Description

YT1 Hydraulic Pusher For Tower Cranes & Industrial Drum Brakes

YT1 series electro hydraulic thruster is the most widely used domestic standard integrated hydraulic actuator, integrating AC motor, centrifugal oil pump and oil cylinder as one unit. Energized motor drives centrifugal pump to generate hydraulic pressure to extend push rod and release brake; power cut off, built-in load spring rapidly retracts push rod to trigger brake clamping. Divided into standard Z type, ZB lengthened stroke type and ZC cushioned retraction type, compatible with all mainstream YWZ series drum brakes, rail clamps, wheel windproof brakes. Ideal power drive for tower cranes, construction hoists, overhead cranes, mining conveyors and metallurgical transport equipment, featuring mature technology, affordable price and stable performance as mainstream upgrade replacement for old hydraulic thrusters.

Products Description

Core Competitive Advantages

Mature standard universal design, ultra cost-effective (Core Highlight)

Decades of mature mass production technology, standardized overall dimensions and mounting holes, perfectly matched all domestic YWZ drum brakes without bracket modification. Lower overall purchase price compared with imported ED series, standard universal spare parts greatly reduce long-term factory maintenance and inventory costs, the preferred economical brake drive for small and medium lifting machinery factories.

Integrated all-in-one compact structure, easy fast installation

Motor, pump and oil cylinder integrated casting molding, no external hydraulic pipelines, fewer connecting components, simplify on-site wiring and assembly steps. Vertical standard mounting design occupies small space, convenient for old equipment renovation and narrow undercarriage layout of tower cranes and small gantry cranes.

High-frequency continuous operation durable performance

Optimized centrifugal pump hydraulic circulation system, rated up to 720 working cycles per hour, support long-time frequent start-stop without thrust attenuation or motor overheating. B-class insulation motor stable operation under medium temperature workshop environment, suitable for 24h unmanned bulk material stockyard production linesZhongyuan ....

Multiple types to meet different working conditions

Standard YT1-Z: Ordinary general type for light-medium load workshop cranes;

YT1-ZB: Lengthened stroke type, match large torque heavy-duty drum brakes;

YT1-ZC: Built-in buffer spring cushioned retraction, slow push rod reset eliminate rigid impact, reduce brake lining wear and equipment vibration, ideal for port stackers and precision conveying equipment.

Spring passive fail-safe safety protection

Built-in high-strength load return spring, once power supply cuts off, circuit trips or hydraulic pressure disappears, push rod retracts instantly to lock brake drum, effectively prevent crane trolley sliding, hoist cargo falling and conveyor reverse sliding, meet industrial lifting safety mandatory standards. Optional upper/lower travel limit switches feed brake open/closed signal to PLC for full safety interlock controlZhongyuan ....

Low maintenance wear-resistant sealed construction

Push rod surface hard chrome plating + double composite sealing ring, effectively block oil leakage, extend seal service life;

Thickened cast iron cylinder housing with anti-rust coating, resist mine dust, cement ash and workshop corrosive gas without deformation and rust jamming;

Internal moving parts self-lubricated by working hydraulic oil, cancel frequent manual grease filling work;

Split structural design, quick disassembly for oil change and seal replacement without removing whole thruster from brake frame.

Diversified customized configurations

Complete model range covering YT1-18Z/2 ~ YT1-180Z/12 to match small to super large braking torque demands. Explosion-proof flameproof motor versions optional for chemical flammable workshops and underground coal mine hazardous equipment. Custom anti-corrosion coating, rainproof outer cover and special voltage (AC220V/415V) available for overseas export projects.

Main Application Scenarios

Tower cranes, construction passenger hoists, overhead/jib/gantry workshop cranes, port stacker-reclaimers, belt conveyors, metallurgical transfer trolleys, mining rail transport carts, bulk grain/ore yard machinery, matched with YWZ/YWR drum brakes, YFX/ZYTJ/YJGQ rail clamps, YLZ hydraulic wheel windproof brakes.
