Product Introduction
This crane prioritizes safety and efficiency, featuring a combined proportional hydraulic system that enables full composite crane operations while delivering exceptional micro-movement control and faster working speeds. Its torque limiting device and over-hoist protection effectively enhance operational safety, preventing overloads and misoperations. The dual-rotation mechanism ensures smoother operation and superior self-locking performance. Additionally, the automatic hook retraction function reduces setup time and enhances crane safety. Standard features like the elevated operator seat, dual-side access ladders, and hydraulic oil cooler further demonstrate its user-centric design.
Product Advantage
* Single cylinder synchronization guy cable technology makes work efficiency higher than before.

Product Uses
1. Large-scale Infrastructure Construction
Ideal for hoisting operations in major projects like high-speed railways and bridges, enabling efficient ballastless track laying, guardrail installation, and utility pole support. Its maximum lifting moment of 520 kN·m and excellent stability meet heavy-duty material handling demands on complex construction sites.
2. Heavy Logistics Transportation and Handling
In ports, large warehouses, and factories, it efficiently handles loading/unloading and transferring heavy machinery and bulk materials. Its 360° full rotation capability enables flexible operation in confined spaces, boosting logistics efficiency.
3. Mining and Quarry Operations
It handles the lifting of large ore blocks, stone materials, and equipment components in mining and quarry settings. Its robust structural design and 20-ton maximum lifting capacity withstand harsh conditions, though ground load-bearing capacity and equipment maintenance require attention.
4. Power and Energy Equipment Installation
In power construction, oil extraction, and related fields, it assists in installing large transformers, cable reels, and small petroleum equipment. Its precise control system and smooth flow from the dual-pump system suit demanding lifting operations.
5. Industrial Equipment Installation and Maintenance
In large factory workshops, it handles the installation, positioning, and maintenance of heavy production equipment. Its maximum boom length of 23.7 meters and lifting height of 25.5 meters cover most internal workshop height requirements.
Product Operate Guide
SQS500-5 operation must be strictly standardized. Before operation, ensure outriggers are fully extended and supported on solid, level ground. Continuously monitor the load moment indicator (LMI) during operation; overloading is strictly prohibited. Control boom movements smoothly via the control console, paying attention to the steady flow provided by its dual-pump hydraulic system (recommended 80+50 L/min). A dedicated signal person must direct lifting operations to ensure cargo is securely lashed and personnel are kept clear. After operation, fully retract and secure the boom, and perform regular maintenance. Operators must be certified.
FAQ
1. HOW TO TROUBLESHOOT A MALFUNCTIONING LIGHTING SYSTEM?
Check fuses, bulbs, switches, and wiring connections. Use a multimeter to measure voltage and continuity.
2. WHAT PRECAUTIONS SHOULD BE TAKEN WHEN SERVICING THE BRAKING SYSTEM?
Use specialized tools, disassemble in sequence, replace worn components, adjust clearances after installation, and conduct a test.
3. HOW TO SAFELY OPERATE ON INCLINES AND DECLINES?
Maintain low speed, avoid shifting gears or turning, and use auxiliary braking devices when necessary.
4. WHAT PRECAUTIONS SHOULD BE TAKEN DURING RAINY WEATHER OPERATIONS?
