The Configurations of the Used Excavators

Tags: Used Sumitomo Excavators for sale used excavator in europe2013-12-18

Excavators have different sizes. The smaller ones are small size or compact excavators. Generally, the mini-excavator weighs two thousand and sixty pounds and has 13 high performances. There are 3 hydraulic pumps in excavators. two main pumps to provide oil for the arms, rotary motor, electric motors, and fittings at high pressure, while the third one is for navigation Control at a lower pressure, forming a circuit for the control of the short pipe. A used excavator mainly consists of two parts: the undercarriage and the body. The undercarriage consists of the blades, wheel frame and main reducer, and each track uses a hydraulic motor to control. In addition, the body of the used excavators includes the running room, engine and hydraulic oil boxes. The body links to the undercarriage with a center axle. There is a hydraulic swing ring in the center of the axle which makes sure the 360° movement of the excavators without hinders, delivering oil to the hydraulic motors.

What linked to the end of the suspender is the dipper arm. And the length of this dipper arm depends on the requirements of the long stick as well as the short stick. Generally, there is a bucket on the one side of the dipper arm. The bucket has a large capacity and straight cutting blade to eliminate and measure whether there is a good place to dig. As for hard rock that is hard to excavate, the bucket with GP is needed. It has small size, strong power as well as sharpen cutting blade. Buckets have different shapes and sizes for different applications. There are also many other fittings that are designed to attach to the excavator for drilling, crushing, breaking, etc.

In the earlier times, there was a long or used balance on all used Sumitomo excavators to control the back of the excavators to provide more excavator power and lifting capacity, which is a shortcoming in the middle of excavating in limited areas. Later, the first Zero Tail rotary excavator was developed, which lets balance keep into the track during rotary movement. Thus, make sure safer and more comfortable working when placed in a limited area. And this is the excavator type that commonly utilized in modern society.

It is general that each used excavator has two kinds of control configurations to control the suspender as well as the bucket. And they expand four controls from two control sticks as time goes by. And the control sticks are designed x-y to make sure the operators are able to handle fours sticks at the same time. At present, there are two kinds--SAE and ISO of control configurations . The former is common in America, while the latter is popular in rest parts of the world. When carrying out digging, the operators are permitted to choose the control configuration they prefer.
