Marine Fixed Boom Crane
Marine Fixed Boom Crane
Application
A marine fixed boom crane is a type of crane that is used in marine environments, such as on ships, offshore oil rigs, or ports. As the name suggests, it has a fixed or stationary boom, which means that it cannot be moved or adjusted during operation. These cranes are typically used for lifting and moving heavy objects, such as shipping containers, large equipment, and other materials, both on and off ships. They are designed to withstand harsh marine environments, such as strong winds, heavy waves, and saltwater exposure.

Repair and maintenance advice
Regular inspection, maintenance and management The lifting machinery users should always check and maintain the lifting machinery in use, and formulate a regular inspection management system, including daily inspection, weekly inspection, monthly inspection, annual inspection, and dynamic monitoring of cranes. Any abnormal situation can be found at any time and dealt with in time, so as to ensure the safe operation of the hoisting machinery.
(1) Daily inspection
The routine maintenance items that the driver is responsible for are cleaning and sanitation, lubricating the transmission parts, adjusting and tightening. The sensitivity and reliability of the safety device are tested by running, and whether there is any abnormal sound during operation.
(2) Weekly inspection
It is jointly carried out by the maintenance worker and the driver. In addition to the daily inspection items, the main contents are the appearance inspection, the safety state of the hook, the pick-up device, the wire rope, etc., the sensitivity and reliability of the brake, clutch, and emergency alarm device. Observe the transmission parts for abnormal noise and overheating.
(3) Monthly inspection
The inspection is organized by the equipment safety management department and carried out together with the relevant personnel of the user department. In addition to the weekly inspection content, the state inspection of the power system, hoisting mechanism, slewing mechanism, operating mechanism and hydraulic system of the hoisting machinery is mainly carried out. For the electrical control system, check whether the feeder, controller, overload protection and safety protection device are reliable. Check the failure symptoms caused by the leakage, excitation, temperature, vibration, noise and other reasons of the lifting machinery through the test operation. After observation, the structure, support and transmission parts of the crane are subject to subjective inspection under the state, so as to understand and grasp the technical state of the whole crane, and check and determine the fault source of the abnormal phenomenon.
(4) Annual inspection
The leader of the unit will organize the equipment safety management department to take the lead and jointly carry out with the relevant departments. In addition to the monthly inspection items, the technical parameter testing and reliability test of the hoisting machinery are mainly carried out. The wear and tear of the metal structure, the welding seam of the metal structure, the test flaw detection, and the test of the safety device and components are used to evaluate the technical status of the operation of the lifting equipment. Schedule major repairs, renovations, and renovations.
