The lifting weight and rotation radius of a running electric hoist crane are core parameters that directly affect its applicable scenarios and operational efficiency. The following is a specific explanation:

1、 Lifting weight

The lifting weight refers to the maximum load that an electric hoist can safely lift under rated operating conditions. Common specifications and corresponding parameters are as follows:

0.5 tons: with a trajectory rotation radius of 1.5 meters, suitable for light material handling, such as small workshops and warehouses.

1 ton: The trajectory rotation radius is 1.5-4 meters, which can cover medium-sized operations such as mold manufacturing and assembly lines.

2 tons: with a trajectory rotation radius of 2-3 meters, suitable for lifting heavier materials such as mechanical processing and equipment maintenance.

3 tons: The trajectory rotation radius is 2-4 meters, meeting the needs of heavy operations such as construction sites and logistics centers.

5 tons: trajectory rotation radius of 2.5-5 meters, suitable for installation of large equipment and loading and unloading of heavy goods.

10 tons and above: with a trajectory rotation radius of 2.5-7.5 meters, customized design is required for special scenarios such as ports and shipbuilding.

Selection criteria:

It needs to be determined comprehensively based on the maximum weight, frequency, and safety factor of the materials in the homework scenario. For example, when frequently hoisting 2 tons of materials, an electric hoist with a rated lifting capacity of ≥ 2.5 tons should be selected (with a safety margin reserved).

2、 Rotation radius

The rotation radius (working radius) refers to the horizontal distance from the equipment rotation center to the farthest point that the hook can reach, which determines the coverage range of the operation. The common specifications and adaptation scenarios are as follows:

1.5-3 meters: Suitable for working environments with narrow spaces, such as small workshops and warehouses.

3-5 meters: Covering medium-sized work areas such as assembly lines and mold manufacturing workshops.

5-7.5 meters: Meet the needs of large-scale operations such as construction sites, logistics centers, and ports.

Selection criteria:

Homework space: If the homework area is large (such as cross workshop handling), a long rotation radius machine model should be selected; If the space is narrow (such as internal equipment maintenance), short rotation radius models are more flexible.

Installation method:

Fixed type: The rotation radius is fixed, and the scope of work needs to be planned in advance.

Running type: It can be installed on a monorail trolley or cantilever crane, and its position can be adjusted by an electric sports car. The rotation radius can be dynamically changed to adapt to multi station operations.

Factory height: The rotation radius and lifting height need to be matched. For example, when the height of the factory building is 6 meters, it is recommended to choose a lifting height of ≤ 5 meters to avoid the hook touching the top.

3、 Parameter correlation and selection suggestions

Balance between lifting capacity and rotation radius:

The larger the lifting capacity, the smaller the rotation radius (due to structural limitations). For example, the rotation radius of a 5-ton electric hoist is mostly 2.5-5 meters, while a 0.5-ton model can reach 1.5 meters. When selecting, priority should be given to meeting the core parameters according to the job requirements (if lifting 5 tons of materials is required, the rotation radius must be ≥ 2.5 meters).

Speed and accuracy requirements:

Single speed (8m/min): Suitable for scenarios with low speed requirements and average precision requirements (such as ordinary material handling).

Dual speed (8/0.8m/min): suitable for scenarios that require precise positioning (such as mold installation, equipment debugging), achieving millimeter level adjustment through slow speed.

Customized requirements:

If the standard model cannot meet the requirements (such as requiring an extra long rotation radius or special lifting capacity), you can contact the manufacturer for customization. For example, in nuclear power projects, a crane with a turning radius of 28 meters was customized to accommodate the lifting of large equipment.

4、 Typical application scenarios

Small workshop/warehouse: 0.5-2 ton electric hoist with a rotation radius of 1.5-3 meters, used for material handling and equipment maintenance.

Production line/mold manufacturing: 1-3 ton electric hoist with a rotation radius of 2-4 meters, combined with a monorail trolley to achieve multi station operation.

Construction site/logistics center: 3-10 ton electric hoist with a rotation radius of 3-7.5 meters, used for heavy cargo loading and unloading, equipment installation.

Port/Shipyard: Customized models weighing over 10 tons, with a rotation radius of ≥ 7.5 meters, suitable for the lifting needs of large equipment.
