It is a special vehicle for bridge inspection personnel to provide a working channel during the inspection, equipped with a bridge inspection instrument for the activity inspection and/or repair work. It can move azimuth at any time, can safely, quickly and efficiently let the inspector enter the work position to conduct activity inspection or repair work. The work does not affect traffic and can travel at a slow speed without retrieving the arms.
The principle is that the hydraulic system bends the work arm deep into the bridge to check the bridge. It's a car chassis and a working arm. There is a spring wind chassis to check the car.
According to the special working equipment, the bridge inspection car is mainly divided into two types: hanging basket and truss type.
The basket bridge checks the car
Hanging basket bridge inspection car, also known as folding arm bridge inspection car, dainty, its structure is conditioned by bridge structure, less sensitive work, also can check the bridge rises to check the bridge superstructure, wired/wireless operation, sensitive and convenient sometimes able to work as a high altitude vehicle utilization, offer relatively low girder bridge inspection car. The basic structure fully embodies the characteristics of the crane truck and the high-altitude working car.
Truss bridge inspection car
Choose leading work channel girder bridge inspection car, good stability, bearing large, when using the inspectors can conveniently from bridge deck into channels or come back, if equipped with elevator can greatly add depth under the bridge.
The bridge is a two-stage, two-stage, two-stage variation, which forms a three-dimensional space with six degrees of freedom. Able to form an independent working channel under the bridge to facilitate the walking of staff. In the chassis, it is equipped with the stability organ, self-propelled supporting casters, fixed weights, the maximum limit ensures the safety of operators. This commodity has the excellent advantages of checking work convenience, not interrupting traffic, working agility, high efficiency, convenient operation and safe reliability.
The domestic current situation of the research and development to produce bridge inspection car: China in the early 90 s and early '90 s, by the ministry of communications of highway planning design institute in Beijing crane QY - 8 truck crane on the basis of design
