Johnson Taylor’s XGMA XG800 series of hydraulic crawler excavators features five options ranging from operating weights of 7,8 tons to 49,5 tons with bucket capacities from 1 cubic metre to 3,2 cubic metres.
All are powered by turbocharged intercooled Isuzu engines with displacements ranging from 3,059 litres to 7,79 litres and a rated power range from 53,8 kilowatts to 184 kilowatts. These all have high-efficiency to high-torque ratios
Users have a choice of digging reach ranging from 6100 millimetres to 11120 millimetres and depth from 3200 millimetres to 7360 millimetres, making it possible within the ranges to excavate anything from pipeline trenches to piled foundations.
The units move on well-known track brands, ensuring long-life durability on the hardest working components.
For transporting, the dimensions range from 5899 millimetres x 1920 millimetres x 2630 millimetres on the smaller side to the large unit at 11170 millimetres x 3440 millimetres x 3265 millimetres.
Crawler units features better stability than wheeled units and this is best seen in the versatility and manoeuvrability of the swingspeeds and travel circuits, excavating forces.
Of concern with crawler or tracked vehicles is the availability and cost of the track components, essentially consumable items. Johnson Taylor is happy to assure its customers that replacement parts are readily available at highly-competitive prices.
