Double Beam European Electric Hoist

 Double Beam European Electric Hoist's hallmarks include lightweight construction, modular design, and a maintenance-free ethos. At its core lies a precision-engineered German-imported lifting motor and reducer, seamlessly integrated into a compact unit that houses the drum and lifting limit switch. This design not only optimizes user space but also reinforces reliability while significantly curbing maintenance expenses. Furthermore, it offers expedited lifting speeds and a range of pulley ratios for utmost versatility. The standard trolley operation mechanism, equipped with a frequency converter control system, achieves speeds of up to 20 meters per minute, ensuring the precise and secure transport of delicate and valuable loads with minimal sway and pinpoint accuracy.

 

 

The design adheres rigorously to the pertinent FEM standards.

● Technical Features of the Lifting Mechanism:

■ Aluminum alloy reducer housing

■ Silky-smooth operation with minimal noise

■ Lifetime lubrication (within the prescribed safe operating period)

■ Dual-disc electromagnetic brake for added safety

 

1. Drum: Crafted from high-grade seamless steel pipe via CNC machining, the drum boasts precision-engineered rope guide to prevent rope entanglement effectively

 

2. Wire Rope: Employing high-strength imported wire ropes with a tensile strength of 2160 N/mm² ensures both safety and an extended service life.

 

3. Rope Guide: Standard rope guides, constructed from engineering plastics renowned for their robust wear resistance and excellent self-lubricating properties, dramatically reduce wear on the wire rope, thus augmenting the safety of the lifting mechanism. For more demanding usage scenarios, heavy-duty rope guides crafted from nodular cast iron can be made available.

 

4. Lifting Motor: The lifting motor features a dual-winding squirrel-cage variable-pole motor, achieving an impressive 1:6 speed ratio. Its aluminum alloy housing facilitates efficient heat dissipation, complemented by a fan for enhanced cooling. Thermal resistors (or thermal switches) are embedded in all lifting motors to thwart overheating. The motor boasts an insulation class of F and a protection class of IP54. Variable-frequency lifting motors can incorporate encoders, typically mounted directly on the motor's fan shaft.

● Motor Technical Features:

■ Low starting current, high torque

■ Soft start for exceptional acceleration

■ Extended design service life

■ Technical parameters align with FEM and HMI standards

■ High speed with minimal noise

 

5. Brake: Equipped with dual-disc electromagnetic brakes, the lifting motor's integrated brake engages automatically upon de-energization, preventing load slippage. Once the brake interval is initially set, no manual adjustments are necessary (interval is self-adjusted via brake springs). An additional monitoring switch automatically alerts users when the brake pad thickness falls below the preset value. The dual-disc electromagnetic brake guarantees safety and reliability, delivering 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, all without requiring maintenance.

● Brake Technical Features:

■ Swift response with high reliability

■ Maintenance-free and self-adjusting

■ Dustproof design for extended service life

 

6. Reducer: The reducer housing, composed of lightweight and corrosion-resistant aluminum alloy material, encases semi-fluid lubricants, ensuring ample lubrication of all gears without the need for lubricant replacement within the designed safe operating duration. Each gear undergoes surface hardening and high-precision grinding treatment to ensure the smooth operation of the reducer.

● Reducer Technical Features:

■ Compact dimensions and lightweight design

■ Smooth and quiet operation

■ Corrosion resistance with minimal maintenance requirements

 

7. Safety Protection

● Precise gear-driven limiters govern the upper and lower limits of wire rope electric hoists, guaranteeing the disconnection of the power circuit and halting the electric motor when the hook reaches the upper (or lower) limit position.

● Electronic overload protectors, complete with safety monitors, are employed to ensure that the cumulative lifting weight remains within the crane's rated lifting capacity. Should the tension in the wire rope exceed 105% of the rated value, this overload protection device will automatically deactivate the lifting circuit.

● Optional safety monitor functions can be tailored to user preferences:

■ Calculation of remaining safe working cycles for the lifting mechanism

■ Accumulation of lifting working time

■ Compilation of overload instances

■ Tally of lifting motor startups

■ Overheating protection and alarms for the lifting motor

■ Overload protection and alarms

■ Brake pad thickness alerts

■ Display of fault information and maintenance prompts

 

• The traveling mechanism adopts a "motor + reducer + trolley wheel" three-in-one structure, featuring dual-side drive on the double-beam trolley frame.
• Variable-frequency speed control ensures smooth operation, minimizes load sway during transportation, enhances safety, reduces operation cycle time, and boosts production efficiency.
• All bearings are self-lubricating with oil-containing designs, effectively absorbing horizontal forces.
• Surface-carburized and hardened gears, with gear grinding or shaving for noise reduction, are employed throughout the reducer. Gearboxes do not necessitate oil changes during their service life.
• The brake's reliability surpasses 1 million cycles.
• The entire travel mechanism boasts an IP54 protection rating, while the drive motor's insulation class is F.
• The entire system is engineered for maintenance-free operation.
