Each drive unit of the hoisting mechanism of a metallurgical crane should be equipped with two sets of brakes. This is to ensure that when lifting molten metal or other hazardous materials, sufficient braking capacity is provided to prevent accidents.
Types and Functions of Brakes
The hoisting mechanism of metallurgical cranes typically employs electric-hydraulic block brakes or hydraulic push-rod brakes. These brakes rely on the force of the main spring to actuate the brake arms, causing the brake bands to symmetrically engage the brake wheels, ensuring rapid and effective braking when required.
Maintenance and Inspection of Brakes
To ensure the normal operation and safety of brakes, regular inspection and maintenance are necessary. Common faults include oil contamination on the brake wheel and friction pads, burned-out electromagnet coils, and broken wires. Solving these problems usually requires cleaning the oil stains, replacing damaged parts, or adjusting the brake settings. Additionally, the contact area between the brake band and the brake wheel should be maintained at more than 75% of the brake band area, and a gap of 0.6 to 1.0 mm should be kept to accommodate the gradual wear of the brake band.
