The arch frame trolley, also known as a tunnel arch installation trolley, is a multifunctional mechanical device specifically used for installing steel arches, laying steel mesh, and other high-altitude tasks in tunnel construction. It integrates various high-altitude work platforms, offering strong adaptability and reliability. This significantly enhances work efficiency and reduces labor intensity.
The arch frame trolley mainly consists of an automotive chassis, front and rear support legs, subframe, sliding platform, mechanical arm, working platform, manipulator, auxiliary arm, hydraulic winch, and other components. These components work in synergy, enabling the arch frame trolley to perform various complex tasks. For example, in tunnel construction, the arch frame trolley can easily grab and install steel arches, lay steel mesh, and carry out quality inspections, ventilation pipe installation, defect repairs, grouting, and explosive charge setups.
Depending on the application scenario, arch frame trolleys can be divided into general and special types. General arch frame trolleys are mainly suitable for environments without significant danger factors, such as road tunnels and urban subways. Special arch frame trolleys, on the other hand, are primarily used in more hazardous environments, such as coal mine tunnels. Regardless of the type, all arch frame trolleys must adhere to relevant national standards to ensure equipment safety and stability.
In addition to tunnel engineering, arch frame trolleys also find wide applications in high-rise building and bridge engineering. In high-rise building projects, arch frame trolleys can be used to transport heavy construction materials like concrete, reducing manual handling labor and increasing work efficiency. In bridge engineering, arch frame trolleys are mainly used to transport and handle large and heavy materials such as steel beams and plates. Due to the varied shapes of bridges, materials need to be moved at different heights and angles, so arch frame trolleys feature adjustable heights and angles to better adapt to different work environments.
The use of arch frame trolleys not only improves construction efficiency but also enhances construction quality. With advanced mechanical arm and gripper designs, they can precisely grasp and install various materials, reducing human error. Additionally, arch frame trolleys are equipped with auxiliary devices like extendable baskets, hammers, and welding machines, ensuring various tasks in the construction process are well-executed.
Moreover, arch frame trolleys significantly reduce the number of personnel required. Traditional tunnel construction often requires a large number of workers for manual handling and installation, which is labor-intensive and poses safety risks. The advent of arch frame trolleys allows the entire construction operation to be completed by just 3-4 people, greatly lowering labor costs and improving work safety.
