As a key component of power transmission, the product advantages of crane collectors are mainly reflected in efficient power supply, reliability, adaptability and convenient maintenance. The following is a detailed analysis of its main advantages:
Efficient and stable power transmission
Low contact resistance: Use highly conductive materials (such as copper-graphite composite brushes) to reduce energy loss and improve power supply efficiency.
Continuous power supply: The sliding contact design ensures that there is no risk of power failure during the movement of the crane, avoiding sudden shutdown of the equipment.
Multi-pole integration: Supports three-phase AC or DC multi-pole synchronous power supply to meet the needs of high-power cranes.
High reliability and long life
Wear-resistant design: The collector brush is made of materials such as graphite and copper alloy, which are resistant to arc and mechanical wear and can last for tens of thousands of operations.
Adaptive pressure: The spring or pneumatic mechanism automatically adjusts the contact pressure to compensate for the unevenness or vibration of the busbar.
Anti-fall structure: The collector arm is equipped with a mechanical locking device to prevent the collector brush from detaching from the busbar due to crane vibration.
Wide adaptability
Strong environmental compatibility:
High protection level (IP54 and above), dustproof, waterproof, corrosion-resistant, suitable for harsh environments such as ports and metallurgy.
High temperature resistant models (such as metallurgical grade collectors) can withstand temperatures above 200°C.
Compatible with a variety of busbars: can be matched with copper bars, steel-aluminum composite rails, safety busbars, etc.
Flexible installation: supports top installation, side installation, oblique installation and other methods to adapt to different crane structures.
Convenient and economical maintenance
Modular design: The collector brushes can be replaced individually without disassembling the entire component, reducing maintenance costs.
Status visibility: Some models are equipped with wear indicators or alarm contacts to prompt replacement time.
Low maintenance requirements: Self-lubricating brushes reduce the frequency of manual lubrication and are suitable for high-operation rate occasions.
Safety protection
Insulation protection: The collector housing is made of high-strength insulating material to prevent leakage or short circuit.
Anti-arc design: Special materials or arc extinguishing structures reduce sparks during sliding contact and reduce fire risks.
Overload protection: Linked with the circuit breaker, it quickly cuts off the power supply when the current is abnormal.
Intelligent upgrade (high-end models)
Real-time monitoring: integrated temperature and current sensors, data feedback to the crane control system.
Wireless transmission: some new collectors support wireless status monitoring to achieve predictive maintenance.
