automatic tunnel construction robotic arm shotcrete equipment
concrete spraying system description:
The series wet shotcrete system equipments are high-end equipment
with top design and manufacture. They have multi-function and can
be applied widely.
The advantages of the equipments:
1. Hydrostatic running system, rigid chassis, wet mix braking system.
2. Four-wheel transmission, four-wheel steering, small turning
radius, thus make a better operation.
3. Open-type cab, widely views, driver’s seat with 180 º rotation
design, thus make the operation flexible and can drive two-way.
4. Reasonable loading design makes the equipment with bigger
5. Full hydraulic telescope and rotate robot arm make the machine
with high carrying capability, steady movement, flexible operation,
no construction dead zone.
6. Electric motor and diesel two-motor drive.
7. Convey cylinder with long stroke and big cylinder diameter can
reduce the abrasion of resistant ring and plate and improve the
stability of concrete spraying.
8. Hydraulic drive hopper vibrator, air cooler, cable reel,
accelerator pump and water pump can proof electric leakage and
9. The ratio of accelerator and concrete is in fixed and can be
monitored and adjusted by touch screen and remote control.
10. All operation can be controlled by wireless remote control thus
reduce labor intensity and improve working efficiency.
11. Diesel engine can make the spray arms move slowly in case the
concrete solidification makes the equipment crash when electric
power is off.
