product Introduction
The 388-II backhoe loader is equipped with a 70kW Weichai National II engine, Minimum fuel rate ≤ 218g/km.hwhich provides stable power for the excavator to drive and work.The H outrigger hydraulically shifts sideways to provide solid support for the body and maintain the balance of the body; the digging arm can be slid, effectively expanding the operating range of the digging arm;Comes standard with air conditioning to provide a comfortable working environment for the driver in hot and cold weather conditions.
Q: What does it mean when it is written in this product introduction that the backhoe arm can be skidded?
A: There is a sliding frame between the two legs of the back wheel of the backhoe loader, and the whole digging arm can be slid within the range of the sliding frame, in the case of the backhoe loader is not moving in the same place, the design of the digging arm hydraulic sliding effectively expands the working range of the digging arm, and effectively improves the working efficiency.
Q: Can the air conditioner keep the driver working in severe cold weather?
A: If you are exporting to a cold area, we recommend adding diesel heating to the cab of the backhoe loader. Diesel heater and air conditioner can provide sufficient support for the driver to work in cold weather conditions.
