There are many different vehicles involved in construction and related industries such as mining and transportation repair including items such as bulldozers, cranes, excavators and so on. Many of these vehicles can be hired (assuming you have proper endorsements to drive them) for short term, long term or alternately for a fixed period. Any piece of heavy equipment may be referred to as a “plant.”
This article is focusing on the heavy vehicles suitable for the highway such as dump trucks and dumper trucks. They tend to be used for moving sand and gravel to specific locations.
First to look into safety
Definitely the more important aspect of heavy vehicles. When a dumper truck reverses it’s more likely to hit a person, object or vehicle. Indeed, any vehicle reversing should be treated with suspicion, the “skip” tends to be the cause of most incidents. A “skip” is an open container, common to dumpers & side dumpers. This large object creates massive blind spots. Obviously, a dumper is designed to be able to back up accurately, not just for travel, but to deliver a load to exact right spot.
To assist with reversing a spotter is advised – someone who can tell you whether it’s safe to go backward.
Next there’s a problem should the dumper truck tip over. This can be avoided by keeping it under a safe load – it’s vital to know how much a dumper truck can carry. When you drive on an uneven road you will definitely encounter slopes and other areas of uneven ground. This type of environment is more likely to lead to vehicle upturning. There are special manufacturer’s guidelines which will tell the highest gradient that the truck can operate.
You should never drive when the skip has not been lowered as it will be especially likely to tip over due to a weight change, which could be even a small blast of wind. It’s not designed to be driven like this; the tip mechanism should only be operated when the truck isn’t moving.
Inexperienced drivers are less likely to follow a set of operating instructions and may cause accidents, even fatal accidents.
Some trucks have roll over protection which is used in case a vehicle overturns or rolls over – either roll cage or roll bars. The first vehicles to use this type of protection were tractors in the 1920s. It may interest you to know that these are tested to destruction, in other words they face a destructive test including working at a lower temperature. Even if a vehicle has a roll cage it is still extremely hazardous.
Types of Dump Vehicles
A high skip dumper is useful if there’s not much space. They are approximately a tonne in weight. A heavy-duty front tip dumper is similar, but they are for larger tasks.
A dump truck has the material stored in the trailer box at the rear. Various types include:
A rigid dumper truck which is both durable and fast but can operate on the open road.
An articulated dumper truck is for the harder type of terrain, but they aren’t very good with heavy terrain.
The tracked dumper truck works by flattening the ground and means you don’t have so many problems with difficult terrain.
You can purchase a mini dumper truck for garden projects and items like extensions and so on, but you may be better served by a tractor with a trailer attachment. They’re are much more user friendly than the bigger trucks.
Many children have a fascination with these types of vehicles, but it is important to teach them to be wary, they are after all, not toys.
