Product Introduction
This crane prioritizes safety and efficiency, featuring a dual-pump combined hydraulic system that enables composite crane operations and enhances hoisting efficiency. Its operational efficiency surpasses industry standards by 10% to 25%. Incorporating constant torque limiting technology, it delivers high precision, reliability, and safety. Additionally, its automatic hook retraction technology reduces preparation time by over 5% while effectively preventing hook sway, enhancing overall crane safety. The domestically pioneering throttle linkage technology enables automatic acceleration and deceleration via dual main valve handles, achieving 5%–10% energy savings. Optional configurations include four-way control and elevated seats, enhancing operational convenience and comfort.
Product Advantage
Single cylinder synchronization guy cable technology makes work efficiency higher than before. Advanced development means make sure that the design is very reliable. The more symmetrical center design of pentagon or hexagon boom make it has bigger anti-bending capacity. Compact hinge point design takes up smaller space. The work is more safety after fitted with alarm device. The integer lifting winch improved the work efficiency greatly and prolonged work life of hydraulic system. Float three -point bridge structure design can lower the accessional stress on the chassis when traveling. It has been fitted own powerful slewing of working in diversifying conditions. Anti-slewing impulse equipment makes vehicle running safety.

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 300 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 substantial 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 optional dual-winch auxiliary hook/boom technology suit demanding lifting operations.
5. Emergency Response and Special Operations
Suitable for disaster relief, accident site rescue, and other urgent tasks, it rapidly clears obstacles and repairs equipment. Its mobility and rapid deployment capabilities ensure efficient rescue operations.
Product Operate Guide
SQS300-4 operation must strictly adhere to specifications. Before commencing work, ensure outriggers are fully extended and supported on solid, level ground. Monitor the load moment indicator (LMI) throughout operation; overloading is strictly prohibited. Control boom movements smoothly via the control console, leveraging the performance advantages of its industry-first arc boom technology. During lifting operations, a dedicated signal person must direct 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 EXTEND EQUIPMENT LIFESPAN?
Strictly follow the maintenance manual for upkeep, adhere to standard operating procedures, avoid overloading, and promptly address minor malfunctions.
2. WHAT SHOULD BE NOTED WHEN ADJUSTING TRACKS?
Adjust on level ground, maintain proper tension, and regularly inspect track pins and bushings for wear.
3. HOW TO RESOLVE BLACK SMOKE FROM THE ENGINE?
Check for clogged air filters, verify proper fuel injection system function, and ensure the turbocharger operates effectively.
4. HOW SHOULD ELECTRICAL SHORT CIRCUITS BE HANDLED?
Disconnect the power supply. Use a multimeter to locate the short circuit point. Repair damaged insulation and replace faulty wiring harnesses.
5. HOW CAN EQUIPMENT DATA BE EXPORTED FOR ANALYSIS?
