The NIOSH lifting equation is a tool (now application) that can be used by health and safety professionals to assess employees who are exposed to manual lifting or handling of materials. [7] The NIOSH lifting equation is a mathematical calculation which calculates the Recommended Weight Limit (RWL) using a series of tables, variables, and ...
The National Institute of Occupational Safety and Health (NIOSH) lifting equation (1994) [1] provides guidelines for evaluating two-handed manual lifting tasks. It defines a Recommended Weight Limit (RWL) as the weight of the load that nearly all healthy workers can lift over a substantial period of time (e.g., eight hours) without an increased ...
Lifting equipment, also known as lifting gear, is a general term for any equipment that can be used to lift and lower loads. [1] Types of lifting equipment include heavy machinery such as the patient lift , overhead cranes , forklifts , jacks , building cradles, and passenger lifts, and can also include smaller accessories such as chains ...
In addition to the motions of lifting and revolving, there is provided a so-called "racking" motion, by which the lifting trolley, with the load suspended, can be moved in and out along the jib without altering the level of the load. Such horizontal movement of the load is a marked feature of later crane design. [73]
The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and causes less wear and tear on the lifting machine. [2] Counterweights are often used in traction lifts (elevators), cranes and funfair rides. In these applications, the expected load multiplied by the distance that load will be spaced ...

A crane's rated load is its Safe Working Load (SWL) and the design load (DL) is, (p 90) [1] = The dynamic lift factor for offshore cranes in the range 10 kN < SWL ≤ 2500 kN is not less than =.(p 84) [1] Thus for a crane with a SWL of 2000 kN (~200 tonne) its design load is not less than, = = The minimum breaking load (MBL) for the combined capacity of reeves of a steel wire hoisting rope ...
