Benefits of using Keestrack machines

Мобільна технологія

At Keestrack we understand how important mobility is to owners and operators, and this is reflected in the design and construction of our machines. Our aim is to minimize set up times, reduce overall weight and size, and get you up and running as soon as possible.

Дистанційний моніторинг

With large fleets and multiple sites in operation it is essential that owners know the location and status of their machines in real time, 24 hours a day.

Drive systems

In 1999 Keestrack introduced a load sensing diesel/hydraulic drive system which resulted in 25% fuel savings compared to competition.

Паливна ефективність

We know our customers need exceptional power and performance, but they also want to lower their fuel costs and reduce their environmental footprint.

Економія витрат

Purchase price is only part of the total cost of ownership. Over the lifetime of your investment, operating costs can add up and ultimately reduce your competitiveness.
