Autoplace PS-3

Placer / Spreader

Dual-lane or single-lane concrete placer/spreader featuring a 10ft 6in wide receiving hopper and 60in (1520mm) wide folding feed conveyor capable of transfer material at up to 450fpm (13.7mpm) from either the left or right side of the placer.

Material is then spread by right and left mounted, hydraulically driven 24in (610mm) diameter augers and struck off by a sectional moldboard with powered crown capability to a standard widths of 12 to 20ft (3660 to 6100mm).

An optional extension allows spreading to 32ft (9754mm).

The tractor unit uses two 12ft (3660mm) long tracks that are driven from the centrally mounted power pack.

The four legs have a maximum elevation of 30in (762mm).

  • Dual-lane or single-lane concrete placing and spreading.
  • Right- or left-hand side delivery capability.
  • Hydrostatically driven, high- capacity rotary spreader auger.

Features

Hydraulic Power Supply
Pump-drive gearbox is engine-flywheel-mounted, with pumps flange-mounted and spline-shaft-engaged. Three each, tandem-stacked pump arrangements. One open-loop, pressure-compensated L-38 dedicated control-circuit pump.

Hydraulic Drive System
Dual-range propelling system with variable hydrostatic drives for both forward and reverse. Deep-reduction planetaries provide smooth, constant travel at low speeds. Spreading speed range variable to 50 fpm (15.23 mpm); travel speed range variable to 95 fpm (28.96 mpm).

Undercarriage
Two-track system: each track is 12-ft (3.66-m)-long with 14-in (356-mm)-wide triple-grouser street shoes, D4-sized track components. Leg elevation maximum 30 in (76.2 cm).

Steering
Operator selection for automatic or manual mode. Right-hand or left-hand stringline steering control mountings. Calibrated- scale screw-type hardware for adjusting sensor position and fine-tuning alignment. Counter-rotation of tractor possible in manual mode. One steering control sensor.

Elevation
Operator selection for automatic or manual mode. Four elevation control sensors with extendible mounting arms. Calibrated-scale screw-type adjusting hardware for sensors. Standard control-system arrangement includes equipment for four-point control (dual stringline) or lock-to-grade for automatic reference control of elevation.

Mainframe
Tubular-beam telescoping mainframe is hydraulically adjustable up to 8 ft (2.44 m), providing spreading widths from 12 ft
to 20 ft (3.66 m to 6.1 m). A 6-ft (1.83-m) bolt-in section provided as standard equipment allows a tractor spreading width of up to 26 ft (7.32 m). Optional extensions may be installed to increase spreading widths to 36 ft (10.97 m).

Water System
High-pressure system for machine washdown.
Hydraulically driven pump delivers 800-psi (5,512-kPa) water for cleanup and utility use. Onboard water storage capacity is 125 gal (473 L). Includes high-pressure hose and spray nozzle.

Subframe
Independent heavy-duty subframe supports spreading components and provides alternate positioning under tractor mainframe. Hydraulic system includes quick-disconnect couplers and electrical cables equipped with cannon-type plug connectors for fast disassembly/reassembly.

Options

  • Extensions for spreading up to 36 ft (11 m)
  • Delivery conveyor extension group
  • Telescoping rear workbridge
  • Special application vibrator system
