A new range of bulldozers has been introduced to the Middle East and Africa by Caterpillar. The machines are similar to those that have already gone on sale in Europe and America, but with different options for the local market.
Following the introduction of the first K-family track-type tractor D6K, Caterpillar has now launched the smaller D3K, D4K and D5K track-type tractors across the Middle East.
Replacing the well-known D3G, D4G and D5G, the newcomers have seen several updates particularly in terms of the undercarriage, as well as being compatible with the firm’s AccuGrade machine control systems.
According to the company, an improved hydrostatic control system allows the K-family tractors to be more responsive and manoeuvrable.
The hydrostatic winch offers outstanding control of the load with infinitely variable modulation of speed and pull.
These results in lower operator effort compared with the outgoing models.
The optional SystemOne undercarriage option greatly reduces maintenance time and costs. It uses a rotating bushing design, which increases life and eliminates the need for bushing turns.
