Autopave SF-3

Two-Track Concrete Slipform Paver

Maneuverable mid range, two track slipform paver designed for arterial and highway concrete construction.

The CMI design features a heavy duty, rigid frame structure on two powerful tracks giving the SF-3 the flexibility to fit well on many diverse projects.
  • “Mid-Range” Class slipform paver for highway, industrial and airport concrete construction.
  • Versatile, high-production two-track design provides superior paving capabilities and performance unmatched in its size and class.
  • Sets the industry standard for ride smoothness – PI or IRI.

Features

Mainframe

Fast width changes with telescoping double-sided hydraulically operated extensions and Series 6A paving kit featuring pin and wedge fasteners. Optional extensions expand paving width up to 36 ft (11 m).

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

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

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. Counter-rotation possible in manual mode. One steering sensor and circuitry to install reverse steering is standard and may be used in either forward or reverse direction.

Operator’s Console

  • Rubber-booted all-weather switches.
  • Potentiometer controls for plow/auger and travel/paving.
  • Synchronised sequential master pave and stop control with machine movement.
  • Central keyed lock-out for electrical system.
  • Four operational emergency stops at ground level locations, one on each leg.
  • 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.

Crown

Unitized design segmented 60 in (1,524 mm) profile slipform paving mold to control hydraulic powered rooftop crowning system with operator control and visual position indicator.

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 ease of starting from day joints, 0-18 in (457 mm) vertical raise operating range with ground level remote operating stations.

Hydraulic Vibrators & Manual Controls

Proportional electronic / hydraulic plumbing for reduced lines per circuit; single return circuit used for vibrator manifold reducing number of hydraulic lines. 24 vibrator circuits, vibrator manifold mounted to kit frame; vibrator circuits individually controlled electronically through potentiometers mounted on operator center console. 24 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 telescopes 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.
