The chassis of the equipment has been engineered to include a four-wheel drive system, providing strong climbing ability. The four-wheel steering system allows for a smaller turning radius, making it especially well-suited for use in tunnel construction projects.

The main arm of the equipment is constructed with a folding and telescopic structure. This design allows for easy transportation and driving, as well as the ability to equip multiple arches for transporting unit A. Additionally, the equipment is adaptable to step construction methods and cross step operations.

The tray of the main arm is capable of transporting multiple arches, with a maximum adjustment distance of 2400mm between the arch clamping mechanism and the inside and outside. This functionality makes it possible to support up to 4 arches at once with a spacing of 800. The tray is capable of multiple degrees of freedom, making it easy to install and adjust the arch.

The auxiliary arm platform is equipped with an arch dragging device, allowing for the main arm to stand on the step arch while also standing on the middle step arch during three step construction. This device assists the main arm in erecting arches on both sides during half section or full section work. Additionally, the towing device can tow the arches from any position on the ground to the platform, and the flexible steel wire rope simplifies docking and bolt connections between the arches.

The linkage mechanism at the end of the main arm, in conjunction with the tray action, can independently install arches on the ground.

The tray of the equipment includes sensing devices and self-memory functions, allowing it to automatically adjust to the initial set leveling state. This feature reduces the time and difficulty of manual adjustment.

An anti-collision warning system and overload warning and protection system have been installed for the boom of the equipment. This system monitors the coordinates and load distribution of the boom in real time, providing reminders and warnings to ensure safe operation of the equipment.

The equipment is equipped with an intelligent fault analysis and diagnosis system. This system monitors and records the operating status of the equipment through various sensing devices. When a malfunction occurs, it can intelligently diagnose the problem or troubleshoot through remote human-machine interaction mode.

The equipment has been designed with advanced electro-hydraulic control technology, which provides better maneuverability and smooth movement with minimal end shaking.

The new product has greatly reduced the number of construction personnel required for its operation. Only 2-3 operators and 2-3 construction personnel are needed. Plus, all construction activities can be done under the supported surface, minimizing the risk of exposure to any hazardous elements.

The equipment features a remote control that is used by the main arm operator to lift the multi-arch forming frame of Unit A to its position, with a drag clamping device in the auxiliary arm supporting the arch frame of Unit B. This way, all the work can be completed without the need for construction personnel to be exposed to any rock surfaces.

The equipment allows workers to save up to 1-2 hours per work cycle due to its different construction techniques and environments. Based on one work cycle per day, this saves 15-30 days per year. Additionally, the equipment only needs a minimum of 3 people and no more than 6 people for operation and construction work, saving a lot of labor costs annually.

Moreover, the equipment only requires the entire arch frame to be divided into three sections, saving the number of connecting plates and bolts, which reduces material costs. The equipment has good mobility and can cover both palm faces, which further saves construction personnel.

The equipment is versatile and can adapt to different construction methods. It can meet the requirements of single arch, multiple arch frames, including multiple double arch frames, and folding arch frames. It can also adjust to tunnel construction with varying cross-sectional sizes, such as high-speed rail double track tunnels and four-lane highways, as well as small section tunnels such as flat guide tunnels, transverse tunnels, and inclined shafts.

The equipment can adapt to various construction methods such as full section, half section, microstep, and three-step tunnels, making it useful for a wide range of construction projects.

In addition to its primary functions, the equipment also has auxiliary capabilities that offer additional functionality. For instance, its three arms and three platforms allow for the main arm platform to expand, making it suitable for explosive cartridge installation tasks.

Plus, the equipment has a maximum lifting height of 12 meters and can carry more than one ton. This feature enables it to be used as an aerial work vehicle for tunnel facility installations and auxiliary operations. It can also be utilized as a truck-mounted crane for lifting, installing, and other lifting operations of the inverted arch.
