OPERATION MACHINE OPERATIONS AND CONTROLS Shovel Work reverse direction. 3 - 109 RECOMMENDED APP In addition to the following, it is possible to further increase the range of applications by usin g various attachments Backhoe Work A backhoe is suitable for e xcavating areas that are lower t han the machine. When the condition of the machine is as shown in the diagram on the right (angle between [bucket cylinder and link] and [arm ), the maximum excavation force is force of each cylinder. is angle effectively to optimize your with the arm is from a 45° angle away angle towards the machine.
d [ arm cylinder and arm] is 90° orce is obtained from the pushing When excavating, use th working efficiency. The range for excavating from the machine to a 30° There may be some diffe rences depending on the excavation depth, but try to stay within the above range rather than o perating the cylinder to the end of it s stroke. han the machine. Shovel work is p erformed by attaching the buck et in the Ditching Work Ditching work can be perfo rmed efficiently by attaching a bucket which matches the digging operation and then setting the tracks ch to be excavated. , first dig both sides and then finally parallel to the line of the dit To excavate a wide ditch remove the center portion.
