The tunnel maintenance truck newly launched is a special equipment that can transport personnel, instruments, tools and materials to the tunnel. The vehicle is 7.9 meters long, 2.4 meters wide, and 3.9 meters high. It has a maximum operating height of 7 meters and a maximum operating range of 6.7 meters. It is suitable for various tunnel construction maintenance operations or inspection operations.

The whole vehicle is equipped with five work platforms, which are distributed along the tunnel section in a ladder shape, forming a through work channel. The staff can adjust the working position in real time, no need to set up work scaffolding, the flexibility is good, and it can fully meet the needs of tunnel construction.

After the vehicle is deployed, the operation area covers half of the tunnel section at the same time, which can carry more than 10 workers to work at the same time, and the operation efficiency is greatly improved.

The customized working platform can match the working platform space according to the construction characteristics of the tunnel at different heights. It is equipped with a self-propelled system. The construction site is no longer limited to the original site. Even when the vehicle is driving at low speed, it can still operate normally and maintain continuous walking. Work, save work time. It can be operated on both sides, half-width construction can be achieved on one side, and full tunnel section coverage can be achieved on both sides, and multiple angles can meet your construction needs.

The counterweight does not exceed the car body, which can greatly save working space. Only one lane is occupied during operation, and the traffic of adjacent lanes is not affected, and the working environment is safer.
