How many people are needed to operate the stage hoist?
The stage chain hoist is one of the essential tools for building a stage. How many people are needed to operate it during the lifting process?
In general, a manual hoist only requires a single person to pull the lifting chain, and there are personnel nearby to assist in the lifting and hoisting work. However, if multiple people are needed to operate, we need to be vigilant and check for any operational errors.
The first scenario: The structure of the chain hoist needs to be considered. When the load capacity of the chain hoist is small, the volume of the chain hoist is also relatively small. It only has a zipper strip on one side. However, as the load capacity of the chain hoist increases and the volume increases, in order to improve the safety of lifting, people will set zipper strips on both sides of the chain hoist.
The second scenario is an error in the operation of the chain hoist. For the situation where a chain block with only one zipper strip needs to be pulled by multiple people at the same time, we need to check whether the chain block is overloaded or whether it is safe to use the chain block itself.
Will stage hand pulled gourds also heat up?
Most stage plays are performed at night, but the stage needs to be set up during the day. During the setting process, we may find that the stage hand pulled gourd also heats up. So, how should we deal with this?
Hand pulled hoists rely on human labor to pull the chain for lifting work. Generally, hand pulled hoists do not experience heating, but once discovered, timely response measures need to be taken.
Firstly, when working under direct sunlight, the chain hoist will generate heat. Hand pulled hoists are made of metal, which not only has electrical conductivity but also thermal conductivity. During lifting work, if the hand pulled hoist is lifted under sunlight, it will absorb a large amount of heat, causing the hoist to heat up.
At this point, the operator needs to stop the lifting work and promptly replace the lifting site or build a sunshade.
Secondly, working for a long time in places with high temperatures can also lead to the phenomenon of chain hoist overheating.
