Marine crane provides great convenience for ship transportation, it also saves a lot of manpower, the operation of Marine crane must be trained professionals, and pay attention to safety rules, then how to operate safely? Today Xiaobian to give you points!

Marine crane lifts and moves items that need to be moved through circulation and intermittent movement, which greatly saves manpower and material resources and creates convenience for production and life. But as a mechanical device, of course, there is a lot to pay attention to. For example, in order to work more safely before using a Marine crane, it is necessary to look at the surrounding environmental conditions, mainly wind, temperature and lightning. Do not use when there is lightning and thunderstorms, and the wind speed is greater than 6. The ambient temperature is between -25°C and 60°C. In addition, before the work also need to pay attention to the requirements of hoisting wire ropes. When lifting goods, the Angle of the sling should not be too small or too large, the Angle should not exceed 120°, otherwise it is easy to break the sling due to excessive tension. If the Angle of the Marine crane is too small, the sling will be too long. Lifting work, if the inner arm elevation Angle is too large, easy to cause the system working pressure is too high!

In addition, when operating the Marine crane, it is important to note that the operator needs to have a clear understanding of the Marine crane to keep it in a highly efficient state. If you have any questions, please read the instructions in time. Or the operator needs to be trained before operation! Before starting the operation, ensure that the lifting devices (such as ropes, hooks, and lifting points) are safely designed and meet the requirements of lifting cargo weight and safety protection. For insurance purposes, please ensure that the goods are securely secured! The Marine crane shall not leave the system when it is loaded or in operation. In addition to these, another important point is that without the permission of the personnel, do not trespass into the operation and the scope of work. The two actuators of the Marine crane are strictly prohibited from operating at the same time. Of course, when in use, you also need to know the weight of the lifting load, can not exceed the load value of the ship crane calibration, can not lift the load with Angle (slope), can not drag the load. When the load leaves the ground, make sure there are no obstacles in the direction of the load! Or it is recommended that you use a rope to guide the load within a certain distance, no hanging! To understand the control valve on the hydraulic cylinder of the safety device, when the power loop hose fails, the control valve can still control the current position of the weight, and play the role of safety protection!

The above article content we tell you about the operation of the Marine crane precautions, if you do not understand then hurry to see. About this knowledge point to say so much, I hope it can help you.
