YJGQ Hydraulic Rail Clamp – Compact Split Design, Floating Jaw Spring Fail-Safe Wind Lock

 

 

Core Competitive Advantages

Compact split structure, fit narrow installation space (Core Highlight)

Separate hydraulic station and rail clamp main body, small-size clamp body occupies minimal undercarriage space, perfect for old equipment renovation and small cranes with limited reserved mounting area. Flexible pipeline layout, customers can place hydraulic station at convenient position without space restriction of integrated all-in-one clamps. Light overall weight reduces extra load on crane walking mechanism.

Spring passive fail-safe locking with manual pump backup

Static state spring keeps jaws tightly clamping rails automatically, no power or hydraulic oil support required, effectively prevent equipment sliding under strong wind during power outages. Reserved external manual pump interface, operators can connect portable hand pump to manually open jaws for inspection and maintenance, solving the stuck maintenance problem of ordinary rail clamps without manual release function.

Floating jaw self-compensate track installation tolerance

Horizontal floating range ±20mm, vertical floating buffer eliminates rigid extrusion between jaws and rails caused by track uneven settlement, installation offset and trolley running swing. Avoid unilateral rail scratching and abnormal abrasion, greatly extend service life of steel rails and alloy friction jaws, cut track maintenance costs for yards.

Full safety interlock with travel limit switch

Open/closed position feedback switch hard-linked to crane travel control circuit. The walking system cannot be activated when clamp jaws are not fully released, completely eliminate major collision accidents caused by traveling with locked rail clamp, meet safety operation standards of unmanned bulk material yards.

Ultra-low maintenance modular design

All rotating hinge parts adopt self-lubricating maintenance-free bearings, no regular grease filling needed for long-term continuous operation;

Snap-on alloy wear-resistant jaws, quick replacement without complete disassembly of clamp frame, save maintenance time by more than 60%;

IP65 sealed shell with heavy anti-corrosion salt-fog coating, resist mine dust, cement ash and coastal humid salt mist without rust jamming;

Wide rail compatibility, supports P38/P43/P50/P60 light rails and QU70/QU80 heavy crane rails, one model adapts multiple track specifications.

Diversified customized configurations

Complete YJGQ model range with different clamping force for light to medium load equipment. Explosion-proof hydraulic components optional for flammable chemical workshops and underground coal mine light rail machinery. Custom left/right symmetric mounting brackets, external rain shield and heavy-duty anti-rust coating available. Can be used alone or matched with YLZ hydraulic wheel brake to build dual anti-typhoon safety protection system.
