Any product that is utilised in the process of lifting, lowering or moving loads are broadly referred to as lifting gear, lifting equipment or lifting tackle.
All kinds of lifting gear are used either for safety reasons to protect personnel against injuries whilst lifting heavy loads otherwise for the reason that the item is just way too heavy for any person or persons to lift without help. All types of lifting gear should be regularly inspected and tested by a certified individual to guarantee the safety of the device.
Now we are going to look closer at the commonest lifting gear devices from little to big.
A shackle is a “U” shaped device made out of robust metal, they usually incorporate either a pin or a bolt used for safely locking on. Shackles are normally used as a connector to secure items together.
An eyebolt is a screw having a ring on the end as opposed to a screwdriver slot, they may be screwed into numerous surfaces to provide a securely fixed anchoring point to which further items could be attached too.
Ratchet lashings or load restraints are not just used daily by many lorry drivers but additionally by the general public, they are widely used for tying down and securing items, just like camping gear on a trailer, the webbing strap is threaded through a cam buckle which when pulled taut will hold the load securely but enables swift release of the load when needed.
There are many varieties of lifting slings available, from web slings, chain slings and even wire rope slings, all intended for different purposes, the softer webbing slings tend to be utilised for lifting more delicate or easily marked loads and chain slings for a tougher and much more versatile approach as they can be used in several combinations for different load types.
Pallet trucks are straightforward devices on heavy duty wheels that are widely used to allow the simple moving of large items from one place to another, whilst taking up little room, they are most frequently used in warehouses.
Sheet materials such as steel sheeting are lifted by way of either a plate clamp, utilised in two’s (often more) and clamp the fringe of the plate in its jaws, these may mark the steel, this is where lifting magnets come in, these tend not to scratch 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.
A beam clamp does precisely what it says, it clamps to a beam, often on a jib crane or mobile gantry providing a secure fixing point for added lifting devices. A beam trolley also fixes onto the projection of a beam to provide a fixing point, however incorporates wheels so the trolley can be moved across the beam, these are additionally obtainable in electrically powered versions for even easier moving.
Next we examine some larger lifting equipment products frequently used.
Ratchet lever hoists
Ratchet lever hoists are manually driven tools, attached to the load, the lever is raised then lowered and the chain moves across a ratchet system to raise and lower the load, they may be also used for tensioning and securing loads. Chain blocks or manual chain hoists are also a popular way of manually lifting loads and works by pulling on 1 chain to lift the load and the other side of the chain to lower the load.
Electric hoists are very popular as they supply an easy means of lifting heavy loads, many differing kinds can be found, suitable for various purposes and also lifting capacities. Most electric hoists use chain to lift but wire rope hoists are also obtainable. An additional powered hoist is the pneumatic air hoist working from an air supply and excellent where electric isn’t accessible or not suitable.
Mobile or lifting gantry cranes
Mobile or lifting gantry cranes provide a transportable framework to connect your lifting hoist too. A non-permanent device which can be moved on its castors to anywhere it may be required, these are usually manufactured to fit 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 can be swung or slewed around its vertical fixed column, up to 360 degrees depending on the type chosen.
An overhead crane is a much larger piece of lifting gear, frequently utilised in large manufacturing factories, high up within the ceiling space. They lift and move loads across a track by means of remote control and hoists. These are a fixed device so almost certainly not so versatile as the mobile gantry.
Finally we are able to conclude that there are many types of lifting gear products, all of which assist in the lifting, lowering and moving heavy, large or awkward loads. All of them assist in providing extra safety to the workforce and if serviced on a regular basis as necessary will work hard, last long and be a great investment.
