Brake Air Chamber is the core component of loader brake system. It uses compressed air to push internal diaphragm to amplify braking force and drive brake master cylinder to realize vehicle braking, ensuring sensitive and reliable braking during loader driving and operation. Adopts aluminum- alloy housing and stamped steel structure with good sealing and high pressure resistance. Compatible with mainstream 5- ton wheel loaders, widely used for equipment repair and used- loader refurbishment export for heavy- duty mine and construction- site working conditions.

Air Conditioning Compressor is the core part of loader cab air- conditioning system. It compresses refrigerant to realize coolant circulation and provides cooling for operator cab, improving working condition under high- temperature environment. Adopt aluminum- alloy housing with precision internal piston and valve plate assembly, driven by electromagnetic clutch. Compatible with mainstream 5- ton wheel loaders, widely used for equipment repair and used- loader refurbishment export for high- temperature mine and construction- site working conditions.

This loader air brake valve adopts integrated die-cast aluminum alloy valve body with mechanical foot drive structure, the core control component of vehicle air brake system. Step on foot pedal to drive internal push rod and valve spool to open air inlet channel synchronously, high-pressure air from air tank deliver to front & rear brake chambers for vehicle deceleration and parking. Equipped with multi-layer oil-resistant rubber seals and return spring inside, featuring follow-up braking, rapid pressure relief and double seal anti-leakage function. Flange mounting bracket and standard air port threads fully fit original brake pipelines of 5-ton loaders, standard replacement spare part for used loader air circuit overhaul. It can completely fix faults such as slow brake response, air leakage, weak braking and slow return

This dual-circuit pneumatic foot brake valve is specially designed for 5-ton wheel loaders, the core control component of vehicle air brake system. It adopts integrated cast aluminum valve body + anti-slip corrugated stepping pedal, built-in two independent air circuits, equipped with standard dust-proof plastic air port caps. When stepping on the pedal, two independent high-pressure air channels output air simultaneously to control front and rear axle brake chambers separately. Dual-circuit safety design ensures partial braking capacity even if one circuit leaks. Oil & high-pressure resistant rubber seals inside valve body, adjustable pedal stroke, direct mounting matching original cab floor holes. Compatible with all kinds of used 5-ton loaders of Liugong/XCMG/Lingong for refurbishment maintenance and complete machine export matching.

This unloader valve is dedicated air pressure control valve for loader air compressor, integral cast aluminum valve body, built-in pressure regulating spring, sealed piston and multi-channel air ports, integrating pressure regulation, unloading and exhaust functions. High-pressure air from air compressor flow into valve body. When air tank pressure reaches set value, piston opens automatically for unloading to make compressor run under no load; when pressure below threshold, unloading channel closes and restart air charging to stabilize vehicle air circuit pressure, guarantee stable air supply for brake, horn and air shift valve. Standard multi-channel air ports and thread adjusting screw universally fit air compressor of 5-ton loaders, standard replacement spare part for used loader air circuit overhaul. It can completely fix faults such as pipe burst caused by excessive pressure, weak brake due to insufficient air pressure and long-term full-load compressor wear, widely supplied for domestic repair shops and overseas mining complete machine refurbishment & export. Supported by Qinyang Hengsheng 24-hour multilingual cross-border after-sales technical service.
