What solutions are available if you need to lift in special circumstances but need a mobile crane? The answer is the RT, or Rough Terrain crane, which has been developed specifically for special work areas. Let's look at when to choose these tools over conventional mobile cranes!
Often, the terrain or the size of the work site does not allow, or the duration of the work to be carried out does not require, the construction and operation of a fixed crane.
This is where mobile cranes come in. However, these generate additional options. When to choose a smaller RT crane over a conventional with mobile crane as opposed to?
Features
Conventional mobile cranes are usually equipped with several tyres (between four and ten), powered by two engines and control from two cabins.
One cab and engine for the vehicle itself, and a separate pair for the crane. They are equipped with a longer wheel and can lift heavier weights than the RT daruk. They are also heavier, but still need to be propped up frequently.
An important aspect is that suitable for road transport.
Although they are relatively manoeuvrable, due to their heavy weight and size, they require a certain amount of landscaping of the work area before use.
RT cranes, on the other hand, are always mounted on a four-wheel chassis. Compared to conventional mobile cranes, they have a wider wheelbase and a wider wheel, but have a shorter boom and can lift less weight.
Off-road capability is also enhanced by four-wheel drive and taller tyres, making RT cranes more comfortable on uneven ground.
Unlike traditional mobile cranes, are equipped with only one engine, which is responsible for driving both the boom and the wheels, and is controlled from the same cab.
Their maximum speed is low, so are not suitable for road transport, there is an extra cost to transport them to the work site before use.
When?
The question arises: when should RT cranes be used? Because it requires transport, has a lower machine height and can handle lighter loads than its conventional counterparts, it is clear that it can really shine on rough, uneven terrain.
Thanks to its lower kerb weight, all-wheel drive and large wheels can easily overcome uneven, sandy, muddy, boggy or even snowy terrain. It is no coincidence that this type of mobile crane is often used in such circumstances.
Specifically in harsh conditions performs really well. If good manoeuvrability is a concern, an RT crane may also be a good choice, as its shorter length makes it suitable for use in more congested spaces.
Both types therefore have their justification, given the lifting task and the environment, the sustainability can be taken into account when making a decision and choosing the most suitable crane type.
