Dumper 507 is compact with a low centre of gravity. These characteristics ensure stability and safety especially on slopes.
The rubber tracks profile allows traction under types of soil conditions and gives good stability and safety especially on soils with little load bearing capacity, crumbly soil or soil located on steep slopes.
No soil type is too difficult for Dumper 507!500kg capacity and 8,7 km/h maximal speed allows fast transportation of whatever load.
With 4 forward gears and 3 reverse gears you will always get the correct gear ration to amply meet all requirements of the numerous possibilities of use.All control levers of the Dumper 507 are ergonomic and easy to use.
The levers were designed so to reduce the necessary force required to activate them; the result is practical and simple to operate controls.
The steering system of the Dumper 507 designed by Grillo allows the drive’s gradual modulation by acting on the steering levers. Dumper 507 can make very tight curves by keeping one rubber track blocked as well as with a modulated radius also a wide radius. It’s that easy!
During the first movement step, traction is taken away from one of the two steering levers and, by continuing the movement, you will progressively slowdown the rubber track by means of the brake drum. This is the secret of the Dumper 507’s extreme manoeuvrability!
The Dumper 507’s rubber tracks are supported by steel rollers mounted on bushings and grease points, these are very important features to ensure high reliability and longevity over the years.
The front steel rollers are fitted with compensation springs which turn out to be useful in case of debris infiltrating the rollers or in between the rubber track and drive crown wheel thereby avoiding any damage which may occur and always ensuring that the belts are correctly tensioned.
The rubber track’s front inclination allows you to climb over steps of other obstacles.Dumper 507 is a safe machine! It’s possible to stop quickly at all times the Dumper 507 by simply releasing the control lever. The automatic brake of the Dumper 507 will activate immediately ensuring so an immediate stop even when fully loaded and also on slopes up to 48%!
There is a large range of accessories, such as the choice between two bodies, standard or “Dumper” 230 L with automatic opening. It’s possible to use the frontal hydraulic tipping system to connect an all purpose flail, sweeper, snow blade or snow thrower.
A comfortable shock-absorbed folding platform helps the operator with quick transfers.
