After the installation is complete, install the next section of the air duct, move the scaffolding to the new air duct installation position, and repeat the above operations. This installation method is a combination of manual assembly and manual lifting by the construction workers. The construction efficiency is low, and it is necessary to cooperate with the construction personnel. many
In addition, the air duct installation machinery and equipment are bulky and inconvenient to carry

Description
technical field [0001] The invention belongs to the technical field of building installation engineering, and in particular relates to a ratchet type air duct hoist. Background technique [0002] The air duct installation project inside the building is a very important part of the electromechanical installation project. The air duct is generally located in the upper part of the house, with a relatively high distance from the ground. The entire air duct is composed of multiple sections. Height, first place the air duct on the scaffold, close to its installation height, and then manually lift it up to the precise installation height by several workers, so that the two sections of the air duct are connected, at this time, fix the air duct and between the two sections of the air duct Connection. After the installation is completed, install the next section of the air duct, move the scaffold to the new air duct installation position, and repeat the above operations. This install...
