Concrete construction/readymix/placement: Advance front-discharge ready-mix concrete truck delivers and places concrete in trench. The mechanisms that position the concrete placing chute are all controlled by the truck driver from his driving position, which allows him to continually position truck and chute in the best placement location while placing concrete.
Chute control mechanisms include the following: 1. Top of chute, where concrete is fed into chute, can be rotated horizontally through 180+ degrees with horizontal chain drive around chute top gear, to place concrete at any angle to side or in front of truck. 2. Hydraulic piston at vertical angle from truck front center supports and positions 1st section of chute vertically. 3. Hydraulic pistons parallel to chute on both sides at joints between sections 1 and 2 and sections 2 and 3 fold chute up out of driver's way when truck is driven to and from job.
