What you should know about Dumper
What's a Dumper?
The Dumper is a vehicle for transporting large quantities of raw materials over short or medium distances.
It is the essential tool for quarry operations, but also for some earthworks.
The different types of Dumper
The dumper looks like a big truck, but there are many differences!
Indeed, unlike a conventional dump truck:
> The chassis is extremely rigid, sometimes even moulded in a single block.
> The device is heavy and robust
> The bucket is much faster, as it goes from horizontal to vertical in 10 seconds. In addition, it lifts completely vertically.
> The bucket is heated by the exhaust fumes to prevent clogging of the materials.
> The gearboxes are power shift type and fully automatic.
> The suspension is hydropneumatic
> The braking system is extremely efficient :
- The "rest" position of the brake is the braking position.
- The 40-disc multi-disc brakes are activated by default.
- The engine oil pressure removes the pressure from the brake, this means that when it is low (if there is an engine problem), the Dumper will brake by itself.
Its payload varies from 35 tons to 70 tons for a price varying respectively from 380 K€ to 550 K€.
It's a 4 x 2 (it has two-wheel drive).
> The rigid dumper is robust (approx. 30,000 hours of operation)
> The rigid dumper is very fast (70 km/h)
> The rigid dumper can carry a very large payload.
> It has only 4 wheels, a load of about 25 tons per wheel, which implies the use of robust tracks.
> It has only two drive wheels, which means there is a risk of skating on rainy days.
> The articulated dumper has an extra axle line, so it can use less solid tracks.
> Its 6 wheel drive gives it great off-road mobility.
> So we can use it more days in the year, about 100 days more than the Rigid Dumper.
> It has only 10,000 hours of use.
> It has a low speed (only 50 km/h)
> It carries a maximum of 40 tons. (1)
