Geesinknorba will be showing the greenest of green vehicles at the RWM Show: it’s the first of its new flagship GPM IV range of vehicles – known as the New Vulture – to be combined with the latest hybrid lithium-ion battery technology.
This 21st century vehicle is just about to go into service with Select Environmental Services and the key benefits it offers include significant operational savings and a major reduction in emissions gases.
Geesinknorba’s UK Business Director Colm McLister said: “This particular vehicle provides all the major benefits of the New Vulture body and then adds some more with the incorporation of the hybrid technology.
“A vehicle’s payload is fundamentally important in our business and operators were very conscious of the implications of heavier Euro6 modifications, so our engineers redesigned the New Vulture with weight reduction front-of-mind.
“Like most modern RCVs, the GPM series had developed into very sophisticated vehicles with many innovations added over the years. But not all of these were needed by all operators. So we decided to take a different approach and strip the New Vulture back to basics while making sure that all the additional paraphernalia we’d removed was still available as optional modular extras.
“It’s a very customer-focused approach with operators now just ordering the elements they want and leaving off those they don’t want. And this becomes a ‘win-win’ situation for them since they only pay for the elements they need and reduce the vehicle’s weight at the same time which ultimately improves operational efficiency and lowers lifetime costs.
“As well as making things simpler, we were also able to reduce the weight of the body which is made with one-piece, high strength pressed steel sides. Of course, that was done without compromising the strength or durability of the body. And we also moved key electronic and hydraulic components closer to the elements they were serving, which further reduced weight and redistributed it away from the tailgate to improve efficiency and weight distribution.”
Further modifications to the valvetrain and hydraulic system also improved energy efficiency. The larger hopper requires fewer cycles of the compaction system which not only reduces energy consumption but also results in less wear and a longer life for components.
And in developing a New Vulture, the engineers introduced other improvements, such as better access for maintenance and an improved driver interface. The body and its integrated lifts not only meet all the required safety standards including new electromagnetic compatibility (EMC) requirements but also go much further in anticipation of tougher standards in the future.
In addition to the efficiency, cost and green credentials of the New Vulture body, the vehicle on show at the RWM also features Geesinknorba’s innovative hybrid technology.
This uses a lithium-ion battery to power the compaction and lifting operation instead of the diesel engine. The result is a major reduction in fuel consumption with resultant cost-savings and proportionately reduced emissions. It is also much quieter, using an electric motor to power these operations instead of the vehicle’s diesel engine, which itself creates new operational possibilities.
The battery can be recharged quickly between rounds by plugging it into a mains electricity supply or, if needed, by using the power take-off (PTO) facility while the vehicle is being driven.
Colm McLister said: “Having an electric motor to operate the business end of the vehicle, which uses the precise amount of energy needed is something a diesel engine will never match. In fact, at points on a collection round where the vehicle had multiple bins to empty, the diesel engine can be switched off.
“The lithium-ion battery is much smaller than the battery we previously used. Yet it is more powerful and quicker to charge than its predecessor, so much so that a fully charged battery can power the vehicle for an entire round without recharging which is very significant. Of course, the PTO facility still exists but for a typical urban round, where the vehicle spends as much as 70% of its time lifting, loading and packing, it will not normally be needed.”
In addition, the reduction in battery weight means that a separate mounting frame is no longer needed and the reduction in its size allows the body to carry significantly more refuse which, in turn, further reduces diesel consumption and emissions.
“The latest innovations make the new Hybrid vehicle more attractive than ever. As well as the operational savings generated by improved efficiency, the vehicle is an obvious choice for anyone considering working in low emissions zones – which are only going to become more widespread across the UK.
“We also offer with it the full array of different technologies used in this industry to maximise efficiency. For instance, our Tracewaste telematics system provides operators with all the information they need to make major savings in fuel consumption and maintenance costs. They can constantly monitor individual vehicles, their drivers, the routes and even entire fleets to identify opportunities for improvement.
“And our load sense technology automatically senses how much pressure the system requires for the lifting and packing operation and delivers just that with nothing wasted.
“The New Vulture comes in different body sizes and, as always, can be fitted to any manufacturer’s chassis. The smaller battery means the hybrid technology can be applied to even smaller vehicles than before including those with narrow bodies which are popular options for collections in tight city streets.
“The lithium-ion battery’s lifespan is significantly longer than that of conventional lead-acid batteries, and the reduced reliance on the PTO further reduces the strain on the diesel engine which will only help it last longer too. Both these factors make a very positive contribution to reducing both the whole-life-cost of ownership of the Hybrid vehicle as well as the environmental impact.
In addition to the New Vulture, Geesinknorba will also be showing off an N3 rear-loading vehicle being delivered to Scottish Borders Council. You can find the Geesinknorba stand in Hall 5, 5T140-W141 at the RWM Show from September 15-17.
