Autopave SF-4

Four-Track Concrete Slipform Paver

A four track 'mid-range' highway class paver that is designed for high production, multi-lane main highway projects.

Unmatched in paving performance in it's size and class, the SF-4 sets the industry standard for ride smoothness.



Features

Power Distribution System

Standard machine configuration includes six (6) axial piston-type hydrostatic pumps driven by engine-mounted (flex plate coupling) 4-place pump drive gearbox.

Pumps included: two (2) 100 cc, pressure-compensated, closed loop vibrator pumps; two (2) 100 cc, EDC-controlled plow/auger drive pumps; one (1) 100 cc, EDC-controlled track drive pump, operating through 4-way Posi-Trac® flow control valve; and one (1) open-loop pressure compensated L38 dedicated control circuit pump. Optional pumps are available for additional vibrators and added attachments.

Hydraulic Oil Filtration

The hydraulic system is protected by a 3 micron (a)1 filter between replenishing and main reservoirs. 3?2 (n)3 return filters on track drive, auger drives and vibrator circuits and by 6? (a) pressure and return filters on the AUX control system.

Grade Control

A fully proportional electronic digital control system controls the grade / level operation of the paver. Operator selection for automatic or manual mode. Four (4) grade control sensors with extendible mounting arms. Standard control system arrangement includes equipment for four-point control (dual stringline), lock-to-grade for automatic reference control of elevation, or single stringline operation with two (2) sensor operation on left or right side with a slope control sensor controlling the opposite side

Drive System

Dual-range propelling system with variable hydrostatic drives for both forward and reverse. Paving range variable up to 30 ft/min (9 m/min). Travel range variable up to 60 ft/min (18 m/min).

EDC-controlled track drive and auger drive for accurate control of hydrostatic functions.

Tracks are driven hydrostatically through deep-reduction planetary gear reducers at a 257:1 ratio. Posi-Trac® flow divider control limits track slippage. Track length 8.33 ft (2,540 mm). D-4 undercarriage components with 18 in (457.2 mm) triple-grouser street shoes. 10 in (254 mm) leg barrels with 42 in (1,088.8 mm) vertical stroke.

Water System

Hydraulically-driven pump delivers 2,500 psi high-pressure water to hose and high-powered nozzle for clean-up and utility use. Onboard water storage capacity is 200 gal (758 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 location control sensors with extendible mounting arms. Calibrated scale-adjusting hardware for each sensor. 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. Two steering sensors standard. Remote manual steering switch located conveniently at each leg for set-up and transport loading

Operator’s Console

  • Rubber-booted all-weather switches.
  • Joystick controls for plow/auger and travel/paving.
  • Synchronized sequential master pave and stop control.
  • Central keyed lock-out for electrical system.
  • Four operational stops at ground-level locations.
  • Selector switches for manual or automatic control of elevation or steering.
  • Roll-top lockable anti-vandalism console cover.
  • Entire console repositions for operation mode or recesses for transport.

Profile Pan

Profile pan end sections are equipped with hydraulic-powered overbuild adjustments to compensate for the various concrete mix designs and slumps.

Sideforms

Standard sideform group: hydraulic-powered vertical operating guillotine split sideform system. Allows independent control of front and rear side panel for “daysjoint,” 0-18 in (457 mm) vertical raise operating range with ground-level remote operating stations. Paving Dimensions

Hydraulic Vibrators & Manual Controls

Lo-density® hydraulic plumbing for reduced lines per circuit; single return circuit used for vibrator manifold reducing number of hydraulic lines. Twenty-four (24) vibrator circuits, vibrator manifold mounted to kit frame; vibrator circuits individually controlled electronically through potentiometers mounted on operator center console. Twenty (20) hydraulic internal paving vibrators suspended on parallelogram linkage, hydraulically adjustable from operator’s console.

Plow

Concrete distribution is provided by hydraulic-powered spreader plow which is adjustable in height and travel speed. Spreader plow mounting and drive frame telespcopes hydraulically with paver frame providing width adjustments to meet profile requirements without additional bolt-in sections. Speed/directional controls operated at console by use of a single joystick.
