Принцип работы судостроительных кранов и способы предотвращения скольжения в дождливые дни.

Performance of shipyard crane: driving speed is lower than that of car type, higher than rail type, small turning radius, good off-road performance, uphill ability of 17% to 20%; tire gantry crane usually uses outriggers to lift weight, on flat ground You can work on all sides on the ground without using the outriggers, or you can walk slowly with a heavy weight on shipbuilding gantry crane. The stability performance is better.

How shipyard cranes work: Crane lifting principles. The elevation angle of the main arm is adjusted by a hydraulic cylinder, and the heavy object is lifted (released) by the hydraulic motor driving the drum with the wire rope, telescopic boom and hook. The principle of telescopic boom is that there is a rotating reel around a wire rope under the upper arm, and the wire rope pulls the upper arm out from the upper arm through a pulley on the top of the lower arm. When retracting, the drum is reversed to recover the wire rope, and the boom is retracted under its own weight.

Sevencrane shipbuilding gantry crane are generally used outdoors. If it rains, they are prone to slipping. In response to this situation, you may not know how to prevent it. How should tire-type cranes used outdoors prevent slipping? Next, the made in china shipbuilding gantry crane equipment manufacturer will share with you how to prevent skidding in rainy days.

In order to avoid operating difficulties or safety accidents caused by slippage, we first analyze the causes of slippage and then provide corresponding solutions.

1. Wheel pressure is too small
Correctly calculate the load capacity and wheel pressure carrying capacity of the industrial shipbuilding gantry crane for sale, and use anti-skid chains to fix the tires that are prone to slipping. This is to increase the friction between the tires and the ground, thereby reducing the chance of slipping.

2. The power of the selected motor is too large, and the driving force is greater than the friction between the wheels and the track.
Choose a matching motor, no matter how big or small it is.

3. The braking torque of the brake is too large and the braking time is too short.
The braking time should be appropriate.
We hereby remind everyone that for the sake of safety, automated shipbuilding gantry crane system operating in the open air should be stopped on rainy days and rain-proof measures should be taken. When the weather gets better, the rainwater must be removed during operation to keep the gantry crane in working condition to ensure that the lifting task can be completed safely and stably.
