ZYTJX-120 Series Hydraulic Rail Clamp

ZYTJX-120 series hydraulic rail clamps are normally‑closed, hydraulically released safety devices specially designed for windproofing, anti‑sliding and emergency securing of large traveling cranes, gantry cranes, shipyard cranes, port machinery and other outdoor rail‑mounted equipment.

Basic Information

Model: ZYTJX‑120 series

Type: Hydraulic rail clamp

Operation: Spring applied, hydraulically released (normally closed)

Function: Rail clamping, windproof braking, anti‑sliding, parking

Suitable rail type: Matched for rails according to 120‑class clamping capacity

Working Principle

Clamping / braking state (power/hydraulic off):Heavy‑duty built‑in springs drive the clamping jaws to firmly grip the steel rail, providing strong holding force.

Release state (hydraulic on):The hydraulic cylinder retracts the jaws, releasing the rail to allow the machine to travel.

Fail‑safe:Automatically clamps the rail during power loss or hydraulic failure, ensuring safety under strong wind or typhoon conditions.

Key Features

Normally‑closed fail‑safe design for high reliability

Hydraulic drive with stable action and low noise

High clamping force, excellent windproof and anti‑sliding performance

Compact structure, easy installation and adjustment

Wear‑resistant jaw pads, long service life

Suitable for outdoor heavy crane equipment and harsh environments

Typical Applications

Gantry cranes & shipyard gantry cranes

Port container cranes

Bridge cranes & rail‑mounted traveling machinery

Large outdoor equipment requiring rail clamping and wind protection

Short version 

ZYTJX‑120 series hydraulic rail clamps are normally‑closed, spring‑applied, hydraulically released rail‑clamping devices used for windproofing, anti‑sliding and safe parking of large rail‑mounted cranes and outdoor heavy machinery.
