Description

Technical Field

[0001] The utility model relates to the technical field of hoisting and transporting, in particular to a special hoisting device suitable for offshore construction. Background Art

[0002] Lifting equipment is a type of mechanical equipment used to lift, move, suspend and install heavy objects. They are mainly used for lifting operations in construction sites, factories, ports, ships and other places.

[0003] Offshore construction faces an extremely complex and volatile environment. Waves are constant and irregular, varying in height and frequency, causing the construction platform to oscillate and rock side to side, impacting the lifting equipment mounted on it. In deep waters, wave energy is greater, significantly impacting equipment stability. For example, during the offshore construction of large cross-sea bridges, waves several meters high can impact the construction platform, causing the lifting equipment to shake violently. Variable sea breezes exert lateral force on the lifting equipment, causing it to tilt and shake. Ocean currents vary in speed and direction, exerting lateral force on the construction platform and lifting equipment, exacerbating the shaking.
