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 in 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 dual-rotation mechanism operates smoothly, enabling agile maneuvering in confined spaces to boost logistics efficiency.
3. Mining and Quarry Operations
Used for lifting large ore blocks, stone materials, and equipment components in mines and quarries. Its robust structural design and 16-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 and oil extraction sectors, it assists in installing large transformers, cable reels, and small petroleum equipment. Its proportional hydraulic system delivers excellent micro-movement control and fully composite actions, making it suitable for demanding precision lifting tasks.
5. Industrial Equipment Installation and Maintenance
Within large factory workshops, it facilitates the installation, positioning, and maintenance of heavy production machinery. Its multi-cylinder sequential telescoping mechanism delivers powerful load-bearing extension capabilities, meeting diverse heavy equipment handling needs within industrial facilities.
Product Operate Guide
SQS500B operation must strictly adhere to regulations. Before commencing work, ensure all 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, utilizing the precise micro-movement capability provided by its proportional hydraulic system. A designated signal person must direct lifting operations to ensure cargo is securely lashed and kept clear of personnel. After operation, fully retract and secure the boom. Perform regular maintenance. Operators must be certified.
FAQ
1. HOW TO ENSURE SAFETY WHEN WORKING NEAR HIGH-VOLTAGE LINES?
Maintain a safe distance, set up warning signs, assign a dedicated supervisor when necessary, and use insulated protective equipment.
2. HOW TO PREVENT ROLLOVER ACCIDENTS?
Understand the equipment's stability range, avoid lateral operations on slopes, monitor the load's center of gravity, and use safety devices.
3. How to extend equipment lifespan?
Maintain strictly according to the maintenance manual, operate properly, avoid overloading, and address minor faults promptly.
4. WHAT IS THE REPLACEMENT CYCLE FOR FILTERS?
Air filter: Inspect every 500 hours, replace every 1000 hours.
Fuel filter: Replace every 500 hours.
Hydraulic oil filter: First replacement at 250 hours, then every 500 hours thereafter.
5. WHAT SHOULD BE DONE IF THE EQUIPMENT EMITS ABNORMAL NOISES DURING OPERATION?
Immediately stop operation, identify the source of the noise, and inspect the corresponding components for looseness, wear, or damage. Contact maintenance personnel if necessary.
6. WHAT PARAMETERS SHOULD BE CONSIDERED WHEN PURCHASING TIRES?
Pay attention to specifications, model, ply rating, speed rating, and tread pattern. Select appropriate tires based on the operating environment.
