The lifting capacity and rotation radius of an operational manual hoist (usually referring to a manually operated chain hoist or a hoist used in conjunction with a manual monorail) need to be analyzed based on specific equipment types and configurations. Its core parameters and characteristics are as follows:

1、 Range of lifting capacity

Conventional manual hoist lifting capacity

The lifting capacity of a manual hoist is usually between 0.5 tons and 50 tons, depending on the model and design.

Small tonnage (0.5-3 tons): suitable for light lifting operations, such as auto repair, warehouse cargo handling, etc., which can be operated by one person.

Large tonnage (5-50 tons): Used for heavy equipment installation, construction sites, and other scenarios, requiring multiple people to cooperate in operation (such as 2 people recommended for zippers weighing over 5 tons), and ensuring even tension during operation to avoid chain jamming or jumping.

Additional limitations of the running gourd

If a manual hoist is used in conjunction with a manual monorail (forming a hand pulled heavy transport trolley), its lifting capacity is also limited by the load-bearing capacity of the monorail. For example, the rated load of a monorail may be 1-10 tons, and the matching hoist model needs to be selected according to actual needs.

2、 Rotation radius (applicable coverage range of the scene)

The rotational ability of the manual hoist itself

The manual hoist itself does not have active rotation function, and its "rotation radius" usually refers to the coverage range of supporting equipment (such as cantilever cranes, monorail cranes).

Cantilever crane configuration: If a manual hoist is installed on a cantilever crane, the rotation radius of the cantilever (i.e. the length of the cantilever) determines the operating range. For example, when the cantilever length is 2-5 meters, the rotation radius is within this length range, which can cover the lifting requirements within a fixed area.

Monorail configuration: If a manual hoist is used in conjunction with a manual monorail, the track length and layout of the monorail determine the scope of operation. For example, when the track length is 10 meters, the hoist can move along the track to cover lifting operations within a 10 meter range.

Rotation requirements for special scenarios

In narrow spaces or scenarios that require flexible adjustment of work positions, different lengths of cantilevers or tracks can be selected to meet the rotation radius requirements. For example, in auto repair shops, short cantilevers (2-3 meters) combined with manual hoists can cover the lifting needs of vehicle maintenance areas.

3、 Key operating standards and safety requirements

Weight limit

Overloading is strictly prohibited, and the matching hoist model should be selected based on the weight of the goods. For example, when lifting 2 tons of goods, a manual hoist with a rated load of ≥ 2 tons needs to be used.

When operating a large tonnage hoist (such as 5 tons or more), multiple people need to cooperate, and the zipper direction should be in the same plane as the sprocket to avoid chain jamming or jumping caused by diagonal pulling.

Rotating radius safety

If the hoist is installed on a cantilever crane or monorail, it is necessary to ensure that the cantilever or track is firmly fixed to avoid equipment overturning due to rotation or movement.

During rotation or movement, it is necessary to keep the work area clear of obstacles to prevent collision or compression risks.

Maintenance and Inspection

Regularly inspect the wear of key components such as chains, hooks, and braking devices to ensure that the equipment is in good condition.

Before each use, it is necessary to conduct no-load and heavy load tests to confirm normal operation before putting it into use.
