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 ...
A Safe Load Indicator (SLI) or an Automatic Safe Load Indicator (ASLI) is a device which is installed on mobile or portal cranes to alert the operator if the lift is exceeding the safe operating range of the machinery. [1] In some cases, the device will physically lock the machinery in circumstances it determines to be unsafe.

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 ...
Logo of the Crane Manufacturers Association of America. The Crane Manufacturers Association of America, Inc. (CMAA) is an independent trade association in the United States.

The Military Load Classification (MLC) is a system of standards used by NATO to classify the safe amount of load a surface can withstand. Load-carrying capacity is shown in whole numbers for vehicles, bridges, roads, and routes. Vehicles are classified by weight, type, and effect on routes.
It accounts for the dynamic effects that can increase the load on a crane's structure and components during lifting operations. These effects include: Hoisting acceleration and deceleration of the load, which is a significant factor; Crane movement such as slewing or luffing; Load swinging; Wind forces acting on the crane, the load and the ...
Lifting equipment can be assigned a Working Load Limit (WLL) in the interests of avoiding failure; Working Load Limit is calculated by dividing the Minimum Breaking Load of the equipment by a safety factor. [5] WLL as a concept is not restricted to lifting, being also relevant for mooring ropes. [6]
