DYTP1750‑S/90 is a heavy‑duty parallel‑type electro‑hydraulic pusher (integrated motor, pump, cylinder), widely used for linear actuation in industrial brakes, valves, conveyors, and metallurgical equipment.
DYTP: Series code (D=electric, Y=hydraulic, T=pusher, P=parallel)
1750: Rated thrust 1750 kgf ≈ 17,150 N
S: Structural code (standard, horizontal/vertical mounting)
90: Rated stroke 90 mm
2. Working Principle
Power ON (Extend): Motor drives hydraulic pump, building pressure to extend the rod with 17,150 N thrust.
Power OFF (Retract): Motor stops, pressure releases, and the load/spring retracts the rod.
Self‑locking: Built‑in hydraulic lock holds position without power (fail‑safe).

4. Core Features
High thrust & large tension: 17,150 N / 11,270 N for heavy loads.
Parallel compact design: Saves installation space vs. vertical pushers.
Self‑locking & overload protection: Hydraulic lock + overload relief valve for safety.
Adjustable speed & force: Infinitely variable speed/force via hydraulic control.
Durable & sealed: IP54 + Class F insulation for dust/moisture resistance.
5. Typical Applications
Heavy‑duty brakes: YWZ, YWZB, ZWZB series drum brakes (crane/hoist).
Conveyors & feeders: Material flow control, tensioning, and emergency stop.
Metallurgy & mining: Sintering machines, crushers, and heavy rollers.
Valve actuation: Gate valves, dampers, and sluice gates in power/chemical plants.
Port machinery: Container cranes, ship unloaders, and loading arms.
