[0030] The parallel steel beams are arranged in parallel on one side of the long-span steel beam 5. The parallel steel beams include longitudinal parallel steel beams 1 and transverse connecting rods 2. The two ends of the transverse connecting rod 2 are respectively connected to the web of the long-span steel beam 5 and the longitudinal parallel steel beam 1.

[0032] Specifically, during the operation of the device, the hoisting process of the ultra-long-span light steel structure beam does not require blindly increasing hoisting equipment, and can ensure that the steel beam can be normally hoisted upright, and the hoisting operation can be completed safely, quickly and accurately.
[0033] In some embodiments, the length extension direction of the longitudinal parallel steel beam 1 is consistent with the length extension direction of the long-span steel beam 5.
[0034] In some embodiments, the longitudinal parallel steel beam 1 is made of I-beam (such as 14# I-beam), and the I-beam is installed horizontally.
[0035] In some embodiments, the length of the longitudinal parallel steel beam 1 is the same as the length of the long-span steel beam 5, and the slope of the longitudinal parallel steel beam 1 is the same as the slope of the top surface of the long-span steel beam 5.

The above dimensions can be freely adjusted according to the actual situation on site and the weight and dimensions of the hoisted steel beam.
[0045] The beneficial effects that the present application can produce include:
[0046] The parallel steel beam hoisting device for the super-long-span light steel structure beam provided by the present application adopts the principle of parallel steel beams.

[0047] In addition, the hoisting device adopts the stabilizing suspension point technology, adding a truck crane for cooperation and stabilization, avoiding the overturning and instability of the long-span steel beam from the ridge position, ensuring that the steel beam can be lifted upright normally. Using this device can assist the hoisting operation of the long-span steel beam in a limited space, greatly improving the safety of the hoisting process, reducing the investment in hoisting equipment, and improving work efficiency.
