[0002] Hoisting operation is commonly used in large-scale engineering operation, and strutting bar, as an important tool for hoisting, has been widely used in various large-scale lifting processes. However, with the increasing size of single equipment or device, conventional strutting bar cannot meet the engineering needs. For example, due to the limit of single row hoist, if the equipment or device exceeds the limit of single row hoist, two row hoists need to be used together, and there is a minimum span requirement between the row hoists. If the span of the lifting device is less than the minimum span of the row hoist, the two row hoists will produce a diagonal pull, which is not allowed in engineering. For such devices, a truck crane is often used with a row hoist to reduce the span requirement, but this solution increases the cost of lifting and prolongs the construction period of the equipment.
[0003] The existing strutting bar cannot be adjusted in length to adjust the span, which requires a lot of time to select the appropriate strutting bar or to modify the site before each lifting operation to meet the fixed span requirement of the strutting bar.
