US8925405B2 - Linear-motion telescopic mechanism and robot
A linear-motion telescopic mechanism according to the present invention includes a plurality of block members ( 22 ) by which an arbitrary arm length is achieved in such a manner that the plurality of block member ( 22 ) are rigidly connected to each other so as to elongate a linear-motion telescopic joint (J 3 ). On the other hand, by separating the plurality of block members ( 22 ) one by

Excavator, Boom excavator - All industrial manufacturers
Excavators have an X-shaped chassis riding on wheels or tracks. The chassis encompasses the hydraulic motors and supports a 360-degree rotating platform called the house. The house holds the operator's cab, the engine, the counterweights and the boom attachment point. The boom is connected to the bucket by the stick (or dipper arm).

What are the reasons for the slow action of excavator
A boom body comprises a boom front member, a boom intermediate member and a boom rear member. An arm-connection bracket is jointed to the boom front member and a vehicle body-mounting bracket is jointed to the boom rear member, thereby forming a boom. With this structure, a cross section of the boom body is less prone to be deformed and therefore, the plate thickness can be reduced, the

Excavator Size Classes, Defined | CASE News
Long reach: Many excavators are available in a long reach boom configuration. This is particularly helpful in demolition and material handling applications where conventional excavators may not provide the reach. Lifting capacity: An excavator doubles as a material handler on many jobsites today and often performs the work of numerous machines.

Excavator Boom Busted - Miller Welding Discussion Forums
2. Engine power too low. The engine is also one of the power systems of the excavator. The output power of the engine is too low, and the lack of power will lead to the low output power, and then the excavator will hold the car, making the whole excavator move slowly. In addition, check whether there is black smoke in the motor.

Mitsubishi Excavators and Their Parts
Mitsubishi excavators are the heavy equipments which consist of a house i.e. the cab on a whirling platform, a bucket and a backhoe which is a boom. The cab on the rotating platform remains atop an undercarriage with wheels and tracks. All the functions and movement of the excavators are made possible by the use of a hydraulic fluid which is

Stud Welding - an overview | ScienceDirect Topics
Stud welding. Stud welding is a general term used to describe joining a metal stud or similar part to a metal work-piece. Welding can be done with many processes such as arc, resistance, friction, and percussion. Arc stud welding joins the base (end) of the stud to the work-piece by heating the stud and the work with an arc drawn between the two.
