Product Description

1) Brief review: Hydraulic active brake caliper is widely used for the emergency safety braking of the low-speed shaft of large and medium-sized cranes, port loading and unloading machinery hoisting and boom pitching mechanism. The working braking and emergency safety braking of mining winch, hoist and high-power inclined belt conveyor, the safety braking of the driving mechanism of cable car and cable crane, and the safety (emergency) braking of the low-speed shaft of the hoisting mechanism of special cranes such as casting cranes.

2) Cordial parts:

1) Shield

2) Brake base

3) Mounting bracket

4) Brake disc

5) Display switch

3) Essential characters:

Normally closed design, safe and reliable; Special disc spring applies force to brake and is hydraulically driven to release. (see the hydraulic station sample for the selection of hydraulic station).

Sensitive action and short closing (closing) time.

It can be equipped with opening limit switch and pad wear limit switch for interlocking protection and fault display.

High performance asbestos free hard friction pad, stable friction coefficient, no damage to brake disc and insensitive to water medium and salt spray (seawater).

Reasonable sealing structure design and imported nameplate seals have good effect and long service life.

Flexible installation position and simple use, adjustment and maintenance.

4) Working principle:

When the hydraulic power pack supplies pressure oil to the brake oil cylinder under the command of the control system, push the piston to move and further compress the disc spring. Under the traction of the brake arm driven by the oil cylinder, the brake pad disengages from the brake disc and the braking torque is eliminated;

5) Precautions during installation

When the hydraulic station is connected to the oil return channel under the control of the system command, the pressure oil returns to the oil tank of the hydraulic station under the action of the disc spring, the piston and piston rod move to the brake disc side, and the disc spring force in the oil cylinder is transmitted to the brake disc through the brake arm to produce the specified braking torque.

6) Basic parameters:
