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 ...
It is usually marked on the equipment by the manufacturer. It is a calculation of the Minimum Breaking Strength (MBS) also known as Minimum Breaking Load (MBL) divided by a safety factor, usually ranging from 4 to 6 on lifting equipment. The factor can be as high as 10:1 or 10 to 1, if the equipment poses a risk to a person's life.
A vehicle with a 5,000 lb (2,300 kg) capacity with the boom retracted may be able to safely lift as little as 400 lb (180 kg) with it fully extended at a low boom angle. The same machine with a 5,000 lb (2,300 kg) lift capacity with the boom retracted may be able to support as much as 10,000 lb (4,500 kg) with the boom raised to 70°.
Some floating cranes are mounted on pontoons, others are specialized crane barges with a lifting capacity exceeding 10,000 short tons (8,929 long tons; 9,072 t) and have been used to transport entire bridge sections.
The SLI measures the angle and extension of the boom along with the load weight and compares this with the manufacturer's specifications to determine if the lift is safe. [2] A safe load indicator has the capability of detecting the angle, weight of load lifted, and ground radius of any lifting device.
The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) are set of regulations created under the Health and Safety at Work etc. Act 1974 which came into force in Great Britain on 5 December 1998 [1] and replaced a number of other pieces of legislation which previously covered the use of lifting equipment.
The shear-leg crane on Left Coast Lifter has a 328-foot (100 m) long boom, weighing 992 short tons (900 t) with a 1,873-short-ton (1,699 t) lift capacity. [4] It is the largest barge crane ever used on the U.S. West Coast.
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 ...
