Cost of Ownership
VS651 sweeper operates at the lowest cost, with a large190 litre auxiliary fuel tank giving increased on-station time. In addition, maintenance costs are significantly reduced on the Johnston gearbox and fluid coupling, as no belts or high wearing components are required. The Johnston VS651 provides the lowest emissions and running costs, both VT and VS models operate at low fuel consumption with both the chassis and auxiliary engines using a total of 5.05l/hr at low rpms. Suction sweeping requires fewer components, resulting in less wear and tear which in turn reduces maintenance costs.
Designed to last in the toughest environments, the VS651 hopper is manufactured from 4003 stainless steel, shot blasted with aluminium oxide prior to the application of a strontium bases primer followed by a hard wearing top coat. In addition, all grey parts such as the sweepgear, powerpack and sub-frame are shot blasted and electro-magnetically powder painted in a durable two part epoxy paint finish. This ensures the sweeper continues to look as good as it performs, retaining a high residual value or longer in-service life.
The VS651 is designed to fit a wide choice of chassis models to suit specific operational requirements, confident that the Johnston VS651 sweeper will provide the power and performance to complete the task. In-cab controls are ergonomically positioned to provide safe and easy operation whilst sweeping. The CANbus system monitors sweeper performance and provides daily checks. The display incorporates as standard an audible and visual raised hopper warning, fuel gauge, engine hour metre, tachometer and a water level gauge. In addition data can be downloaded via a USB stick, showing comprehensive information from fuel consumption to average sweeping times. Throttle control of the auxiliary engine is infinitely variable ensuring optimum operational and fuel efficiency with no performance compromised. With a 1500 rev Eco-mode built into the VS651, fuel conservation is increased and noise levels reduced. A full CANbus integrated door mounted control pad allows the operator to safely adjust all the sweep options. Pendant controls connected via a flexible cable allows the operator to safely tip the body and open the rear door from either side of the cab, at the same time maintaining a clear view of the tipping area. The wide-sweep brush can also be adjusted using the pendant control to extend brush life. As standard, all Johnston V Range sweepers are fitted with a body prop, which automatically engages when the hopper is raised, and has a choice of four tipping heights. The hydrostatic drive pump is accessed via a wide lightweight service ladder giving three-point of contact, which can be folded away when not in use. All critical controls - including valves, solenoids and auxiliary equipment for pneumatic, hydraulic and water systems are contained in a purpose built locker on the right hand side of the vehicle. Additionally, the VS651 is also fitted with waterproof IP67 automotive electrical connectors for enhanced reliability. VS651 models have equipment storage lockers on both sides of the hopper for storage of hydrant or Wanderhose extension tubes. The ease of access to this equipment facilitates diagnostic checks and maintenance. As standard, the VS651 sweeper features a Pressadrain water purging system so that when freezing weather conditions are anticipated, water is easily and conveniently drained from the sweeper by a simple in-cab switch. Water jets in the nozzle boxes are self-cleaning which extends the life of the components.
The V651 provides the ideal balance between performance, environmental impact and low cost of ownership, with applications to suit all types of sweeping environments, benefits that make the Johnston V651 the sweeper of choice worldwide. Two drive options (VT and VS) provide outstanding vacuum performance. For the VS651 the Johnston hydrostatic gear box drive provides the best efficiency ratios in the industry. Versatility The versatile VS powerpack with a range of 1200 rpm - 2000 rpm, can operate efficiently in municipal environments at a lower rpm, or for one pass heavy duty resurfacing operations the engine provides full power to ensure a clean path is all that is left behind.
