V14 series has an operating pressures up to 480 bar (7000 psi) and speeds up to 6.500 rpm. It is designed for both open and closed circuit transmissions with 

Nearly all of these injury sources imply axial loading as the mechanism of injury. METHODS TEST APPARATUS - Because axial loading has been implicated as the cause of common and severe foot and ankle injuries seen in real world car crashes, the Univer-sity of Virginia undertook a series of lower extremity impact tests designed to determine the Moderately severe axial loading with the cervical spine in neutral position causes vertebral body failure with central depression of the subjacent superior end plate, most often at C5. With massive axial loads, the intervertebral disk herniates through the end plate of the subjacent vertebral body and causes the body to explode from within, dispersing the fragments (burst fracture). The Role of Axial Loading in Malleolar Fractures 2000-01-0155 Though rotation is thought to be the most common mechanism of foot and ankle injury in both automobile crashes and in everyday life, axial impact loading is considered responsible for most severe lower extremity injuries. Axial loading of the lower leg during short-duration impulsive events, such as ejection seat and parachute landings, or in-vehicle landmine blasts, can cause significant lower limb injuries. To date, most of the research investigating the axial injury tolerance levels of the lower An axial load is a force administered along the lines of an axis. This is typically used to describe an injury in which there is compression of the spine from the head, such as when a person dives dorsiflexion and found 45 deg.

Type 4: Fracture through the lateral mass: Unstable. Axial load and rotation Overview. Diffuse axonal injury (DAI) is a form of traumatic brain injury. It happens when the brain rapidly shifts inside the skull as an injury is occurring. Falls from height, particularly when patients land on their heels, cause axial loading of the spine that can lead to SCI.10 Diving injuries, which cause axial loading on the head, are also at high examiner stabilizes distal radius and ulna with non-dominant hand and moves patients wrist from radial deviation to ulnar deviation, whilst applying an axial load a positive test occurs when a clunk is felt when the wrist is ulnarly deviated Occurs via FOOSH or axial load directed along thumb's metacarpal Repeat Wrist and scaphoid X-rays should be obtained 2-3 weeks after initial injury to assess for The Theory of Axial Load Explained With Diagram and Examples. A force can act on an object in various ways. One such force is axial load.

An axial load is a force administered along the lines of an axis. This is typically used to describe an injury in which there is compression of the spine from the head, such as when a person dives Axial loading injuries A burst fracture of the atlas is typically caused by an axial loading force (diving injury) to the cranium and is called a Jefferson fracture. Axial loading will result in compressive forces anteriorly and tensile forces posteriorly. This will result in flexion-type of injuries. In the lumbar spine due to the lordosis, the center of gravity is posteriorly. Flexion type of injuries will straigthen the lumbar spine and result in axial loading. Any trauma to the cervical region that results in excessive hyperextension, flexion, rotation, distraction, axial loading or lateral bending may cause transection, bruising or swelling to the cord, Diffuse axonal injury (DAI) is a form of traumatic brain injury.

Lesions were distributed into specific categories: 1) acute intervertebral disc herniation (N = 4), 2) anterior subluxation of C3 on C4 (N = 4), 3) unilateral facet dislocation (N = 6), 4) bilateral facet dislocation (N = 7), and 5) fracture of vertebral body C4 (N = 4). Axial load can lead to classic patterns of injury from the hand to the shoulder. Demonstration of competency in assessing these injuries is essential in the practice of emergency medicine. This resource describes the classic axial load injuries of the upper extremity. Nearly all of these injury sources imply axial loading as the mechanism of injury.
