The factor can be as high as 10:1 or 10 to 1, if the equipment poses a risk to a person's life. Working Load Limit ( WLL ) is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield.
The XGC88000 crawler crane, unlike the majority of crawler cranes, comes in two sections. The primary section consists of the crane itself, which boasts a maximum boom length of 144 meters, a maximum total length of 173 meters (including the counterweight radius), a maximum height (when fully erect) of 108 meters, a lifting capacity ranging between 3,600 and 4,000 tons [10] [11] [12] (although ...
In 2016 ESTA (the European Association of Abnormal Load Transport and Mobile Cranes) published the first SPMT best practice guide [10] to help address the problem of trailers occasionally tipping over, which happened even when the operating rules and stability calculations had been precisely followed.
Greco-Roman Trispastos ("Three-pulley-crane"), a simple crane type (150 kg load) A crane for lifting heavy loads was developed by the Ancient Greeks in the late 6th century BC. [7] The archaeological record shows that no later than c. 515 BC distinctive cuttings for both lifting tongs and lewis irons begin to appear on stone blocks of Greek ...
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap. A hoist, the lifting component of a crane, travels along the bridge.

A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models. [1] They are designed to easily transport [2] to a site and use with different types of load and cargo with little or no setup or assembly.
