Technical Field

[0001] The utility model relates to a large scissor arm installation tool and belongs to the technical field of large scissor arm installation. Background Art

[0002] During the installation of the large scissor arm of the lift, the installation of the large scissor arm requires high-precision alignment and fixation. If the precise installation position and angle are not ensured during the installation process, the lift may shake, deflect or become unstable during the lifting process, thus affecting the lifting effect and safety. If the connectors between the large scissor arm and the lift body, such as pins and bolts, are improperly installed or insufficiently tightened, they may become loose or fall off, causing equipment failure and safety accidents. During the installation process, if the arm is subjected to improper force or impact, it may deform or twist, thus affecting the stability and lifting accuracy of the lift. The operating skills and safety awareness of the installer have a direct impact on the installation quality. Improper operation, such as using inappropriate tools and not following the correct installation steps, may lead to installation defects.
