VARIABLE WIDTH SLIPFORM PAVERAUTOPAVE SF-2
The CMI SF-2 paver is designed to be the most versatile and productive concrete slipform paver on the market, featuring a unique dual telescoping main frame and variable width paving mold it easily adapts to changing widths from site to site for maximum cost-effectiveness and flexibility.
The SF-2 paver is the only paver in the industry which features a unique two piece hydraulically operated dual telescoping main frame and paving mold, (left and right) which can extend from 8 ft 3 in to 16 ft 5 in (2.50 m to 5.00 m) wide without the need for frame or mold inserts, making transport between multiple job sites possible in a single day.
For larger paving projects the main frame can fully expand to accomodate additional bolt in mold inserts and hydraulic vibrators to extend the paving width up to 20 ft (6.00 m) wide in under an hour, without any additional frame extensions.
While the optional modular off-set paving mold system can expand its capability even further by attaching to either side of the machine for curb and gutter, median barrier or parapet wall molds and is hydraulically adjustable for rapid form changes.
HYDRAULIC TELESCOPIC FRAME AND PAVING ELEMENT ADJUSTMENT
The unique CMI SF-2 hydraulic telescoping frame and paving mold design is particularly useful when the paver has to change paving width many times during the course of a project or on a daily basis.
To minimise the time to adjust paving widths, the SF-2 also features quick release mounts for rapid inserting or removing of the hydraulic vibrator and mount assemblies as required.
The whole operation can be carried out safely from the operators platform and ground level. No crane, lifting or jacking devices are necessary for any width change of the paver.
Varying paving widths can be achieved yet still maintaining a crown in the centre line of the slab, if required. The plow assembly and pan finisher also adjust to width changes automatically as the frame extends.
SWING AND STEER ARMS
Four parallelogram swing leg arms and hydraulic power steering with crab co-ordinated front and rear steer gift the SF-2 with superior maneuverability. The leg mounts can also be vertically relocated on the leg to accommodate different ground level conditions if necessary.
The fully adjustable sensor jacks also provide automatic grade and steer control to follow a stringline or to follow a previously laid slab or profile if preferred.
FEATURES
PROPORTIONAL SENSORS
The SF-2 maintains precise control of elevation and steering through the ultra-accurate proportional sensors control system for stability and smooth paving performance.
QUICK MOUNT VIBRATORS
Using a unique mounting system, vibrators can be easily added or removed in just 10 minutes, minimizing delay during width adjustments.
CONTROL SYSTEMS
User friendly CAN-BUS control system with plug-and-play 3D wireless capability. Monitors all electronic systems such as off stringline warning and locks hydraulic grade & steer systems.
PLOW ASSEMBLY
Hydraulically driven plow, variable speed with manual depth control, adjusts automatically with telescoping mainframe width.
REMOTE CONTROL
Repositional remote control with magnetic backing provides external operator controls of mold hydraulic side plates.
EXPANDABLE PAVING MOLD SYSTEM
The SF-2 can be further adapted by attaching the modular off-set paving mold system to either side of the machine for curb and gutter, median barrier or parapet wall molds and is hydraulically adjustable for rapid form changes. In addition, the SF-2 can also be fitted with either one or two conveyor systems to feed concrete to the off-set paving mold depending on the set up of the job site.
The high speed inclined conveyor receives concrete from the truck mixer and transfers the materials onto a cross feeder conveyor, which in turn feeds the materials left or right depending on which side the paving mold is on the paver. Both conveyors are variable speed and reversible which is particularly useful where live highways are being paved and a minimum working width is required.
