MAIN FEATURE
01
Interlocking shoe clearance balancing device and shoe auto-aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary, completely avoiding brake lining one side sticking to brake wheel.
02
At main hinge points where are equipped with self-lubricating bearings,which make higher efficiency of transmission and longer performance life.
03
The brake spring is arranged inside a square tube and a surveyor's rod is placed on one side. It is easy to read braking torque value and avoid measuring and computing.
04
Brake lining is of card-mounted and entirely shaped structure, which is easy and quick to replace. Brake lining of various materials such as semi-metal (non-asbestos) hard and half-hard, soft (include asbestos) substance are available for customer to choose
05
All adopt the company's new types of thruster as corollary equipment which work accurately and have long life.
ADDITIONAL DEVICES
YWL Series
The YWL series brake is two-step braking device. In the first braking step, a minor torque(adjustable within the prescribed limits) is applied to make stable deceleration braking. When mechanism stops, the second step starts. A bigger torque (adjustable within the prescribed limits) is applied to realize reliable maintenance or storm braking.The interval time between the two steps staring can be adjusted by one-way speed-adjusting valve in the circuit of damping cylinder according to actual requirements(adjusting range with 2~8s). The dimensions and braking torque parameters of this series brakes comply with JB/T6406-2006,JB/ZQ4388-86 standard(with A series), and DIN15435 standard. Thrusters equipped on them are Ed series thrusters which comply with DIN15430 standard.
YWLA Series
The YWLA series brake is a delayed braking device (the delay time can be adjusted within 2~8 seconds), with bigger braking torque. Its function is the same as YWL, but don't have the first step braking. Emergency braking electromagnetic valve can be installed if needed,which can realize emergency braking by handling it to make non-delay close when working machines are attacked by storm suddenly. The dimension and braking torque parameters of this series brakes comply with JB/T6406-2006 and DIN15435 standard, Ed series thrusters that comply with DIN15430 standard are adopted.
ADDITIONAL DEVICES
Hand released lever.
Wear-self-compensation device, which realizes endless self-compensation of shoe clearance and torque when lining wears.
Release (open) or close limit switch, which indicates whether brake is properly released or closed and provides interlocking protection.
Lining-wear limit switch, which indicates signals when wear of lining reaches the limit (Note: self-compensator should be equipped in application) and provides interlocking protection.
