Application: The YWZ3-E series electric hydraulic drum brake is widely used in the operation mechanism of various large and medium-sized outdoor cranes, with excellent deceleration braking performance and ideal windproof braking effect; This product can also be used for the operation mechanism of large and small cranes, achieving smooth deceleration braking and excellent maintenance braking; This product also has ideal braking performance for working brakes used in belt transportation
The YWZ3-E series electric hydraulic drum brake is a two-step braking device. Firstly, apply a small (adjustable within the specified range as needed) braking torque and perform a smoother deceleration braking. After the mechanism stops moving, the excellent step braking begins and an additional braking time is added. The adjustment can be made through the one-way speed control valve in the damping oil cylinder circuit according to actual needs (the adjustment range is 1-15 seconds)
Compliance with standards:
The connection dimensions and braking torque parameters of the YWZ3-E series electric hydraulic drum brake comply with JB/T6406-2006, JB/ZQ4388-86 (with A series), and DIN15435 standards.
. Equipped with Ed series thrusters that comply with DIN15430 standard
Main features:
▲ Interlocking distance equalization device and tile automatic follow-up device, which can always maintain equal distance between the two tile blocks without adjustment, completely avoiding the phenomenon of one side brake pad floating against the brake wheel due to uneven distance.
The main swing hinge points are equipped with self-lubricating bearings, which have good transmission efficiency, long service life, and no need for lubrication during use▲ The brake spring is arranged inside the square tube and equipped with a ruler, allowing users to easily read the braking force torque value, eliminating the hassle of measurement and calculation▲ The brake pad is a card mounted integral formed structure, which is easy and fast to replace. There are different materials of brake pads available for users to choose from, including semi metal (asbestos free) hard and semi hard, soft (asbestos free) brake pads▲ Equipped with Ed series electric hydraulic thrusters, it has sensitive movements and long service life▲ Normally closed design, (power off) spring brake, (powered on) thruster release
