Product Uses
1. Bridge and Large-Scale Infrastructure Construction
This crane is ideally suited for tasks such as installing bridge superstructures and lifting large prefabricated components. Its powerful lifting capacity handles diverse heavy-tonnage hoisting demands.
2. Wind Power Equipment Maintenance and Installation
Equipped with dual-ratio Y-type superlift, fixed jibs, and variable-reach jibs, the XCA350 excels in wind turbine maintenance and installation. Its robust lifting performance meets critical hoisting requirements in the wind energy sector.
3. Petrochemical and Heavy Industrial Construction
In petrochemical projects and large-scale equipment installation within heavy industry, this crane excels at lifting large tanks, reaction towers, and process equipment. Its superlift system and intelligent boom control technology ensure stable and safe hoisting operations.
Product Operate Guide
Operating the XCA350 requires a valid Special Equipment Operator Certificate. Before operation, thoroughly inspect the equipment condition to ensure the wire rope, hooks, and safety devices are in good working order. Strictly adhere to the load chart; overloading is strictly prohibited. Maintain smooth and precise movements during operation, remain vigilant of the surrounding environment, and never pass loads over personnel. Conduct regular inspections and maintenance of the hydraulic system. After completing operations, retract the boom to a safe position and disconnect the power supply.
FAQ
1. DURING TILTED OPERATION, DOES THE EQUIPMENT MOVE SLOWLY IN ONE DIRECTION?
This occurs when the spool deviates from center position due to gravity or when internal leakage paths in the actuator change.
2. IS THE REPLACEMENT CYCLE FOR THE PILOT CONTROL OIL CIRCUIT FILTER ELEMENT UNUSUALLY SHORT?
This indicates low efficiency of the main system filter element or accelerated hydraulic oil contamination, allowing fine contaminants to enter the pilot system.
3. IS THE TEMPERATURE OF THE HYDRAULIC PUMP HOUSING RETURN LINE ABNORMALLY HIGH?
Severe internal pump wear increases internal leakage, causing high-pressure oil to leak into the housing where it throttles and generates heat.
4. PRESSURE TEST FITTINGS INSTALLED ON MONITORING PORTS FREQUENTLY FAIL?
Failure to slowly relieve pressure after testing causes instantaneous high-pressure oil impact, damaging the ball valve. Causes include improper operation or poor fitting quality.
5. ACCUMULATOR PRESSURE RETENTION TIME IS TOO SHORT?
The accumulator bladder or diaphragm ruptured, or the charging valve leaks. Recharge with nitrogen or replace the unit.
6. FREQUENT BREAKAGE OF THE SPOOL RESET SPRING IN THE MANIFOLD VALVE?
The spool becomes stuck due to oil contamination. Forced operation by the operator causes the spring to overload and shear.
