The role of safety brake design for foundry crane

The role of safety brake design for foundry crane: Foundry cranes are used in the metallurgical industry, and its task is to deliver molten steel for smelting furnaces. There are generally five major institutions: the main lift, deputy lift, cart, the main car, deputy car body.

The motor is mounted on a high speed shaft, the reel is mounted on a low speed shaft, and the high speed shaft and low speed shaft are connected together by a gear unit. The traditional hoisting mechanism brake is located on the high speed shaft, called the working brake. In this case, if a certain transmission link between the high-speed shaft and the low-speed shaft fails, the main hoisting brake will be ineffective for the reel. In this case, install the brake on the reel, called the safety brake. In the transmission link failure and speeding failure, run the brake first action, safety brake delay action. Ensure that the lifting of the liquid metal ladle can be protected in the event of an accident and safe and reliable braking.
