Product Introduction
The SQZ8000 is a flagship model within the heavy-duty folding boom crane series. This series centers on formidable lifting capacity, featuring key characteristics such as a low-profile chassis, exceptional performance in confined height spaces, robust load-bearing telescoping capability, precise micro-movement coordination, and comprehensive lifting capabilities. With a complete and comprehensive range of lifting capacities, with a comprehensive and complete model range. It is the star product for large-tonnage precision lifting operations in confined height spaces such as factories and tunnels.
Product Advantage
The vehicle features lightweight design with low curb weight, ensuring compliance with regulatory limits;
Its compact body and small turning radius facilitate maneuverability in confined spaces;
Low profile allows unrestricted access to various workshops and factory buildings. Equipped with a four-section telescopic boom, all sections feature dual-push technology for enhanced lifting capacity and load-bearing extension capability. Sequential extension cylinders with buffering ensure reliable operation, delivering smooth and stable extension for precise and efficient work;
Quick-release counterweight system: Removal reduces swing radius; addition enhances overall stability and lifting performance;
Maximum 35-ton counterweight moves with the turntable, plus an additional 5-ton fixed counterweight on the chassis. Self-loading/unloading is simple and efficient;
Three high-torque gearboxes deliver powerful slewing power and excellent braking performance, ensuring smoother rotation and safer operation;
An exceptionally robust integrated square box frame + 6-leg structure provides the crane with formidable all-around working capabilities.

Product Uses
1. Bridge and Large-Scale Infrastructure Construction
This crane is ideally suited for tasks such as installing bridge superstructures and lifting large precast components. Its low-profile design enables safe and efficient operation in height-restricted spaces beneath bridges, such as those with overhead power lines, effectively overcoming the limitations traditional equipment faces in complex environments.
2. Heavy Industrial Plant and Equipment Installation
Within various workshop facilities, this equipment facilitates the installation, positioning, and maintenance of heavy machinery. Its low overall height allows unrestricted access to diverse workshop environments. The powerful load-bearing telescoping capability and rapidly deployable counterweight system (maximum 35-ton slewing counterweight + 5-ton chassis counterweight) meet the demands for high-tonnage precision lifting within industrial plants.
3. Wind Power and Energy Construction Projects
This crane's formidable lifting capacity enables it to handle heavy-duty hoisting tasks in the energy sector, such as installing wind turbine components. Its lateral lifting capability (120 tons) and comprehensive safety systems (including overload protection and oil lock functions) ensure secure execution of these critical operations.
4. Heavy Logistics and Oversized Cargo Handling
At ports, terminals, or large logistics hubs, it facilitates the loading, unloading, and transfer of oversized cargo and equipment. Its fully remote-controlled operation system enhances operational flexibility. The robust integrated box-type frame with six outriggers delivers exceptional all-around performance and stability, meeting the demands of specialized heavy-lift companies for complex maneuvers and harsh environments.
Product Operate Guide
Operating the SQZ8000 heavy-duty crane requires a valid Special Equipment Operator Certificate. Before operation, thoroughly inspect the equipment condition and confirm all components are in good working order. Fully extend the 6-leg system on solid, level ground to achieve stable support. Strictly adhere to the load chart and moment limiter data; overloading is strictly prohibited. Maintain smooth and precise movements during operation while monitoring the surrounding environment. Conduct regular inspections of wire ropes, hooks, and safety devices, maintaining detailed maintenance records. After completing operations, retract the boom to a safe position and disconnect the power supply.
FAQ
1. WHAT SHOULD I DO IF THE EQUIPMENT SUDDENLY LOSES POWER?
Immediately stop the machine smoothly. Inspect the fuel supply system, hydraulic system, and electrical system. Restart only after troubleshooting the issue.
2. HOW DO I PROPERLY OPERATE THE HYDRAULIC SYSTEM?
Answer: Check the hydraulic oil level before operation. Avoid prolonged operation at extreme positions during use. Monitor changes in hydraulic oil temperature.
3. WHAT TASKS ARE REQUIRED FOR ROUTINE MAINTENANCE?
Includes checking engine oil, hydraulic fluid, and coolant levels; cleaning the air filter; inspecting tire or track condition; and tightening all connecting components.
4. HOW SHOULD EQUIPMENT BE PROPERLY STORED?
Clean the equipment, fill fuel tanks, drain water from reservoirs, apply rust prevention to exposed metal parts, and start the engine monthly for operation.
5. HOW SHOULD THE BATTERY BE MAINTAINED?
Keep terminals clean. Regularly check electrolyte level and specific gravity. Disconnect the negative terminal during extended storage. Charge monthly.
6. HOW TO RESOLVE INSUFFICIENT HYDRAULIC SYSTEM PRESSURE?
Check hydraulic fluid level and quality. Inspect the hydraulic pump, control valves, and cylinders for internal leaks or damage.
