A Liebherr LTM 1200-5.1 Crane. 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]
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 ...
The Lampson LTL-2600 or Transilift 2600 is a super-heavy mobile crane. With an ultimate load capability of over 2,600 short tons-force (2,400,000 kg f), it is among the largest land-based mobile crawler cranes in existence in terms of capacity. [4] It has a maximum boom length of 460 feet (140 m) and maximum jib length of 240 feet (73 m). [5]
Diesel-powered RTGs are notorious polluters at ports, as each burns up to 10 US gallons per hour (8.3 imp gal/h; 38 L/h) of diesel fuel. [3] There are also electric rubber tired gantry cranes. [4] The first electrified rubber-tyred gantry cranes (ERTG) in China was unveiled by the She Kou container terminal (SCT) in Shenzhen in Aug 2008.
The stability-limited rated load for a mobile crane supported on outriggers is 85% of the tipping load. These requirements, along with additional safety-related aspects of crane design, are established by the American Society of Mechanical Engineers in the volume ASME B30.5-2018 Mobile and Locomotive Cranes.
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.

The 2nd Auxiliary hook can be deployed to a water depth of 450 m. The two cranes are capable of a tandem lift of 14,000 tonnes. Each crane was fitted with 15,600 hp (11,630 kW) engines to power the boom and load hoists, 9 tugger lines and the crane slewing system. The cranes use 48 miles (77 km) of wire rope of various diameters.
