Various types of high-pressure equipment, including airless paint sprayers, hydraulic apparatus and grease guns, are used in industry, in farming and in the home. Injection injuries from this equipment usually involve the hand and may initially appear benign. However, these injuries must be treated quickly and aggressively to prevent significant long-term disability.

Relevance. When the hydraulic fluid is operated for several cycles, impact on performance and longevity greatly increased. So, there are ways to fix this problem. To increase efficiency of system, it necessary study working processes, systems quick-change equipment machine with a lawn k shp made as whole, attached suspension device. The complexity these processes lies in fact that they allow ex...

This paper describes the application of machine vision technology to prevention of collision accidents with heavy equipment such as hydraulic excavators and cranes. The images of the back side of heavy equipment with cameras which can take a picture with 180 degree shooting angle were captured and the worker was detected by developed color image processing algorism. A laser range finder and an ...

This paper focuses on optimal hydraulic component selection for electrohydraulic systems used in high performance servo tasks. Dynamic models of low complexity are proposed that describe the salient dynamics of basic electrohydraulic equipment. Rigid body equations of motion, the hydraulic dynamics and typical trajectory inputs are used in conjunction with optimization techniques, to yield an o...

This thesis documents my personal contribution to the development of a hydraulic-based actuation system for a solar trough collector. The goal of this project was to design the actuation system using hydraulic actuators for a four meter solar collector prototype in Pittsfield, New Hampshire. After considering several hydraulic system architectures and conducting in-depth analysis into two of th...

Real-time learning control of a hydraulic actuator is studied using a cerebellar model articulation controller (CMAC) neural network architecture. Experiments are conducted on a onedegree-of-freedom hydraulic cylinder. The main applications considered are the earth-moving equipment applications. The electrohydraulic valve used to control the flow in the hydraulic circuit is an open-centre non-p...

The longwall mining method is one of the most applied methods in extracting low-inclined to high-inclined coal seams. Selection of the most suitable extraction equipment is very important in the economical, safety, and productivity aspects of mining operations. There are a lot of parameters affecting the selection of an extraction equipment in mechanized longwall mining in steeply inclined coal...
