When choosing a running electric hoist, it is necessary to comprehensively consider the six core elements of load capacity, operating environment, track adaptability, control mode, safety performance, brand and after-sales service. The specific selection method is as follows:

1、 Clearly define load requirements

Lifting capacity: The minimum lifting capacity is determined by multiplying the total weight of the material, packaging, and lifting equipment (such as hooks and fixtures) by a safety factor (usually 0.7). For example, when the total weight of the material is 3 tons, an electric hoist of 4 tons or more should be selected.

Lifting height: It is necessary to specify the effective lifting height, which is the distance from the ground or designated reference point to the highest position of the hook. The high lifting scenario requires selecting a model that is compatible with the length of the drum or chain.

2、 Evaluate the operating environment

Temperature and humidity: High temperature environments require high-temperature resistant motors, while humid environments require waterproof and dustproof ratings (such as IP55 or above).

Corrosive gases: Corrosive environments such as chemical and coastal areas require the use of anti-corrosion electric hoists, such as stainless steel materials or special coating treatments.

Explosion proof requirements: Explosive and flammable places (such as petrochemicals and coal mines) must choose explosion-proof electric hoists that comply with explosion-proof standards such as Ex d IIB T4.

3、 Track design and adaptability

Track type: Choose I-beam track or lightweight track according to the working conditions. I-beam track should be matched with models 16 # -45 #, and lightweight track is suitable for low load scenarios.

Span and curvature:

The span of a simply supported straight track should be calculated based on the spacing between the supporting beams to avoid track deformation.

The curved track should be designed according to the curvature radius of the electric hoist wheel tread (such as 129mm for less than 1 ton and 167mm for 5-10 tons).

Wheel pressure and stability:

Calculate the standard value of concentrated load on wheels (including maximum lifting weight and self weight of electric hoist) to ensure the bearing capacity of the track.

The track model is controlled by the envelope of strength, stability, deflection, and converted stress. For large-span (>6m) or small-sized tracks (<25 # I-beams), stability verification should be emphasized.

4、 Control mode and efficiency

Transfer speed:

Single speed is suitable for simple lifting, while dual speed or variable frequency control can meet precise positioning requirements (such as assembly lines).

Variable frequency electric hoist can achieve stepless speed change, improving operational flexibility.

Running the car:

Fixed type is suitable for fixed-point lifting, and electric trolley type supports left and right walking, expanding the scope of operation.

The running speed of the car needs to match the lifting speed to avoid efficiency bottlenecks.

5、 Security performance and additional features

Extreme protection: equipped with upper and lower limit switches to prevent the chain or wire rope from over winding.

Braking system: A dual braking system (such as a conical rotor brake motor) ensures stable suspension of the hook when power is cut off.

Overload protection: Automatic power-off function prevents overload operation and extends equipment life.

Additional functions:

Wireless remote control improves operational convenience.

LED lighting is suitable for nighttime or low light environments.

The magnetic remote control and foldable hook are designed to optimize storage and user experience.

6、 Brand and after-sales service

Brand selection:

Imported brands such as DEMAG and KONECRANES have stable performance but higher prices.

Domestic brands such as Hugong and Franktek have high cost-effectiveness and are suitable for budget limited scenarios.

After sales service: Priority should be given to brands that provide nationwide warranty and rapid response services to reduce maintenance costs in the later stage.
