FOUR-TRACK CONCRETE PLACER-SPREADERAUTOPLACE PS-6
The PS-6 model leads the world’s highest capacity paving trains.
All of CMI’s material placing equipment is designed for demanding operations across diverse applications found in the four corners of the world. Variable-width placing and spreading.
- Dual-lane spreading in a single pass
- Hydrostatic-driven rotary-spreader auger and strike-off moldboard assemblies adjust for crowning
FEATURES
Drive System
Dual-range propelling system with variable hydrostatic drives for both forward and reverse. Paving range variable up to 30 fpm (9 mpm). Trimming range variable up to 60 fpm (18 mpm). Travel range variable up to 60 fpm (18 mpm).
EDC-controlled track drive and auger drive for improved control of hydrostatic functions.
Tracks are driven hydrostatically through deep-reduction planetary hubs. Posi-Trac® 4-track control limits track slippage. Track length 8 ft 4 in (2.54 m), 28 in (7112 mm)-deep section. D-4 undercarriage components with 18 in (457.2 mm) triple-grouser street shoes. 10 in (254 mm) leg barrels with 42 in (10668 mm) vertical stroke.
Mainframe
Deep section, telescoping mainframe is hydraulically adjustable up to 8 ft (2.44 m), providing placing and spreading width ranges from 18 ft to 24 ft (5.49 m to 7.32 m), standard. Optional extensions expand spreading width to 38 ft (11.58 m).
Power Drive System
Five axial piston-type hydrostatic pumps, remotely controlled from console; pressure compensated, variable and reversible. Auxiliary hydraulic pump provides oil to operate all hydraulic cylinders, including elevation and steering. An optional additional pump may be installed for extended widths or special applications.
Hydraulic Oil Filtration
Three-micron absolute-filtration pre-filtered supply system. All other hydraulic circuits filtered return-side, 10 microns, nominal. Auxiliary control system pressure- side filter, 3 microns, absolute.
Water System
Hydraulically driven pump delivers 800 psi (5,512 kPa) water to hose and high-powered nozzle for cleanup and utility use. Onboard water storage capacity is 200 gal (757.07 L).
Grade Control
HYDRA-MATION® all-hydraulic control system is fully proportional. Pressure compensated, variable-displacement pump provides hydraulic oil to the direct-acting servo-valve proportional sensors. Individual flow control at sensors for fine tuning.
Elevation Control
Operator selection for automatic or manual mode. Four elevation control sensors with extendible mounting arms. Calibrated-scale adjusting hardware for sensors. Standard control system arrangement includes equipment for four-point control (dual stringline), lock-to-grade for automatic reference control of elevation.
Steering
Operator selection for automatic or manual mode, forward or reverse. Right-hand or left-hand stringline steering control mounting. Separate operator selection for manual steering in transport mode. Calibrated-scale hardware for adjusting sensor position and fine-tuning alignment. Four steering sensors standard. Remote manual steering switches located on elevation-sensor mounting arms, close to each leg.
Operator's Console
Rubber-booted all-weather switches. Locking levers protect critical function controls.
EDC-controlled hydrostatic auger drive and track drive for improved operator control.
Uni-lever controls for auger and travel.
The following functions are controlled by electrical switches from the console: Ignition, Powered Crown, Throttle, Water System, Sideforms.
Selector switches for manual or automatic control of elevation or steering.
Roll-top lockable anti-vandalism console cover
Subframe
Independent heavy-duty subframe supports spreading components and provides alternate positioning of components. Hydraulic system includes quick couplers and electrical cables equipped with cannon-type plug connectors for disassembly/reassembly.
