1.Introduction
YW-E Series Electro-hydraulic Drum Brakes(with type ED electrohydraulic thruster)DIN15435

● Original:He Nan, China
● Certification: ISO9001, ISO14001, OHSAS18001, TX, EX, MA etc
● Packing: export standard
● Max. Drum Diameter(mm) :400
● Max. Brake Torque (Nm) :2500
● Operating Condition" Ambient temperature: -20°C~+50°C ;
● Relative humidity:≤90%;
● Power:AC 3 phases 50(60)Hz
● Voltages: 380~400V 50Hz  440~460V 60Hz
● Operating duty: intermittent (S3-60%.1200times per hour)and continuous (S1).
● Special requirements can be discussed in order.


2.Application:
●YW-E Electro-hydraulic drum brakes are mainly used for large/middle outdoor crane with excellent deceleration braking and storm braking performance. This brake can also used on large and middle special cranes to assure stable deceleration braking and maintenance braking. It is also good choice to use on belt transport vehicle.
●YW-E series brake is two-step braking device. In the first step, a minor torque is exerted to make stable deceleration braking. The second step will start when the device stopped; a bigger torque is exerted to realize reliable maintenance or storm braking. The second step can be adjusted by damping single way throttle in cylinder circuit(with 1-15 seconds)


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 YW-E series brakes comply with DIN15435 standard,technology requirements comply with JB/6406-2006 standard;
● They are equipped with Ed series thrusters which comply with DIN15430 standard.


5.Options and accessoires (selection):
● Brakes are made acc. to DIN 15 435, therefore interchangeability is guaranteed
● Enclosed spring tube protects spring from damage and contamination
● Brake torque adjustable, brake torque scale in Nm-segments for coefficient of friction µ = 0,4
● driven to drive with a decline in the delay valve, brake delay closure;
● 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(K1 or K2);
● brake indication (open/closed), residual stroke, brake lining wear etc (K3);
● manual lifting (S1 or S2).
