Hydraulic oil cooling: Extra capacity forced-air oil cooler and reservoir designed with internal baffling for atmospheric cooling.
Filtration: Industry standard filtration, including 10 micron return line filter, two 200 mesh magnetic sump strainers and one 20 micron control circuit filter.


Hydraulically powered, motor-in-head, variable speed, independently controlled, and synchronized with machine movement.
Quantity: Four hydraulic circuits and two hydraulic vibrators with mounts included with each machine.


Curb and gutter mold:
One mold standard up to 24 in. (610 mm) wide. Optional molds available for curb and gutter, barrier, parapet, and sidewalk.


Hydraulic lift:
18 in. (457 mm) pressure-compensated hydraulic vertical adjustment with the capability to adjust up to 24 in. (610 mm), with 6 in. (152 mm) manual vertical adjustment.
Sideshift: 48 in. (1219 mm) maximum hydraulic sideshift.


Controls: GOMACO's G+® control system features multi-language capabilities, metric or imperial measurements, color graphics, and a 6.5 in. (165 mm) anti-glare display screen.
Control indicators: Panel-mounted auto control gauges allow operator to monitor control signals as machine follows stringline.
Reverse auto control: Single switch sets controls for automated control with machine traveling in reverse.
Remote control: Tethered remote control handset included for operator convenience.


SUBGRADE TRIMMER (Sectionalized)
Sectionalized trimmer:
Internal hydraulic drive system and 24 in. (610 mm) diameter trimming wheel.
Trimmer wheel rotation: Upward cut.
Width: 30 in. (762 mm) to 66 in. (1676 mm) sectionalized trimmerhead with hydraulic sideshift capability. Right-hand discharge standard.
Sideshift distance: 48 in. (1219 mm) maximum hydraulic sideshift.
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.


Hydraulically powered, reversible with charging hopper. Pivot mount conveyor with hydraulic lift and positioning.
Length: 15 ft. (4.6 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. This allows truck positioning to the front or the side of the machine. Hydraulically powered mount controls conveyor slope.
Hopper: Designed for more concrete capacity to allow slipforming a complete radius without waiting for concrete delivery.


On-board water system.
