Products Details
Hydraulic Outriggers + Side Guards
Features
Outriggers: Cylindrical vertical hydraulic cylinders featuring large, detachable load-bearing pads at the base and yellow-and-black warning markings.
Guards: Welded rectangular steel tube frames with an open-mesh design, positioned behind the outriggers to protect hydraulic lines and cables.
Advantages
Operational Safety: Large-diameter outriggers and wide pads effectively resist tipping and adapt to soft ground, ensuring stability for 70-ton class lifting operations.
Reliable Protection: Steel guards prevent flying debris from damaging high-pressure hydraulic hoses, while the open-mesh structure allows easy access for routine maintenance.
Slewing Bearing Assembly
Features
Large-scale annular raceway structure (internal or external gear type) with densely arranged gear teeth on the ring surface.
Rigidly connected between the yellow superstructure (turntable) and the gray chassis via high-strength bolts and the gear ring.
Equipped with a central rotary joint to facilitate the passage of hydraulic fluid and electrical signals between the upper and lower sections.
Advantages
High Load Capacity: Serving as the vehicle's core load-bearing pivot, it withstands the immense overturning moments and axial loads associated with 70-ton class lifting.
Smooth, Precise Slewing: High-precision gear ring combined with hydraulic drive ensures smooth starting and stopping and excellent inching control, guaranteeing accurate positioning during high-altitude lifts.
Impact Resistance and Durability: Heavy-duty raceway and embedded roller design withstand frequent heavy-load rotation in harsh operating conditions, ensuring a long service life.
Superstructure (Turntable) and Main Boom Assembly
Features
Main Boom: Welded high-strength steel structure with a large-section U-shaped or hexagonal profile; features "QY70K-II" model branding on the side and a visible truss-style jib at the top.
Engine Enclosure: Yellow metal housing featuring dense mesh ventilation grilles on the sides and a cylindrical black air intake/exhaust unit at the rear.
Advantages
High Load Capacity: High-strength steel boom structure combined with high-thrust luffing cylinders meets the length and strength requirements for 70-ton class heavy-duty lifting.
Excellent Heat Dissipation: Large-area mesh enclosure design effectively dissipates heat from the engine and hydraulic system, preventing overheating during continuous, high-load operations. Compact Layout: The power system, hydraulics, and main boom are all housed on the upper superstructure, resulting in a compact overall structure that facilitates easy relocation between job sites.
Slew Reducer + Hydraulic Motor
Features
Hydraulic Motor: Features a yellow cylindrical housing with inlet and outlet ports at the top, connected to hydraulic lines and fittings encased in black protective sleeves.
Reducer: Contains an internal planetary gear reduction mechanism; the output shaft features a pinion gear that meshes tightly with the large black external gear ring (slewing bearing) below.
The entire assembly is welded or flange-mounted to the underside of the upper turntable, ensuring a compact design.
Advantages
High Driving Torque: The planetary reduction mechanism converts high-speed/low-torque input into low-speed/high-torque output, effortlessly rotating the upper structure and its load - weighing tens of tons.
Reliable Braking: An integrated hydraulic brake valve allows for instant locking of the slewing angle, preventing unwanted rotation caused by slopes or wind and ensuring precise positioning.
Long Service Life: The enclosed gearbox design effectively keeps out dust and contaminants, significantly extending the unit's lifespan in harsh outdoor operating environments.
