Product Information

Yes, there are cranes capable of lifting loads in the range of 800 tons or more. These are specialized heavy-lift cranes used in specific industries and projects. Yes, there are specialized cranes capable of lifting loads in the range of millions of pounds. These cranes are used for massive industrial and engineering projects. AIL vehicles are divided into 3 categories and must comply with these conditions to operate under STGO: vehicle with load width exceeding 3.5 metres, including any projections: 2 days’ notice to police and attendant required

With the onset of the Industrial Revolution the first modern cranes were installed at harbours for loading cargo. In 1838, the industrialist and businessman William Armstrong designed a water-powered hydraulic crane. His design used a ram in a closed cylinder that was forced down by a pressurized fluid entering the cylinder and a valve regulated the amount of fluid intake relative to the load on the crane. [41] This mechanism, the hydraulic jigger, then pulled on a chain to lift the load.

working days’ notice to highway and bridge authorities in relation to weight: the dimensions may need to be given to the police Engineering plant is taxable under the ‘special vehicle’ class (at the same rate as a basic goods vehicle ) if it meets the definition of mobile pumping vehicle, digging machine, or road roller. Other types of engineering plant are taxed under the heavy goods vehicle (HGV) rate, as if the machinery were a load carried on a goods vehicle, rather than being built into it. 3.4 Plating and testing maximum gross weight of 16,500 kgs multiplied by the number of axles: up to a maximum of 150,000 kgs Samson and Goliath (cranes) – two gantry cranes at the Harland & Wolff shipyard in Belfast built by Krupp – Goliath is 96m (315ft) tall, Samson is 106m (348ft) – span 140m (459ft), lift-height 70m (230ft), capacity 840 tonnes (830 long tons; 930 short tons) each, 1,600 tonnes (1,600 long tons; 1,800 short tons) combined

The size of an 80-ton crane can vary depending on the model and manufacturer. Generally, it will be a substantial crane with a high lifting capacity.

Tower and mobile cranes are used extensively on construction projects and present two principal hazards: For many centuries, power was supplied by the physical exertion of men or animals, although hoists in watermills and windmills could be driven by the harnessed natural power. The first mechanical power was provided by steam engines, the earliest steam crane being introduced in the 18th or 19th century, with many remaining in use well into the late 20th century. [1] Modern cranes usually use internal combustion engines or electric motors and hydraulic systems to provide a much greater lifting capability than was previously possible, although manual cranes are still utilized where the provision of power would be uneconomic. Drivers of engineering plant (as defined under the STGO regulations) don’t have to hold a vocational licence, and this class of vehicle can therefore be driven by the holder of a car driving licence (category B). 4.
