RF-M Suspended

Features

• The crane's classification standards are CNS Class C, DIN 2m, and ISO M5.
• Motor dustproof and waterproof rating: IP54
• Motor insulation class F
• The motor is rated for operation at S1 and features overheat protection with automatic stop and reset.
• Test load > 125%
• Braking torque > 150%
• Attached are test reports and factory certificates.

Appearance

• Low headroom design, takes up little space.
• The rigid shell design eliminates vibration and noise generated under load.

Brake 

• The main crane brake uses an AC electromagnetic brake, which has a faster response speed than a DC brake.
• It has a manual release function.
• Both the main crane brake and the traverse brake are designed so that they can be adjusted using only a single bolt.

Optional – Electromagnetic auxiliary safety brake, which prevents the brake from opening when the motor is not powered, ensuring safety.

Roll design The 42-hook design ensures that the hook remains centered during lifting and lowering, guaranteeing safe positioning.

• The roll comes with strength calculations and material certificates.

Security features

• A suspended push-button switch with an emergency stop function.
• Automatic stop function at the upper limit position of the hook.

Power supply phase loss and reverse direction protection functions.

Optional – The guide cable can also have an automatic stop function at the lower limit position of the hook.

Optional – Overweight protection device; if digital, it can also be used as a weight display.

Gearbox Design

• The casing is made of cast iron to reduce noise and uses ground gears.
• Gearbox material = FCD45

Hook design

• Safety factor > 5.。
• Equipped with a thrust bearing, it can be manually rotated 360 degrees under full load.
• Attached are test reports and material certificates.
• Optional – VType of hook: This increases the length of steel cable that the drum can hold and optimizes the angle at which the steel cable is wound into the drum.

Double-rail trolley – self-aligning  The design allows for eccentricity of the driven trolley axle, overcoming track laying errors.

Control method: Suspension-type push-button switch

Power requirements: 3-phase 220/380/415/440/460V 50/60Hz

Optional    

1. Gear-type upper and lower limit devicesIt can prevent reverse winding or over-winding.
2. Speed ​​controlOptional features include: main hoist with dual-speed control for horizontal and vertical travel, stepless speed change, soft start and stop, etc.
3. Radio Remote Controller: Can perform remote control.
4. Rope GuideMade of spheroidal cast iron, it is wear-resistant, tensile-resistant, and temperature-resistant.
5. Overload protection device for steel cablesOverload alarm and stop device.
6. Forced cooling fanA forced air diffuser is installed on the brake side of the motor, which is suitable for high-temperature environments or frequent lifting of cranes, and can effectively extend the life of the motor and brake.
