Equipped with a professional telescopic arm high-altitude operation device, the maximum operating height can reach 32 meters, achieving comprehensive coverage of mid to high altitude operations. It accurately matches the needs of mid to high altitude operations such as power repair, communication maintenance, street lamp maintenance, and billboard installation, without the need for additional scaffolding, greatly improving operational efficiency and adapting to most medium-sized high-altitude operation scenarios. The homework arm can be flexibly extended and retracted, and the work bucket supports 360 ° rotation. It is equipped with front V and rear H-shaped hydraulic telescopic legs (including up and down, horizontal bidirectional extension, a total of eight oil cylinders). The legs can flexibly adjust the support angle and span, which can effectively avoid obstacles on the work site and adapt to complex work environments such as urban streets, factory areas, and communication base stations, further expanding the coverage of the work. The rated load of the work bucket is suitable for 1-2 workers and the required tools to work synchronously, without the need for repeated up and down trips, reducing work time and improving work continuity; The equipment configuration conforms to the factory standards, and can be adapted to the passenger and cargo requirements of different work scenarios according to actual needs, enhancing the practicality of the equipment. The work arm is made of high-strength materials, with a sturdy structure and strong deformation resistance. It is equipped with a reliable hydraulic control system and leveling device to ensure that the work platform remains level during the operation process, avoiding tilting of the work surface due to the extension and rotation of the arm frame, ensuring work accuracy and personnel safety, and adapting to long-term high-frequency work needs.
