Hydraulic lift trimmer: 12 in. (305 mm) hydraulic vertical adjustment with the capability to adjust up to 18 in. (457 mm) with 6 in. (152 mm) manual vertical adjustment.
Optional direct-drive trimmerhead: Trimmerhead is directly driven with a radial piston hydraulic motor which provides a 15 percent increase in torque for more power and a faster tooth-tip rotational speed which moves the trimmed material out of the trimmer box at a higher rate.
CHARGING CONVEYOR

Length: 15 ft. (4.57 m) between pulley centers.
Width: 24 in. (610 mm).
Belt speed: Variable up to 284 fpm (86.6 mpm).
Belt wiper: Features segmented blades mounted on individual cushions. This allows the cleaning tips to conform to the centers of the belt for constant contact without the need for constant adjustment.
Conveyor mount: Features 36 in. (914 mm) hydraulic slide adjustment with 6 in. (152 mm) hydraulic tilt cylinder and manual pivoting mount (slide and tilt) for negotiating discharge from the ready-mix truck and negotiating grade variations. Allows truck positioning to front or side of machine. Hydraulically powered mount controls conveyor slope.
Hopper: Designed for more concrete capacity to allow slipforming complete radius without waiting for concrete delivery.
WATER SYSTEM
Type: Pressurized water system.
Capacity: 100 gal. (378.5 L) water tank with hydraulically driven pressure pump, hose and nozzle.
TRACK SYSTEM
Type: Three hydraulically powered, gear-driven crawler tracks.

Track pad width: 11.8 in. (300 mm).
Gearbox reduction: 100:1 gear reduction with two-speed hydraulic motors.
Track speed: Variable up to 42 fpm (12.8 mpm); auxiliary variable up to 125 fpm (38 mpm).
Track tension: Fully automatic, hydraulically locks in on machine start-up, maintaining a steady tension of the track chain.
Leg height adjustment: Each track has 36 in. (914 mm) hydraulic adjustment and an additional manual adjustment of 8 in. (203 mm).
Telescoping leg for positioning right front track: Hydraulically controlled, allows 24 in. (610 mm) lateral track adjustment range.
Power-slide leg for positioning rear track: Hydraulically controlled, allows up to 40 in. (1016 mm) lateral track movement.
Power-swing pivoting left-front track mount: Hydraulically positions left-front track up to 21 in. (533 mm) to the left or up to 12.25 in. (311 mm) to the right of the straight-ahead position.
DIMENSIONS (Shipping)
