© Easy Guides Australia An excavator means a self-propelled crawler or wheeled machine with an upper structure capable of up to a 360º rotation, which excavates, elevates, swings and discharges material by the action of a bucket fitted to the boom or arm or telescoping boom, without moving the chassis or undercarriage during any part of the working cycle of the machine. The information in this show is for operating an excavator.
© Easy Guides Australia An example of an excavator.
© Easy Guides Australia Answer: Have the track tension adjusted. Question 5. What action should you take with tracks that are loose? 1. Add grease through the high pressure fitting until the correct track tension is reached 2. Operate the machine back and forth to equalise the pressure.
© Easy Guides Australia Answer: The leak would cause a reduction in the pressure of the hydraulic line. This could cause the quick hitch to release the bucket attachment (particularly when the engine was stopped). Question 20. What effect would a hydraulic leak in the quick hitch line have on the security of the bucket on an excavator?
© Easy Guides Australia Answer: Question 46. How do you calculate the cubic capacity of the bucket on an excavator? L X W X Ht 2 First: 2 m x.5m x.5m =.5 Then:.5 ÷ 2 = 0.25 (1/4) cubic metre can be carried. Cubic capacity of bucket = L x W x H ÷ 2 Cubic capacity is ÷ 2 because of the shape of the bucket (a rectangular prism).
