Overview of ShoulderMaster SM1500 and SM2100 Paving Attachment Models

The ShoulderMaster™ models are portable attachments specifically designed to rehabilitate and widen road shoulders. They have tubular steel chassis’s supported by dual full swivel wheels located at the front of the unit.

The rear of the unit is manufactured to facilitate ease of attachment to Skid Steer or Compact Track Loader which hydraulically operates and propels the unit. The ShoulderMasters’ are connected to the Skid Steer’s (or Posi-Trac or  Compact Track Loader) hydraulic system via two quick release high flow hydraulic hoses. A 12V connection is also required between the skid-steer electrical output and the ShoulderMasters

The ShoulderMaster™ SM1500 is supplied with a robust perpendicular screed plate asphaltic concrete or granular material placement.

The ShoulderMaster™ SM2100 is supplied with a modular screed which is designed to provide optimal delivery and placement of granular material at a high rate of dispersal

Construction materials (asphalt or granular material) are loaded into the main internal hopper at the front of the ShoulderMasters’ by the tipping action of the delivery truck. The rear wheels of the tipping truck make contact upon reversing with a set of horizontal rollers which are aligned with the tipping truck rear wheels. The Skid Steer or Compact Track Loader propels both the ShoulderMaster™ and tipping truck together in a forward motion and also controls the speed of the operation. The ShoulderMaster™ is also fitted with a video camera that is connected to a video monitor in the cabin of the Skid Steer (Compact Track Loader) which allows the operator to make ongoing adjustments to direction or speed of the Skid Steer.

The ShoulderMasters’ have a vertical screed adjustment from 50mm above the surface to 100mm below controlled by a hydraulic cylinder located in the main body of the unit.

The ShoulderMaster™ SM1500 has a horizontal adjustment range which allows for pavement widenings from 300mm to 1500mm which can be adjusted on the move, while the ShoulderMaster SM2100 has a horizontal adjustment range from 1000mm to 2100mm. They also have a hydraulic tilt function for grade control which allows for materials to be placed on grades from 0 degrees to +/- 5 degrees.

The ShoulderMaster™ is driven by an independent variable speed hydraulic drive system (Skid Steer Posit-Trac or Compact Track Loader) with the mechanisms being controlled on the ShoulderMaster™ by a sectional valve hydraulic operation. The valve bank is controlled via a rechargeable hand-held radio control unit (HRRCU).

The system is designed to allow for the unit to be controlled remotely outside the safety exclusion work-zone where the ‘train’ of vehicles (Skid Steer, ShoulderMaster™ and Tipping Truck) is operating. This remote control operation provides greater operator safety to reduce the risk of injury to the worker-on-foot.

The speed of construction material delivery can be varied by the remote control via the variable speed hydraulic motor to cater to varying depths and widths of the excavation that may be encountered.
