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. Cranes capable of lifting six 20-foot containers have also been designed. Post-Panamax cranes weigh approximately 800–900 tonnes, while the newer-generation super-post-Panamax cranes can weigh 1,600–2,000 tonnes.
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 concept of a crawler crane undercarriage was first developed by the Bucyrus Company of South Milwaukee, Wisconsin in 1911. The first model, a Bucyrus gasoline-engine powered 'Type 14' dragline (usable with crane hook) had a standard 18.3m (60ft) lattice boom, a 4.27m (14ft) diameter swing ring and the crawler version weighed 47t (52USt).
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.
Ship-to-shore gantry cranes are imposing, multi-story structures prominent at most container terminals, used to load intermodal containers on and off container ships. They operate along two rails (waterside and landside designations) spaced based on the size of crane to be used. Ship-to-shore crane elements. Lateral movement system:
They also have a small footprint compared to gantry or Goliath cranes. The performance of super-heavy jib cranes is measured in tonne-metres, the product of weight and lifting radius, typically as much as 100,000 tonne-metres for large cranes. [8] Sarens offer a range of such cranes from 90,000 to 250,000 tonne-metres.

125 feet (38 m) long oversize load "Superload" The legal dimensions and weights vary between countries and regions within a country. [2] A vehicle which exceeds the legal dimensions usually requires a special permit which requires extra fees to be paid in order for the oversize/overweight vehicle to legally travel on the roadways.
