Product Uses
1. Construction and Municipal Engineering
This crane is suitable for construction sites and municipal projects, effectively handling the lifting and transport of building materials such as precast slabs and reinforcing bars. Its compact pivot point design minimizes space requirements, facilitating operations in confined areas. The straight boom design also enables more intuitive and flexible operation.
2. Logistics, Warehousing, and Cargo Handling
In logistics yards, warehousing centers, and cargo transfer points, this equipment facilitates cargo loading/unloading and material transport. Its 360° slewing capability meets diverse operational demands in complex conditions, boosting handling efficiency.
3. Mining and Quarrying
This crane can lift minerals, stones, and other materials in mining and quarrying environments. However, special attention must be paid to harsh conditions such as uneven ground and dusty conditions. Strict adherence to safety regulations and enhanced equipment maintenance are essential to ensure safety and suitability.
4. Equipment Installation and Maintenance
In factory and workshop settings, it facilitates heavy-load lifting during equipment installation, maintenance, and repairs. Its pentagonal and hexagonal boom technology optimizes structural design, enhances sectional bending resistance, and ensures stable, reliable operation. The integrated lifting hinge mechanism also extends hydraulic system lifespan and boosts operational efficiency.
Product Operate Guide
Operating the SQ4SK3Q requires a valid Special Equipment Operator Certificate. Conduct a comprehensive inspection of the equipment before operation to confirm the integrity of the wire rope, hooks, and safety devices. Fully extend the outriggers on solid, level ground to ensure stable support. Strictly adhere to the load chart (maximum lifting capacity: 4 tons). Overloading is strictly prohibited. Maintain smooth movements during operation, utilizing the 360° full rotation and four-section boom extension capabilities for precise positioning. Continuously monitor the surrounding environment; never pass loads over personnel. Conduct regular inspections and maintenance of the hydraulic system. After completing operations, fully retract the boom to the transport position and disconnect the power supply.
FAQ
1. HOW TO REPLACE THE HYDRAULIC OIL FILTER ELEMENT?
Shut down the machine and relieve pressure. Clean the area around the filter element housing. Use specialized tools to remove the old element. Install the new filter element, ensuring the seal ring is properly positioned.
