Single engine, lower emissions

Scarab can justifiably claim to be the pioneer of the truck-mounted sweeper powered from a single-engine. Operating the whole machine from the engine of the truck chassis provides many advantages, including reduced fuel consumption, decreased noise and engine pollution, less weight for a greater payload, and reduced maintenance.

Flexible, truck-mounted solutions

The Merlin 55 is just one of Scarab's expertly engineered truck-mounted road sweeping solutions. Because of its flexibility, the Merlin 55 can be fitted to a wide variety of chassis from as low as 7.5 tonnes GVW.

Hydrostatic System

The Scarab designed hydrostatic gearbox is installed in the chassis driveline and allows the sweeping components to be powered directly from the chassis engine. It also offers a range of operator benefits with its simple joystick control for forward and reverse, allowing single-pedal control which reduces fatigue and enables the driver to fully concentrate on sweeping.

Powerful & Reliable Suction Performance

A stainless steel 905.5mm roof-mounted impellor is positioned to produce a short, efficient airflow path for high suction performance and reduced power consumption. This ensures the Merlin 55 provides a powerful and consistent clean in a variety of municipal and contractor applications, making it a leader in its class.

Extensive Sweeping Capabilities

The Merlin 55 is available in both single and optional dual sweep configuration. When the suction nozzle, side brush and Widesweep functions are in operation, the Merlin 55 can sweep at a 2290mm width. However, the brushes can reach an impressive 2850mm span when simultaneously dual sweeping.

Strong, Robust Hopper

The hopper is completely manufactured from strong, corrosion and abrasion-resistant 4003 Stainless Steel, which is shot blasted before a two-pack epoxy primer is applied followed by a hard-wearing topcoat. Particulate screening via a hinged stainless-steel mesh filter swings down for ease of cleaning and access to the stainless-steel inlet cone.

Total, Intuitive Control

The intuitive CANbus controls and a colour monitor provide comprehensive feedback to both the driver and service team. The clear display indicates the sweeping configuration and vehicle condition while also highlighting warnings and service reminders. Our real-time monitoring and data logging provide valuable assistance in troubleshooting technical problems and help keep your machine running at its most efficient.
