The wheeled excavators hold a significant market share in the Europe, yet they have not seen the same trend in the North American market, the reason of which is mainly the price or sticker shock.
The wheeled excavator is more expensive than the crawler excavator, while the maintenance and operating cost is vise versa because of the undercarriage expense. So the buyer shall look beyond the short sight.
The landform and actual application where the excavator operates determines which type of excavator is employed in the project. Since the wheeled undercarriage is higher than a comparable tracked machine, some excavating depth will be lost with a wheeled excavator. Also the increasing of gravity makes the crawler machine is more stable compared with the wheeled one.
However, the off-road traction is less with the wheeled excavator, and more versatility and maneuverability, which sometimes are key factors for the operators to choose their tool. Some may consider the uneven ground as a crucial part, but the stabilizer pads make it necessary to have solid ground conditions. So the level ground isn’t as important cause the stabilizer will move independently to get an even level working mode.
SANY, a world-leading excavators manufacturer, provides diggers of various tonnages, and you can count on this brand to pick up the most suitable one for your operation. An engineer from the SANY Heavy Machinery, a subsidiary of SANY Heavy Industry, concluded that"the wheeled and tracked excavators are almost equal when doing the lifting work. When you put them side by side, you can do almost the same at least digging performance."
