often more) and clamp the edge of the plate in its jaws, these may mark the steel, this is where lifting magnets come in, these tend not to mark the steel plate as they use a magnetic force to lift, however they'll only work with ferro-magnetic materials, and precise lifting conditions will apply for a safe lift.

Beam clamps and trolleys are tools which fix onto the flange of a beam on a mobile or jib crane for example. A beam clamp stays in a set position where as a trolley can be manually moved along the beam, or via of a remote device if it is a powered trolley. These devices provide a secure fixing point to enable additional products to be fitted for lifting, for instance a hoist.

Now we move on to larger types of lifting gear.

A ratchet lever hoist lifts loads by the use of a ratchet mechanism, powered manually by moving the lever back and forth, they could be used for tensioning in varying directions. A manual chain hoist/chain block are one of the most often used pieces of manual lifting gear, lifting and lowering loads by way of pulling on a chain.

There are different types of powered lifting devices, all are fitted to some structure/beam/crane of some kind, the most commonly utilised is the electric hoist, similar to the chain block but electrically powered and therefore able to lift heavier loads. Electric wire rope hoists are also available as are air hoists working on a pneumatic air supply.

Mobile or lifting gantry cranes provide a portable framework to connect your lifting hoist too. A non-permanent device that may be moved on its castors to anywhere it may be needed, these can be made to suit your size and lifting capacity needs, and consist of 2 A shape end frames which has a H beam across the top. This is a very popular piece of lifting gear.

A Jib Crane is a semi permanent device which is extremely popular in both large and small industries. The jib cranes arm may be swung or slewed about its vertical fixed column, up to 360 degrees depending on the type chosen.

An overhead crane is a much bigger piece of lifting gear, commonly utilised in large engineering factories, high up within the ceiling space. They lift and move loads across a track by means of remote control and hoists. They are a fixed piece of equipment so probably not so adaptable as the mobile gantry.

In conclusion then we can see that there are numerous varieties of lifting equipment devices to aid in handling heavy loads, though this short article has merely scratched the surface of the key varieties.
