Overview

There should be no obstruction when the rear shaft (wheel shaft, drum shaft, etc.) of the hydraulic direct acting brake rotates once. Prepare the test piece (steel billet) for load testing. According to the standards and specifications, the lifting weight for static load testing is 1.25 times the rated lifting weight, and the lifting weight for dynamic load testing is 1.1 times the rated lifting weight. So the test specimens to be prepared for the two overhead cranes are 100t, 88t, 50t, 44t, 25t, 22t, 12.5t, and 11t. All test specimens are provided by the owner.

Hydraulic direct acting brakeHydraulic direct acting brake

The connecting block of the piston rod is facing upwards. Horizontal installation: This installation method has the main parameter label facing upwards. However, it should be noted that regardless of the installation method used, the piston rod should not be subjected to any pressure, in order to improve the performance and prolong the lifespan of the thruster.

The brake chamber is initially filled with compressed air. Push out the push rod of the air chamber. The head of the push rod in the air chamber is located in the concave groove of the lever head. The push lever is transformed in the half moon bearing, and the cylindrical pin swings in the direction to push out the push rod. The piston and all push discs in the piston assembly move, and then the brake block on the caliper side is pushed towards the brake disc of the electric hydraulic thruster. At the same time, the cylindrical pin will be subjected to the reaction force of the push rod, which will cause the half moon bearing and half moon bearing seat to move to the left, and then move the clamp body, piston bracket, and clamp body bridge together.

Make the brake pads on the caliper bridge side approach the brake pads on the caliper bridge side under the propulsion of the caliper bridge. Under the combined action of the above two movements, the two brake pads can approach and press against the rapidly rotating brake disc closely following the wheel hub, generating a braking torque through the force between the brake pads and the brake disc. Previous: Precautions for Electric Hydraulic Pushers Next: Structure and Installation of Electric Hydraulic Pushers\\nThe electric hydraulic thruster produces abnormal noise and oscillation during operation, and the bearings should be checked for damage in a timely manner.

If damaged, it should be replaced in a timely manner; Next, check if the rotor is loose, and adjust it promptly if it is loose. When the thrust of the electric hydraulic thruster decreases, check if there is a lack of oil, and if there is a lack, make up for it in a timely manner; Is the voltage of the power grid lower than the additional voltage8If it is low, it should be promptly advanced to an additional value. Regularly check whether the electric hydraulic thruster is working properly, whether the oil is sufficient, whether there are any signs of leakage, whether the insulation of the introduced wires is outstanding, and whether the protective equipment is appropriate and reliable.

Check the oil every six months, and replace it promptly when the oil changes and viscosity increases. Related information: Electric hydraulic propulsion
