Adroit 450H/W 4x4 Shotcrete Machine

Product catalog summary

Overview: The Adroit 450H/W series is a versatile 4x4 shotcrete machine designed for concrete pumping and shotcreting. It features a rigid chassis with four-wheel drive and steering, making it suitable for challenging terrains. The machine is equipped with a lifting, tilting, and telescopic boom system, along with various pumps and tanks for efficient operation.

Specifications: The machine has a standard pumping capacity of 30 m3/h, with adjustable concrete pumping capacity. It supports a maximum pumping pressure of 70 bar and hydraulic pressure of 250 bar. The aggregate size can be up to 16 mm, and it can pump all types of fibers. The dimensions are 7750 mm in length, 2350 mm in width, and 3000 mm in height, with a weight of 10100 kg.

Drive Systems: Two drive systems are available: hydrostatic and powershift. The hydrostatic system provides maximum torque with variable flow pump and hydromotor, ideal for high-speed performance and difficult ground conditions. The powershift option offers enhanced movement ability for long distances.

Concrete Pump: The machine includes a diesel engine-driven concrete unit cleaning system, hydraulically driven hopper vibrator, and a hydraulically controlled hopper drain cover. The concrete line diameter is 76 mm.

Accelerator System: Features an electrically driven accelerator peristaltic pump with a dosing rate of up to 20 L/min and a maximum pumping pressure of 15 bar. The accelerator tank capacity is 1000 L.

Operator Cabin: The cabin is FOPS-ROPS level 2 certified, with tempered glasses, a suspended and 180° pivoting seat, and a retractable lap seat belt.

Compressor: Equipped with an electrically operated screw compressor with a capacity of 9.2 m3/min and a pressure of 8 bar, powered by a 55 kW electric motor.

Engine: The machine is powered by a Perkins 1104D - 44T 74.5 kW diesel engine, compliant with EU Stage 3A standards.

Axle and Transmission: The hydrostatic system features a planetary type Dana 212 with an oscillating rear axle, while the powershift system includes a planetary type Dana 212 with an oscillating front axle. Both systems offer four-wheel drive with different speed and gradient capabilities.

Performance: The hydrostatic option allows a maximum speed of 28 km/h and a climb gradient of 50%, while the powershift option offers a maximum speed of 30 km/h and a climb gradient of 40%.

Brake System: Includes hydraulically powered two-circuit oil-immersed multidisc brakes and a fail-safe parking brake.

Steering: Offers four-wheel steering, crab steering, and front-wheel steering options.

Fuel and Hydraulic Systems: The fuel tank capacity is 150 L, and the hydraulic system includes a 250 L tank with filtration and fluid level sensing.

Electrical Systems: Features IP65 protection grade components, a 24VDC system, and a high voltage electrical system with a 45 kW power pack.

Optional Components: Includes a Perkins 904J - E36TA engine, fire suppression system, catalytic converter, radio remote control, automatic lubrication system, air conditioning, and more.

Boom System: The boom system allows for lateral movement of 13.1 m and vertical movement of 15.2 m.

High Pressure Water Washer: Equipped with a water pump delivering 14 L/min at a maximum pressure of 200 bar, with a 300 L tank capacity.

Catalog excerpts

Adroit 450H/W4x4 Shotcrete Machine i^TUNELMAKi Adroit 450H/W series are designed as concrete pumping and shotcreting machines. The rigid chassis has 4 wheel drive and 4 wheel steering. Machines are fully equipped with lifting, tilting, telescopic boom system, rotation group, compact modular system, water & admixture pumps and tanks, energy cable reel, compressor on the platform. Standard pumping capacity is 30 m3/h, concrete pumping capacity is adjustable. Hydrostatic and powershift drive systems are available for this machine. Hydrostatic system allows user to have max. torque by variable flow pump and hydromotor. According to road and land conditions, gear options can be chosen as fast or slow. Ideal choice for work sites where high speed performance is required and construction areas, which have difficult ground conditions. Powershift option provides more movement ability in long distance.
