Tunnel multifunctional arch installation cart

XTGT series tunnel arch installation trucks can adapt to various specifications of steel arch installation, auxiliary loading platform, auxiliary prying hair and ventilation pipe work and other multi-functional, multi-purpose tunnel construction machinery. It can meet the standardization and safety requirements of installing single/multi-bay steel arches (I-beam arch, H-beam arch, steel lattice arch) in railroad and highway tunnels; it can meet the requirements of installing distance of steel arches in single, double and triple excavation of a single hole (full section, step, reserved core soil); according to the needs of users, there are two models, XTGT3 and XTGT2, to choose from. XTGT3 three arms and three baskets, using diesel power for walking, can meet the hole power shortage for construction, with power construction operations, the car four-wheel four-wheel drive, integral chassis, construction stability, three arms and three baskets design, the left and right side wall basket quick-change design, grab the arch flexible, and to meet the needs of the arch of the narrow space, the middle arm of the basket is used for the link bolts, configured with the crushing hammer to deal with the flexibility of underdigging and prying the hair row of risk. The multi-stage telescopic boom is designed to lift 12.8m high and 19m wide.

Main features

High equipment installation efficiency

● Through optimal analysis, the work of the manipulator is minimally designed, which is easy to use, easy to learn and easy to use, and does not worry about finding an operator;

● The boom and manipulator adopt electric proportional control valves, wireless remote control operation, fine control, stable, accurate and fast movement;

● The clamping and moving arch frame personnel are separated from the arch frame unit, which can be quickly moved and assembled without fear of personnel safety issues.;

● 3 hanging baskets and 3 welding machines operate in parallel, with the highest efficiency when welding meshes;

Under the conditions of meeting the corresponding construction method, the three-stage arch frame is installed for 45 minutes, and only 4 to 5 people (including 2 operators) are required for each shift of equipment construction.

Safe

● During the assembly process of the arch frame, the operator only works in the hanging basket when the bolts are connected (there is no connection with the arch frame), and the exposure time of the personnel at high altitude and under the arch frame is the shortest and safer.;

● The middle hanging basket does not participate in the clamping of the arch frame. If there is an emergency, it can be quickly retracted at any time to ensure the safety of personnel.;

● There are 4-5 on-site operators, with few personnel.

Strong adaptability of construction method

● Meet the installation and construction needs of multi-layer arch frames under the full-section construction method;

● Meet the installation and construction needs of multi-layer arches under the step method;

● Meet the installation and construction needs of multi-layer arch frames under the core geotechnical method.

Professional chassis design

● Domestic arch frame vehicles are the first to integrate rock-drilling chassis structure, front box type and rear I-beam frame structure, high strength and good rigidity, rock-solid when working, safe and durable when driving.

● All construction machinery chassis design, four-wheel drive, two-way driving, good passability, puncture-resistant tires, can meet tunnel construction road conditions, equipment transition and transportation are convenient and fast.

● Multi-gear one-button electric shift gearbox (Aerospace power), easy to learn to drive and shift gears, reliable and durable.

The core supporting equipment of the whole machine is of high-end quality, with high reliability and stability

● Cummins brand engine, aerospace power hydraulic transmission;

● Special heavy-duty engineering drive axle, heavy-duty tires:

● Hydraulic system, hydraulic pumps, motors, valves, and cylinders adopt well-known brands at home and abroad;

● CAN bus control system, controller and other important electrical components use domestic and foreign brands.

Focus on humanized design

● The internal maintenance space of the fuselage is large, which is convenient for maintenance;

● Configure two wireless remote controls to operate;

● Three inverter DC welding machines are standard on the vehicle.Reduce homework assistance time.

Accessibility

● The left and right working arms adopt the separate design concept of manipulator grabbing the movable hanging basket, which makes the time for personnel to be exposed to the hanging basket during construction the shortest in the industry. At the same time, when welding the mesh, it cooperates with the fixed hanging basket in the middle to perform multi-basket parallel welding work, and the welding time is the shortest.

● The hanging basket also has the following auxiliary functions: fixing the anchor eye with a steel arch frame, installing the anchor net bolt, welding, charging, measuring, under-digging treatment, ventilation pipe operations, etc.

Safety and environmental protection

● Diesel-electric dual-power system construction system, dual backup of construction power, high reliability, safe, economical, environmentally friendly and low noise of electric motors for construction, diesel engines can also operate in arches when power is lacking or the voltage is unstable, which does not affect the construction period.

Focus on industrial design

● The main color is Jiangxi Xintong family color series one orange + dark gray, the overall appearance is beautiful, generous and harmonious, through the use of high-quality paint, strong adhesion, to ensure that the appearance is timeless.
