ZYTJX‑120 Series Hydraulic Rail Clamp | Spring‑Applied Hydraulic Release Anti‑Wind Rail Gripper

ZYTJX‑120 Series Hydraulic Rail Clamp | Spring‑Applied Hydraulic Release Anti‑Wind Rail Gripper

ZYTJX‑120 Series Hydraulic Rail Clamp is a heavy‑duty fail‑safe anti‑wind safety device specially developed for rail‑mounted port cranes. It adopts spring‑clamping and hydraulic‑release working principle. When hydraulic pressure is lost, powerful compression springs drive the clamping jaws to firmly grip both sides of the rail to lock the crane position. When hydraulic pressure is supplied, hydraulic cylinder overcomes spring force to open the jaws and release the rail, allowing the crane to travel normally.

This rail clamp provides reliable storm‑proof protection for outdoor cranes, stopping equipment from sliding away under strong wind loads. Equipped with high‑wear‑resistant jaw pads, it maintains stable gripping force under long‑term cyclic operation. The heavy‑duty cast‑weld steel structure adapts to corrosive and heavy‑duty port working conditions. Jaw pads can be replaced without full disassembly of the unit, cutting down maintenance downtime.

ZYTJX‑120 Series Hydraulic Rail Clamp is a heavy‑duty fail‑safe anti‑wind safety device engineered for rail‑mounted port cranes. It operates on the principle of spring‑applied clamping and hydraulic release. When the hydraulic system loses pressure, high‑power compression springs drive the clamping jaws to firmly grip both sides of the rail, locking the crane in position and delivering stable anti‑creep holding force. When sufficient hydraulic pressure is provided, the hydraulic cylinder overcomes spring force to open the clamping jaws and release the rail, enabling the crane to complete normal travelling movements.

Thanks to its fail‑safe design, the rail clamp automatically engages clamping action upon hydraulic pressure failure. It delivers reliable storm‑proof protection for outdoor cranes and effectively avoids crane drifting and run‑away accidents caused by gusts and strong wind in port terminals and open‑air yards. Fitted with high‑strength wear‑resistant jaw pads, the clamp maintains consistent gripping force under heavy‑load and repeated cyclic operation.

The main frame adopts robust cast‑weld steel construction, featuring excellent impact resistance and corrosion resistance to cope with harsh coastal port working environments. The clamping gap can be easily adjusted on‑site to fit different rail specifications. With modular structural design, the jaw pads can be quickly replaced without complete disassembly of the whole unit, shortening maintenance cycles and reducing equipment downtime. All moving hinge parts are precision‑machined to ensure sensitive, stable and reliable mechanical response.

As an indispensable safety component for port lifting machinery, ZYTJX‑120 series hydraulic rail clamp is widely equipped on gantry cranes, container cranes and other large‑scale rail‑mounted lifting equipment for long‑term parking and wind‑proof anti‑creep protection.
