Where are Electric Hoists Utilised
Electric hoists can be used in a huge variety of areas to aid in lifting and lowering heavy loads, they are commonly used on mobile gantry cranes and jib cranes. Some of the places that electric hoists are frequently used include industries such as; shipping, engineering, construction, warehouses, manufacturing, dockyards, car repair garages, and even the emergency services, these hoists are also used for more unusual applications, such as lowering chandeliers for cleaning, or lifting cars for displaying upright at big events, their possibilities are endless.
Electric hoists can be used on all types of cranes from smaller Jib and mobile gantry cranes to their larger equivalent versions and huge overhead cranes. They enable loads to be lifted, lowered and moved along the span of the crane with ease at the touch of a button.
There are many benefits to using an electric hoist, As all lifting procedures are considered high risk and the fact that health and safety is so predominant within the workplace the more the employer can do to minimise risks is fundamental to safe productivity; an electric hoist will greatly help. Not only do they make the lifting of large, heavy and awkward objects much easier and quicker they also alleviate potential strain and injury that a person may suffer if they try to lift loads of this nature. For these reasons they are a cost effective piece of lifting equipment; making loads quicker to lift & move, therefore saving time which equals money and vastly reducing the incidence of staff sick leave due to strains and injuries which can incur costs of sick pay and also reduced staffing levels which can have a major impact on production.
The majority of electric hoists have built in safety features; top and bottom hooks will have safety catches so the load will not become disengaged. Most will have a clutch system which slips at a preset torque, this is to prevent overloading the device; hoists will usually have safety cut out switches/emergency stop buttons for emergencies. Some models incorporate electro-magnetic spring brakes which will hold a load even if the power fails). Upper and lower limit switches may be present which can extend the life of the slip clutch, motor and gearbox.
How to use
Firstly the hoist itself will need to be fixed onto a suitable anchor point via its top hook, this is often a jib or mobile gantry crane or other suitable load bearing structures capable of taking the weight of the load to be lifted. Once the hoist is safely fixed into position then the chain may be lowered down from the hoist with the powered control unit and attached to the load to be lifted, this can be done in a variety of different ways depending on the size and type of load. It is often the case to use further accessories such as a lifting sling, either chain or webbing, as it is easier to attach these to the load at various points to ensure that the load will be evenly balanced and therefore not tip, ensuring a safer lift. Once you are sure the load is securely attached to the bottom hook of the hoist you may slowly begin your lift using the hand held remote control. You should always stop the lift for a moment once the load is just clear of the ground, (a test lift) to make sure the load is stable and secure before continuing, this procedure will minimise the risk of injury.
If your electric hoist is looked after then it should last a long time, any problems can usually be easily repaired, and a 6 or 12 monthly test and inspection should be carried out by a qualified engineer to certify its safety for use. These are all services that Cranes Direct can offer.
