Product Description
The QY80K5C is a heavy‑duty 80‑ton truck‑mounted hydraulic crane designed for medium‑and‑large‑scale lifting jobs and heavy‑duty rental fleets worldwide. It features a 5‑section high‑strength U‑shaped telescopic main boom reaching 50.5 m, matched with 16 m auxiliary jib to achieve maximum lifting height of 66.6 m and 3557 kN·m rated basic lifting moment.
Equipped with advanced confluence hydraulic system and inertia‑moment buffer technology, the machine delivers smooth, low‑impact slewing and precise compound lifting movements. Powered by Weichai high‑torque engine of 294 kW, it supports up to 80 km/h highway travel for fast site‑to‑site transfer with optimized fuel‑saving performance. Large‑span dual‑level outriggers greatly improve stability under heavy‑load and long‑boom working conditions. High‑end balance valves, double‑caliper disc brake and heavy‑duty tires enhance overall safety and durability. This 80‑ton mobile crane is a reliable workhorse for urban viaduct construction, steel‑structure installation, bridge engineering, plant erection and large‑volume rental business.
Product Advantages
Strong Lifting Capacity 50.5 m five‑section U‑shaped high‑strength main boom plus 16 m auxiliary jib, max lifting height 66.6 m, rated lifting moment 3557 kN·m. It can carry 24.6 t counterweight during transit, covering 92% of common working conditions. 20 mm large‑diameter steel wire rope improves lifting performance.
Stable & Precise Hydraulic Control Adopts inertia‑moment buffer matching technology to reduce impact during slewing stop. Advanced confluence hydraulic system realizes smooth single and compound actions. Premium luffing & lifting balance valves ensure stable load holding without slipping under heavy load.
Power‑saving Powertrain & Fast Mobility 294 kW Weichai high‑torque diesel engine, max travel speed 80 km/h, max gradeability 47% for complex road conditions. Optimized hydraulic circuit reduces energy loss, lowers fuel consumption for long‑hour continuous site work. Large‑capacity fuel tank extends working cycle.
High‑safety Chassis & Robust Structure Dual‑level large‑span outriggers improve anti‑overturn performance for long‑boom heavy‑load operation徐工集团. Industry‑leading double‑caliper disc brake upgrades driving safety. 20PR heavy‑duty tires increase bearing capacity by 40%. Reinforced boom structure adapts to harsh outdoor construction environments.
Human‑oriented Cab & Easy Maintenance Dual‑cabin design with comfortable driving & operating space, clear instrument display and optimized control layout. Key components adopt globally‑accessible spare‑parts for convenient after‑sales maintenance.

Product Application
‑ Urban viaduct & high‑rise building construction: steel‑structure hoisting, component installation ‑ Bridge engineering: bridge segment lifting, highway maintenance and reconstruction ‑ Industrial project: factory equipment erection, petro‑chemical plant construction ‑ Municipal engineering: large billboard installation, urban renovation work ‑ Rental fleet: heavy‑duty short‑term & long‑term site leasing business ‑ Infrastructure projects: wind‑power auxiliary hoisting, large‑scale logistics handling
Operation Guide
Pre‑operation Inspection Check engine oil, hydraulic oil level, steel wire rope wear condition, outriggers, safety limit alarm devices and braking system before startup. Confirm ground bearing capacity for outrigger supporting area.
Site Setup Fully extend four outriggers and level the whole machine strictly. Never operate with partially stretched outriggers. Keep safe clearance from overhead power lines.
Lifting Operation Read load‑chart strictly before hoisting. Strictly avoid overload lifting. Operate joystick gently; prevent sharp acceleration or sudden stop during compound movements.
Transfer Travel Condition Fully retract boom and jib, stow hook block before highway driving. Comply with local road weight and dimension regulations.
Daily Maintenance Lubricate key points, check hydraulic pipe joints and bolt tightness after daily shift. Replace filters and hydraulic oil following official service manual schedule.
Warning: Only certified, well‑trained crane operators are permitted to operate this equipment.
