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 switch3) 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:
* Product model: SB50, SB100, SB160, SB250, SB315, SB400,
SB500; * Applicable disc diameter: ≥ Ø 500 Ø 600, ≥ Ø
1200 Ø 1800mm; * Braking force: 50kn-500kn.
