Requirements related to the installation of disc brakes on cranes
Thread Content
The brick-type brake is a common type of brake used in cranes. When installing this type of brake in a crane, the following requirements must be met: 1. Cleanliness. All the pins of the Wazh axis brakes, as well as the parts of the crane that are to be assembled, should be cleaned thoroughly before actual assembly, to ensure that the hole diameters are unobstructed and that the pins can rotate smoothly. 2. Assembly deviation. For each component of the tile-type brake installed on the crane, there is a specified maximum allowable installation tolerance; these include: a. The horizontal deviation between the centers of the two brake pads on the same brake wheel ≤ 2 mm ； b. The deviations in both the horizontal distance and the vertical distance between the axis of each pin in the gate seat and the axis of the main shaft, as measured in the vertical plane, should be kept within the range of ±1mm ； 3. Assembly clearance. When a brick-type brake is installed on a crane, it should be ensured that the rivets of the brake shoes are 2 mm lower than the surface of the brake pads, the gap between the brake beam and the rope stop plate is <5 mm, and the gap between the brake shoes when they are not pressed together is ≤2 mm. 4. Braking pressure. After assembly, for those equipped with hydraulic or pneumatic braking, it is also necessary to ensure that the braking pressure of the disc brake does not drop by more than 0.196 MPa within 10 minutes after reaching the rated pressure.
