Description

Technical Field

[0001] The utility model relates to the technical field of lifting, in particular to a lifting and lowering device for marine equipment. Background Art

[0002] In the field of shipping, the lifting of equipment is a crucial operation link. However, existing ship lifting devices generally have some significant problems.

[0003] In the prior art, common lifting devices are large in size. Large lifting devices may block passages, causing inconvenience to crew members on board. In some compact ship cabins, excessive size may also affect the normal layout of ventilation and lighting systems. Secondly, it is difficult to adjust the lifting height of existing lifting devices, which increases the difficulty of installation. Previous lifting devices also have deficiencies in operating accuracy and control, making it difficult to achieve precise height positioning and speed adjustment, which may cause the equipment to collide with the hull during the lifting process, causing damage to the equipment and the hull. Thirdly, common lifting devices have limited carrying capacity and cannot cope with heavier ship equipment. During the lifting process, overload is prone to occur, causing damage to the device and even causing safety accidents. To this end, we have a ship equipment lifting and lifting device to solve the above problems. Utility Model Content
