The motor power of European wire rope electric hoists varies depending on the lifting capacity, working level, and design type. The common power range covers 0.44kW to 45kW, and the specific selection needs to be based on equipment parameters. The following is a detailed analysis of its motor power:

1、 The core influencing factors of motor power

lifting capacity

The lifting capacity is a key factor determining the power of the motor. For example:

1.6 ton class: The lifting motor has a power of 3.2 kW (dual speed design, high-speed 10m/min, low-speed 1.5m/min).

12.5 ton class: The lifting motor power is 12.5 kW (dual speed design, high speed 5m/min, low speed 0.8m/min).

50 ton class: The lifting motor power can reach 38kW or 45kW (single speed design, speed 0-4m/min).

job level

The job level (such as M4, M5, M6) reflects the frequency of equipment usage and load intensity. Higher working levels (such as M6) require larger power motors to cope with frequent start stop and heavy load conditions. For example:

Metallurgical electric hoist (working level M6, lifting capacity 1-16 tons): The motor power needs to be adapted to the high-strength requirements of molten metal lifting.

Universal electric hoist (working level M5, lifting capacity 2-80 tons): The motor power covers 2kW to 45kW, balancing efficiency and cost.

Design Type

Single beam crane: The motor power is usually small (such as 1.6-ton 3.2kW), suitable for light load and high-frequency scenarios.

Double beam crane: The motor power is relatively high (such as 38kW for 50 ton class), and it needs to support heavy loads and long-distance transportation.

Low clearance design: The motor power may be optimized to accommodate compact spaces (such as 12.5kW for the 12.5-ton class) while maintaining lifting height.

2、 Typical motor power configuration

Lifting capacity (ton), motor power (kW), application scenarios

1.6 3.2 (lifting)+0.44 (walking) Lightweight manufacturing, warehouse material handling

12.5 (lifting)+0.96 (walking) medium-sized factories and assembly lines

50 38/45 (lifting)+2 × 1.5 (walking) heavy-duty industrial and port container lifting

3、 The relationship between motor power and performance

Efficiency and energy consumption

High power motors (such as 50 ton 45kW) can enhance single lift capacity, but they consume more energy; Low power motors (such as 1.6-ton 3.2kW) achieve energy savings through variable frequency speed regulation and are suitable for frequent start stop scenarios.

speed control

Dual speed motors (such as 12.5 ton 5/0.8m/min) balance efficiency and accuracy through power switching: high-speed mode is used for long-distance transportation, and low-speed mode is used for precise positioning.

reliability

High power motors need to be equipped with cooling systems (such as IP55 protection level) and braking devices (such as conical rotor braking motors) to cope with overheating and trolley risks under heavy load conditions.

4、 Selection suggestions

Light load high-frequency scene

Choose low-power (such as 3.2kW), dual speed motors that balance efficiency and cost. For example, a 1.6-ton electric hoist is used for warehouse material handling.

Overloading low-frequency scenes

Choose high-power (such as 38kW), single speed motors to ensure stability. For example, a 50 ton electric hoist is used for port container lifting.

Space constrained scenarios

Choose a low clearance design motor (such as 12.5kW) to achieve maximum lifting capacity within a limited height. For example, a 12.5-ton electric hoist is used for lifting inside the factory building.
