YT1‑18ZB/2 Electro‑hydraulic Thruster, Actuator For YWZ Series Crane Drum Brakes

YT1‑18ZB/2 Electro‑hydraulic Thruster, Actuator for YWZ Series Crane Drum Brakes

YT1‑18ZB/2 Series Electro‑hydraulic Thruster is a spring‑loaded hydraulic driving actuator widely used for industrial drum brakes. When energized, the internal motor drives hydraulic oil to push the piston rod outward to generate thrust, so as to drive the brake mechanism to release the brake. When power is cut off, the built‑in return spring pulls the piston rod back rapidly, helping the drum brake complete reliable braking.

This thruster is perfectly compatible with YWZ series drum brakes for lifting equipment. It features compact layout and small installation space. It delivers steady thrust under frequent cyclic operation with low running noise. Adopting high‑quality sealing components, it reduces oil leakage risk and suits indoor workshops as well as outdoor hoisting working sites.

Precision‑processed internal parts ensure stable long‑term operation. On‑site installation, commissioning and daily oil maintenance can be completed easily, lowering operating costs.

YT1‑18ZB/2 Series Electro‑hydraulic Thruster is a spring‑loaded hydraulic driving actuator mainly supporting YWZ series drum brakes for industrial hoisting machinery. When powered on, the built‑in motor drives the internal hydraulic assembly to push out the piston rod and generate rated thrust, driving the brake linkage mechanism to release the brake so that the host equipment can run normally. Upon power‑off, the built‑in return spring pulls the piston rod back quickly, enabling the drum brake to implement rapid and reliable braking action.

Designed with compact structure, this thruster occupies little installation space and can be directly assembled and matched with YWZ series drum brakes without extra modification. It outputs stable thrust, runs smoothly with low noise, and shows outstanding adaptability for frequent start‑stop cyclic working conditions. Adopting multi‑channel high‑quality sealing components, it effectively suppresses oil leakage, dust and moisture intrusion, and can work steadily in indoor workshops as well as outdoor hoisting sites.

All key internal components are precisely machined and strictly inspected, achieving low failure rate and long service life. The whole unit is convenient for field installation and commissioning. Routine inspection and hydraulic oil replacement can be completed efficiently, which greatly reduces daily maintenance workload and operating cost.

As an indispensable core driving part of braking systems, YT1‑18ZB/2 series electro‑hydraulic thruster is widely applied to overhead cranes, gantry cranes, electric hoists and belt conveyors, cooperating with drum brakes to realize stable deceleration and safe parking braking for lifting and conveying equipment.
