With a lifting capacity of 3,600 [5] to 4,000 tons, [6] a total boom length of 144 meters [3] and a total gross weight of 5,350 tons. [3] The XGC88000 crawler crane became the largest tracked mobile crane in the world, [ 7 ] [ 8 ] [ 9 ] beating out the previous record holder, the Liebherr LR 13000 when it officially came into production in 2013.
The Guinness World Records state that Taisun holds the world record for "heaviest weight lifted by crane", set on April 18, 2008 at 20,133 metric tonnes (44,385,667.25 lb) by lifting a barge, ballasted with water. [3] However, it was surpassed by the Honghai Crane when the new crane was completed in 2014, with a lift capacity at 22,000 tonnes. [5]
A modern container crane capable of lifting two 20-foot (6.1 m) long containers at once (end to end) under the telescopic spreader will generally have a rated lifting capacity of 65 tonnes. Some new cranes have a 120-tonne load capacity, enabling them to lift up to four 20-foot (6.1 m) or two 40-foot (12 m) containers.
The crane consists of two crawler modules, a boom/jig assembly, and a large counterweight composed of containers of local materials (typically earth or gravel). [9] The crane assembly is designed to be mobile, with pinned rather than welded modular construction , so it can be broken down and transported by a fleet of trucks.
Factory-calculated charts (or electronic safeguards) are used by crane operators to determine the maximum safe loads for stationary (outriggered) work as well as (on-rubber) loads and travelling speeds. Truck cranes range in lifting capacity from about 14.5 short tons (12.9 long tons; 13.2 t) to about 2,240 short tons (2,000 long tons; 2,032 t).
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 ...

A level-luffing crane is a crane mechanism where the hook remains at the same level while luffing: moving the jib up and down, so as to move the hook inwards and outwards relative to the base. [ 1 ] Usually the description is only applied to those with a luffing jib that have some additional mechanism applied to keep the hook level when luffing.
