ZYTJ Hydraulic Rail Clamp – Spring Fail-Safe Lock, Emergency Manual Pump For Power Failure

 

 

Core Competitive Advantages

Spring fail-safe passive clamping + emergency manual pump backup (Core Highlight)

Normally closed spring structure ensures automatic rail locking without power/hydraulic support, completely avoid equipment sliding under typhoon during power outage. Independent hand-operated manual pump reserved on hydraulic station; operators can manually release clamp jaws for equipment maintenance when power is fully cut off, solve maintenance deadlock pain point of ordinary rail clamps.

Floating clamp body adapt rail installation tolerance

Horizontal floating range ±20mm, vertical floating ±10mm, automatically compensate track installation deviation, uneven settlement and trolley running offset. Prevent single-side jaw forced friction rail surface, reduce rail scratch and wear, extend service life of both steel rails and alloy clamp jaws.

Travel limit switch full safety interlock

Built-in open/closed position feedback limit switch, hard-wire interlock with crane traveling control cabinet. Crane cannot start traveling when clamp jaws are not fully released, eliminate major collision safety accident caused by running with locked rail clamp, realize full unmanned intelligent safety protection for port yards.

Dual-scenario all-condition windproof protection

Realize two-layer anti-drift safety: minor crosswind anti-slip protection during crane loading/unloading operation; full storm locking when long-term unattended shutdown. Can be combined with YLZ hydraulic wheel brake to form double anti-typhoon safety system for large container terminals, cope with level 10–12 coastal typhoon environment.

Ultra-low maintenance modular design

All swing hinge pivot points adopt maintenance-free self-lubricating bearings, cancel periodic grease filling work;

Plug-in alloy wear-resistant clamp jaws, quick replacement without disassembling whole clamp main body, save over 60% maintenance downtime;

IP65 fully sealed hydraulic station and clamp housing, heavy-duty salt-fog anti-corrosion coating, adapt coastal high humidity, mine dust and cement plant harsh environment without rust jamming;

Complete rail adaptation range, compatible with P38/P43/P50/P60 light rails and QU70/QU80/QU100/QU120 heavy crane rails, one model fits multiple rail specifications.

Diversified customized configurations

Complete ZYTJ model series with different clamping force from light to heavy tonnage. Explosion-proof hydraulic station versions optional for chemical flammable workshops and underground coal mine hazardous rail equipment. Custom left/right symmetric mounting brackets, external rain shield and heavy anti-corrosion paint available, flange direct mounting simplify crane undercarriage installation layout.

Main Application Scenarios

Port rail-mounted container gantry cranes (RMG), outdoor portal gantry cranes, container stacker-reclaimers, ship unloaders, belt conveyor tripper cars, metallurgical rail transfer trolleys, mining bucket wheel stacker-reclaimers, bulk grain/ore yard outdoor rail running machinery requiring anti-typhoon windproof locking.
