Autopave SF-2

Variable Width Slip Form Paver

A stable of high performance pavers which also includes the unique model SF-2, nicknamed the "HVW" amongst its operators.

This concrete slipform paver is infinitely variable in width from its minimum of eight feet (2400mm) through its maximum of 22ft (6710mm).

Perfect for the odd-sized set up or other custom work.

Able to change widths hydraulically, quickly saving countless man-hours as well as mechanical supplies such as numerous costly fasteners along with the logistics of mobilizing additional machine inserts.

Features

DESIGNED TO MAXIMIZE PAVING EFFICIENCY

We designed the SF-2 HVW to be the most versatile and productive paver on the market. Smarter, more efficient, more valuable – it keeps your costs low, no matter how your paving width changes. The SF-2 HVW provides the cost- effective flexibility you need.

HYDRAULICALLY ADJUSTABLE DUAL PAVING KITS

The SF-2 HVW paver features dual paving kits mounted in tandem and modular guillotine side forms fixed to a hydraulic telescoping mainframe. The paver frame expands or contracts at the flick of a switch. Telescoping at 6 to 12 in/mi. (152 to 304 mm/min), the paver expands from a minimum paving width of 8 ft. 4 in (2.54 m) to a maximum of 20 ft (6.10 m) in less than 15 minutes. This makes the SF-2 HVW ideal for paving on/off ramps, intersections, parking lots, residential streets, highway lane additions and airport sections.

Because the width is infinitely variable, it accommodates metric and English dimensioned paving equally well. Each 48 in (1,219 mm) long dual paving kit is constructed as a water storage vessel that adds 3,340 lb (1,515 kg) of weight directly over the concrete. Easily attachable curb inserts on the left or right side of the SF-2 HVW allow you to pave integral curb sections.

QUICK MOUNT VIBRATORS

Using a unique mounting system, vibrators can be added or removed in just 10 minutes, minimizing delay during width adjustment. With the capacity to accommodate as many as fifteen individually controlled hydraulic vibrators, the SF-2 HVW delivers uniform density and optimum pavement strengths.

PRECISE CONTROLS AND STABILITY FOR SMOOTH PAVING PERFORMANCE

The SF-2 HVW maintains precise control of elevation and steering through the ultra-accurate Hydra- mation® control system. This unique automated hydraulic system can be configured to operate using:

  • 4-point, dual stringline configuration
  • Single stringline with cross-slope control
  • Lock-to-grade from a prepared surface.

Swing-away sensor mounting arms and preset operator reference points aid fast set up for paving and speedy reconfiguration for transport. With its hefty 55,000 lb (24,750 kg) operating weight, the SF-2 HVW gives you better control of the concrete for superior finishing. As a result, you can consistently achieve good profile index numbers.

TIME SAVING FEATURES

The SF-2 HVW is rich in features specially designed for today’s concrete paving contractor. Hydraulic swing legs enable optimum trackline location, even in the tightest quarters. Each track also has hydraulic power steering. Together, these two features give the SF-2 HVW its "crab-steering" mode for superior maneuverability.

Form oil or cleaning fluid stores onboard in a pressure vessel. When you’re finished paving, an onboard high pressure wash-down system makes clean up fast.

The hydraulic spreader plow operates in automatic or manual mode. An oscillating float finisher can be used in either automatic or manual mode to control oscillating speed, transverse travel speed, trowel blade pitch angle and reversing functions. Both the spreader plow and float finisher are mounted on a separate telescoping subframe, eliminating the need for any additional bolt-in elements during paving width change.

OPTIONS EXTEND PAVING CAPABILITIES

The SF-2 HVW is further adaptable when you equip it with any one of our attachments. These attachments are easily mounted on to the paver frame or the hydraulic telescoping subframe in minutes. As a result, the SF-2 HVW can do the work of multiple pieces of equipment, expanding your paver capabilities and utilization without expanding your fleet. This unique versatility enables the SF-2 HVW to pay for itself in a fraction of the time required for other slipform pavers.
