Self-propelled machine for delivery of concrete slurry - uses tractor unit and trailer with hopper for wet concrete and screw to raise concrete to centrifugal head

摘要

The machine has two main units linked by a coupling (5) and running on rubber wheels (11,17). The first unit has an engine (7) to provide traction and has a driver's cabin (6) at the front. The second unit has a hopper (12) holding the concrete and a motorised endless screw (14) to raise the wet concrete from the hopper to a centrifugal spreader (13) positioned at the top of the hopper to the rear. The hopper converges at the bottom towards the ground. USE/ADVANTAGE - Ensures stability of wet concrete over longer period, improving quality of concrete lining of tunnels.
