Hoisting is the process of lifting or lowering heavy loads whose weight is above the human physical capacity to bear, using the tools specifically designed for that task. "Hoist" is the general name for the category of devices used for vertical transportation of construction materials and personnel. Such devices had been employed for the needs of organized construction work since at least third millenium B.C. (even though the process had to wait a few more millenia before it was first introduced on the island currently known as Manhattan.)
The work of modern hoists (in New York as wel as everywere else) is based on the single mechanical principle of the flexible chain or rope wrapping dynamically around the rotating drum. The load is most typically attached to the chain, rope or wire rope via the lifting hook (even though in metalwork industry the cranes lifting heavy steel or iron objects may also use magnetic field for securing the load that is being lifted or lowered.)
Rope had been used by human beings since at least twenty six thousand years B.C. Tools for making rope have been first developed in Ancient Egypt no later than five thousand five hundred years ago. Since about that time, rope had become indispensable for securing and lifting heavy loads during construction process. Modern construction often employes ultra-strong nylon-based ropes. Average rope can serve up to five years, and must be regularly inspected for signs of damage before, and especially after that point.
Chain, compared to rope, is a much more recent invention: chains have been used in Europe starting from approximately 225 B.C. The unique feature of a chain is its flexibility: a chain, despite being made of metal, can be bent and even twisted. Chains used in construction must be inspected regularly, because a chain is only as strong as each of its links: a flaw in one link can lead to a fault of the entire chain.
Wire rope, usually made of steel wire, is fabricated in a way similar to how a regular rope is made. First the individual wires are twisted into a strand, and then several strands are twisted together around the core. Wire rope is used extensively in hoisting because of its safety: where flaws in chain links may lead to accidents, the multitude of wires twisted together easily compensate for a flaw in one or two of them.
Lifting hook is a massive metallic device that can hold a load using the load's own mass as the main force for securing it. Interestingly, lifting hooks not only can hold loads but, in many cases, also grab the load, thus allowing the initial very basic level of automatization. As a rule, lifting hooks are equipped with safety latches, meant to secure the load (and prevent its falling from a large height onto the crowded New York sidewalk). Lifting hooks often include pulleys as part of their construction.
There are two types of lifting medium used in all current hoisting machines: chain and wire rope. (Both types of lifting medium had been used in hoisting since early nineteenth century.) There are also two common power types employed in hoisting: electric motor and pneumatic motor. Four additional factors to be considered when deciding what type of hoist to purchase or rent for your construction needs are cost, durability, repairability and performance. Custom-built hoists tend to be considerably more expensive, but they last longer, are much easier to repair, and can handle much heavier loads while serving over longer periods of time. Integral-package hoists (non-custom hoists) tend to be more affordable and may present an excellent solution for smaller-scale projects. Please feel free to call our office in New York (718-389-9400), and our experts will be glad to help you to determine the kind of hoists you need for your specific construction project.
