Performance Comparison Between Planetary Hoist and Worm Gear Hoist
1. Motor Function Requirements
For hoists lifting a 630kg load, the planetary hoist uses a 0.88kW motor, while the worm gear hoist uses a 1.5kW motor.
From an economic perspective, as long as it meets customer requirements, the 0.88kW motor is more energy-efficient and eco-friendly than the 1.5kW motor.
Additionally, when used in equipment, the 0.88kW motor has a lower current, reducing cable material costs compared to the 1.5kW motor.
2. Overall Weight and Appearance
The hoists appear as shown in the image below:
- Planetary Hoist (Left)
- Worm Gear Hoist (Right)
a. Weight Comparison:
- Planetary Hoist: 25kg
- Worm Gear Hoist: 48kg
- Difference: Nearly twice the weight
b. Appearance Comparison:
- Planetary Hoist: Compact structure, low space usage
- Worm Gear Hoist: Bulky structure, occupies more space
Overall, the planetary hoist is lightweight and compact, featuring a portable handle that significantly reduces the workload for installation workers—even a woman can install it alone.
3. Rope Winding Performance
- Worm gear hoists are prone to rope jamming, and there is no effective solution to this issue, increasing the risk of hoist casing breakage.
- The planetary hoist features a more compact design that eliminates rope jamming points during steel wire winding, greatly reducing jamming issues, maintenance frequency, and repair costs.
4. Speed Reduction and Transmission Structure
- Worm gear hoists use a worm gear reduction transmission system.
- Planetary hoists use a planetary gear reduction transmission system, which has the following advantages:
- Higher reduction ratio
- Greater transmission efficiency
- Smoother operation
- Longer lifespan
