2.Application:
Electro-hydraulic Drum Brakes can be extensively used for various mechanism deceleration and stop/braking of various belt transport,port handling,hoisting, metallurgical, mining and building machinery.
3.Main Feature:
● The overall shape of the structure brake pads mounted on the card, the replacement is very convenient, fast, with semi-metallic (asbestos-free) of hard and semi-rigid, soft (including asbestos, asbestos-free), the braking of different materials pad for the user to select.
● 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;
● Braking by spring power;
● Lifting by thruster;
● Brake torque adjustable;
● Brake closes in case of power failure (Fail-Safe Principle);
4.Standards compliant
● The dimensions and braking torque parameters of YWZ8 series brakes comply with JB/ZQ4388-86 standard,technology requirements comply with JB/T6406-2006 standard;
● The dimensions and braking torque parameters of YWZ8-A series brakes comply with GB6333-86 standard,technology requirements comply with JB/T6406-2006 standard;
● They are equipped with Ed series thrusters which comply with DIN15430 standard.
5.Options and accessoires (selection):
● automatic wear adjustment (M);
● brake lining riveted and/or bonded
● different lining qualities and different coefficients of friction are available
● special design for horizontal or suspended mounting with support
● limit switches and monitoring devices for:
● brake indication (open/closed), residual stroke, brake lining wear etc.
● manual lifting
Type of operation:
