The arch installation trolley, also known as the tunnel arch installation trolley, is a multifunctional mechanical equipment specially used in tunnel construction. It can install steel arches, lay steel mesh, and perform other aerial operations. This trolley brings together a variety of aerial work platforms, with strong adaptability and reliability, which can greatly improve work efficiency and reduce labor intensity.
The arch installation trolley is mainly composed of a car chassis, front and rear legs, a subframe, a slide, a mechanical arm, a working platform, a manipulator, an auxiliary arm, a hydraulic winch and other parts. These parts cooperate with each other, allowing the arch installation trolley to complete various complex operations. For example, during tunnel construction, it can easily grab and install steel arches, lay steel mesh, and perform quality inspection, install Fengshui pipes, repair defects, grouting, laying charges and other aerial operations.
According to different usage scenarios, the arch installation trolley is divided into general and special types. The general type is suitable for places without obvious dangerous factors, such as building road tunnels and urban subways. The special type is suitable for places with higher risk factors, such as coal mine tunnels. Regardless of the type of arch installation trolley, it must comply with relevant national standards to ensure the safety and stability of the equipment.
In addition to tunnel engineering, arch installation trolleys are also widely used in high-rise building projects and bridge projects. In high-rise building projects, it can transport heavier building materials such as concrete, reduce the hard work of manual handling, and improve work efficiency. In bridge projects, it is mainly used to transport and carry large and heavy materials such as steel beams and steel plates. Because bridges have various shapes and materials need to be transported at different heights and angles, the arch installation trolley can adjust the height and angle to better adapt to different working environments.
Using an arch installation trolley can not only improve construction efficiency, but also improve construction quality. Its mechanical arm and gripper design are very advanced, which can accurately grasp and install various materials and reduce manual operation errors. Moreover, the arch installation trolley is also equipped with auxiliary equipment such as telescopic hanging basket, breaker and welding machine, which can well complete various operations in construction.
In addition, the arch installation trolley greatly reduces the number of operators. In the past, traditional tunnel construction required a lot of workers to carry and install manually, which was labor-intensive and had safety hazards. With the arch installation trolley, the entire construction work can be completed by only 3-4 people, which not only reduces labor costs but also improves work safety.
