Core Competitive Advantages
German standard non-immersed F-class motor + aluminum alloy body (Core Highlight)
Adopt non-immersed motor structure, stator winding completely separated from hydraulic oil, eliminate oil aging leading to coil burnout fault, F-class insulation withstand high temperature continuous operation. Cast aluminum alloy shell is lighter than traditional cast iron, excellent heat dissipation and salt fog anti-corrosion performance, ideal for coastal port and high-temperature metallurgical harsh environments.
Built-in balance air chamber, 0–180° arbitrary multi-angle installation
Unique balance air chamber design on cylinder body, no matter vertical, horizontal or inclined mounting angle, internal oil pressure remains balanced without air lock failure, solve installation space limitation pain point of old YT1 thrusters, fit narrow crane undercarriage layout and complex mechanical structure transformationHuawu.
Double-layer full sealing structure, long-term zero oil leakage
Push rod surface adopts special hardening anti-wear treatment, matched double composite sealing ring; IP65 fully sealed junction box with cable waterproof gland, prevent dust, rain, salt mist invading internal components, no frequent oil refilling and seal replacement maintenance work.
Smooth low-noise high-frequency continuous operation
Hydraulic centrifugal pump stable pressure output, no rigid impact vibration during push rod extension & retraction, low running noise. Support long-time frequent start-stop cycle, no overheating attenuation of thrust, adapt 24h unmanned port yard and bulk material stockyard working conditions.
Optional limit switch safety interlock function
Can equip upper limit switch (brake open signal) + lower limit switch (brake closed signal), real-time transmit working status to PLC control cabinet, realize full safety interlock with crane travel system, avoid equipment traveling with brake clamped and cause collision accidents.
Complete specifications & wide matching range
Full model series ED23/5, ED30/5, ED50/6, ED80/6, ED121/6, ED301/6, ED450/8 cover small to super large thrust stroke demands. Directly match all domestic mainstream drum brakes, rail clamps, wheel windproof brakes without bracket modification. Explosion-proof flameproof versions customized for chemical and underground coal mine hazardous zones.
