1. Excellent safety and reliability:
Main brake: High-performance disc brake (or cone brake),
responsive, large and adjustable braking torque, good heat
dissipation and long life. Usually normally closed design,
automatic braking when power is off.
Auxiliary brake/safety brake: Some high-end models or specific
requirements will be equipped with a second set of independent
brakes (such as electromagnetic drum or additional disc) to provide
safety protection when the main brake fails.
Overload protection: Integrated mechanical (such as friction
clutch) or electronic overload limiter to prevent overload
operation and protect equipment and personnel safety.
Upper and lower limit limit: Reliable heavy hammer or rotary
encoder type (more accurate) limit switch, automatic cut-off action
to prevent top or excessive lowering.
Phase sequence protection: Prevent the hoist from running in
reverse due to incorrect power phase sequence.
Emergency stop button: Set emergency stop switch on the hoist body
and remote control.
Wire rope anti-slip groove device: Ensure that the wire rope is
properly wound on the drum.
High temperature protection: The motor has a built-in thermal
protection device.
2. Advanced control system:
Modular design: The control box usually adopts a modular design,
which is easy to maintain and upgrade.
Low voltage control: The handle or remote control adopts a safe low
voltage (such as 24V or 36V) control to improve operational safety.
IP protection level: Key components such as the control box, motor,
limit switch, etc. have a high protection level (such as IP54,
IP55), are dustproof and waterproof, and adapt to harsh industrial
environments.
Remote control options: Standard or optional wireless remote
control provides flexible and long-distance operation, improving
the operator's vision and working environment.
3. Convenient maintenance:
Modular design: The main components such as the lifting motor,
reduction box, drum device, and electrical control box adopt a
modular design, which is easy to disassemble, replace and maintain.
Convenient inspection: Inspection covers, oil filling holes, etc.
are set to facilitate daily inspection, lubrication and
maintenance.
Long maintenance cycle: High-quality components and sealing design
usually mean longer maintenance intervals.
4. Standardization and compatibility:
Compliance with international standards: Design and manufacturing
comply with European material handling machinery design standards
such as FEM and DIN, as well as international/national standards
such as ISO and GB.
Easy to integrate: Standardized interface and size design make it
easy to match with various European end beams (or traditional end
beams) to form bridge or gantry cranes.
