Description

Technical Field

[0001] The utility model relates to the technical field of channel hoisting equipment, in particular to a double-beam gantry crane special for hoisting channel side plates. Background Art

[0002] The construction of water channels is mainly done by connecting prefabricated channel side panels to the channel bottom plate. During the connection process, lifting equipment is used to lift and install the channel side panels to the designated position of the channel bottom plate. During the connection process, high lifting accuracy is generally required to ensure the smooth installation of the channel side panels.

[0003] Existing channel hoisting equipment (such as the CN221027301U - a large-scale prefabricated reinforced concrete rectangular channel dedicated gantry crane) cannot accurately control the crane's position during the hoisting process. This makes the docking and installation of the channel side panels difficult and slow, affecting the construction schedule. Therefore, a channel hoisting equipment with precise positioning is needed.
