Single Beam European Electric Hoist

It utilizes a German-imported lifting motor and reducer. The integrated compact design of the lifting motor, reducer, drum, and lifting limit switch saves user space. The modular design enhances reliability while effectively reducing maintenance time and costs. It offers faster lifting speeds and a variety of pulley ratios to choose from. The standard trolley operation mechanism uses a frequency converter control, with a speed of up to 20 meters per minute, allowing for precise and safe transportation of delicate and valuable items with minimal swinging and accurate positioning.

 

 

The design strictly adheres to relevant FEM standards.

● Technical Features for Lifting Mechanism:

■ Aluminum alloy reducer housing

■ Smooth operation, low noise

■ Lifetime lubrication (within the safe operating period)

■ Dual-disc electromagnetic brake

1. Drum: The drum is machined from high-quality seamless steel pipe using CNC machines, and precision machining of the rope guide effectively prevents loose and tangled ropes.

2. Wire Rope: High-strength imported wire ropes with a tensile strength of 2160 N/mm² are used, ensuring safety and long service life.

3. Rope Guide: Standard rope guides are made of engineering plastics with strong wear resistance and good self-lubricating properties, significantly reducing wear on the wire rope, thereby enhancing the safety of the lifting mechanism. For different usage conditions, heavy-duty rope guides made of nodular cast iron can also be provided.

4. Lifting Motor: The lifting motor uses a dual-winding squirrel-cage variable-pole motor, achieving a 1:6 speed ratio. The motor housing is made of aluminum alloy, providing excellent heat dissipation, and a fan is installed at the end of the lifting motor to enhance cooling. All lifting motors are embedded with thermal resistors (or thermal switches) to prevent overheating. The motor insulation class is F, and the protection class is IP54. Encoders can be added to variable-frequency lifting motors, typically installed directly on the motor's fan shaft.

● Motor Technical Features:

■ Low starting current, high torque

■ Soft start, excellent acceleration performance

■ Long design service life

■ Technical parameters comply with FEM and HMI standards

■ High speed, low noise

 

5. Brake: The lifting motor is equipped with dual-disc electromagnetic brakes. The brake is integrated at the motor's end, and when the motor is de-energized, the brake automatically engages to prevent load slippage. Once the brake interval is set initially, no manual adjustment is required (intervals can be self-adjusted by brake springs). An additional monitoring switch automatically alerts users when the brake pad thickness is below the set value. The dual-disc electromagnetic brake is safe and reliable, with a braking torque of at least 1.8 times the motor's rated torque and a braking cycle of up to 1 million times within the safe operating period, with no maintenance required.

● Brake Technical Features:

■ Quick action, high reliability

■ Maintenance-free, self-adjusting

■ Dustproof design, long service life

 

6. Reducer: The reducer housing is made of aluminum alloy material, lightweight and corrosion-resistant. The fully sealed housing contains semi-fluid lubricants, ensuring sufficient lubrication of all gears, with no need for lubricant replacement within the design's safe operating period. Each gear, after surface hardening and high-precision grinding treatment, guarantees smooth operation of the reducer.

● Reducer Technical Features:

■ Small size, lightweight

■ Smooth operation, low noise

■ Corrosion-resistant, maintenance-free

 

7. Safety Protection

● The upper and lower limits of wire rope electric hoists use precise gear-driven limiters that reliably cut off the power circuit and stop the electric motor when the hook reaches the upper (or lower) limit position.

● Overload protection: Wire rope electric hoists use electronic overload protectors (with safety monitors) to ensure that the total lifting weight does not exceed the rated lifting capacity of the crane. When the tension in the wire rope exceeds 105% of the rated value, this overload protection device will automatically cut off the lifting circuit.

● Safety monitor (optional): Various functions can be implemented according to user requirements:

■ Calculate the remaining safe working cycles of the lifting mechanism

■ Accumulate lifting working time

■ Accumulate overload occurrences

■ Accumulate lifting motor start-ups

■ Overheating protection and alarms for the lifting motor

■ Overload protection and alarms

■ Brake pad thickness alarms

■ Display fault information and maintenance prompts

 

1. The traveling mechanism adopts a "motor + reducer + trolley wheel" three-in-one structure, with dual-side drive on the double-beam trolley frame.
2. Variable-frequency speed control for smooth operation, reducing sway during load transportation, enhancing safety, reducing operation cycle time, and improving production efficiency.
3. All bearings are self-lubricating with an oil-containing design, effectively absorbing horizontal forces.
4. All gears in the reducer are surface-carburized and hardened, and for noise reduction, all gears must undergo grinding or shaving. The gearboxes do not require oil changes within their service life.
5. The reliability of the brake exceeds 1 million cycles.
6. The entire travel mechanism has an IP54 protection rating, and the insulation class of the drive motor is F.
7. The entire mechanism is designed for maintenance-free operation.
