In the cab, an operator will have controls for both the movement of the excavator and the manipulation of the arm and attachments of the excavator. Pedals, levers, and joysticks are used in often complex combinations to control the excavator. In modern excavators, control and measurement will be augmented with touchscreens, displays, and other forms of feedback and input in the cab. View Excavator Cabs. The length of the boom and the stick define the reach and digging depth of an excavator.

One of the core aspects of an excavator is its ability to rotate the housing and arm — multiple times and in both directions. The functionality of this free-wheeling spinning allows an excavator operator to quickly and efficiently reposition the bucket, adjust the digging angle, and move materials from a pile in the front of the machine to a truck waiting behind it. This infinite, omnidirectional twisting is one of the key factors that make an excavator such a versatile and important machine on a construction site, but, though it might seem simple enough, it takes smart design and clever mechanics to pull off this feat. From swing motors to rotate the housing to the slewing ring that allows it to smoothly spin, a lot of well-designed parts come into play to allow the machine to rotate.

With an expert excavator operator behind the controls, the fluid, fast, and precise movements of the excavator arm can be so perfectly performed and timed one might think the operator has simply grown a new arm themselves. To take a better look at how the arm works, how it's controlled, and how each part comes together to pull off its work, read on for a short exploration of how exactly an excavator arm performs its duties. An excavator arm consists primarily of a boom , stick , and attachment. A bucket is the most common attachment. Hydraulic cylinders are connected to segments of the arm and from the cab the operator extends and contracts the cylinders. This extending and contracting pivots parts of the arm at connection points to raise and lower the arm, extend it, or curl and uncurl the attachment or bucket.

The Pilot Valve outputs a pressure signal to control the main control valve to work. The main working parts of excavators generally include standard buckets, reinforced buckets, rock buckets, etc. Its structure is directly related to the safety, work efficiency, and health of the driver. By extending and contracting the cylinder rods from the cylinder housing the operator is able to lift and lower the boom. In modern excavators, control and measurement will be augmented with touchscreens, displays, and other forms of feedback and input in the cab. The travel motor assy hydraulic motors is the actuator in the hydraulic system. View Excavator Track Groups. The function of the track link assy is to connect the track shoes and receive the power transmitted by the sprocket. Author: mike zhang. View Excavator Booms. Energy is converted into high torque output through a gear system and output through a geared shaft that engages with teeth in the slewing ring.

Excavators are heavy construction equipment primarily consisting of a boom , dipper or stick , bucket and cab on a rotating platform known as the "house" [1] - although the largest form ever, the dragline excavator , eliminated the dipper in favor of a line and winch.

Cylinders, travel motors, swing motors, and other hydraulically-powered components all derive their power from hydraulic pumps on the excavator. Excavators are commonly used in a wide-range of ground conditions and must be able to both move in low-traction locations and remain firm and balanced while stationary.
