VT651

Cost of Ownership 

VT651 sweeper operates at the lowest cost, with a large 190 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 VT651 provides the lowest emissions and running costs, however 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.

Durability

Designed to last in the toughest environments, the VT651 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 subframe 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.

Operational Performance

The VT651 is designed to fit a wide range of chassis models to suit specific operational requirements, confident that the Johnston VT651 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 a range of 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 VT651, fuel conservation and noise levels are enhanced. 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 auxiliary engine and 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 VT651 is also fitted with waterproof IP67 automotive electrical
connectors for enhanced reliability.

VT651 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 VT651 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.

Productivity

The VT651 provides the ideal balance between performance, environmental impact and low cost of ownership, with applications to suit a full range of sweeping environments, benefits that make the Johnston VT651 the sweeper of choice worldwide.Two drive options (VT and VS) provide outstanding vacuum performance.

For the VT Range, JCB auxiliary engines combined with the Johnston mechanical step-up gear box and fluid coupling, or the Johnston hydrostatic gear box drive for the VS model, provide the best efficiency ratios in the industry.

Water Conservation

For increased productivity, an optional water recirculation system can be installed on the V651 and V801, which can double on-station time before water refilling with the added advantage of reducing dust emissions.

Water recirculation

Not only provides extended sweeping shifts but can also save 900 litres of water per day over an 8 hour shift.

Versatility

The versatile VT Range 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.

The VT651 gives a choice of three sweeping configurations, left hand or right hand sweeping which provides a swept width up to 2400mm, and simultaneous sweeping which gives a swept width up to 3600mm.

A stainless steel water tank is integrated into the floor of the hopper body, which provides ideal weight distribution between axles and weight transfer during sweeping.

Dust Emissions

Dust and debris are collected by pneumatically operated vacuum nozzles and wide diameter 250mm nozzle trunking, maximising velocity and allowing larger debris to pass easily into the hopper.

Debris is sucked in a direct route from the vacuum nozzle into the hopper, reducing wear and tear as well as maintenance. Once debris is in the hopper, the Johnston cyclonic airflow helps separate debris, and the clean air is released to atmosphere.

Hopper

Johnston's popular VT651 has a hopper volume of 6.5m³ and water tank capacity of 1572L. The VT651 is compatible with GVW 13-18,000kg chassis.

The Johnston VT651 is robustly constructed from quality materials and designed to provide years of continuous performance and reliable service. End of life disposal is enhanced by the VT651 being almost 100% recyclable.

All Johnston V Range models are built with an angled hopper floor, enabling a total discharge angle of 53-56º (model dependent) to aid load discharge.

Environmental Impact

Manufactured in a factory accredited to IS0 14001 for sustainability, Johnston are committed to providing the most environmentally sustainable equipment on the market for collecting all types of debris and litter.

Low fuel consumption is a key attribute in reducing carbon footprint and C02 emissions. With the mechanical drive systems running at maximum efficiency, the fuel consumption of the auxiliary engine is the lowest in its class with 3.3 litres per hour at 1200rpm.

The VT Range is now fitted with auxiliary engines supplied by JCB, whose engines meet the highest standards for emissions and environmental impact.

Dust emissions are controlled to the highest standards, and PM10 atomisers suppress dust to meet EUnited PM10 Standards in Europe and in America, SCAQMD Rule 1186.

Noise Suppression

VT651 sweepers are equipped with noise suppression hoods, encapsulating the auxiliary engine and fan casing. Noise at the driver's ear is less than 75 dB(A) at maximum revs (chassis dependant), creating a safer operating environment for both the driver and pedestrians.
The fully variable engine can be set to lower revs for night sweeping which reduces the noise levels by 50%.

Additional Options 

Johnston provides a comprehensive choice of options all designed to maximise versatility and performance, only a small selection are itemised below:

Supawash - A high pressure water jet, enables the operator to clean street furniture and pavements using either a fan or pencil jet spray. The lance and hose stows away neatly when not in use. In addition, high pressure water jets on a spray bar are positioned on the front of the cab, others placed behind the nozzle boxes to provide dust suppression when sweeping.

Wanderhose - Mounted on the top of the hopper to allow the emptying of drains along the sweeping route. If Powaboom is selected controls are fitted to make the operation easier, whilst the top-mounted position provides greater access to both sides of the sweeper, and also shields the driver from oncoming traffic.

Combivac Nozzles - for faster sweeping with an additional brush at the rear of the vacuum nozzle.

Rear mounted Littasnatch - with a 5.5m long lightweight suction tube for collection of debris on pavements and areas out of reach of the sweeper brushes.

Rotatilt - controlled from inside the cab, this option allows the channel brush to tilt and sweep in cambered kerbs and gutters.

Weed Ripping Brush - a heavy duty brush with thick metal tines that effectively clears vegetation that is growing and established in gutters.
