Rail Static Bend Testing Machine GGW Series │ GGW-3000 Features The machines controls allow for full pc control and data acquisition of results of load and extension. Rigid 4-column load frame providing superior axial and lateral stiffness and minimum maintenance, low reaction at specimen failure. Load frame with weight up to seven tones and load capacity up to 3000kN. Top mounted actuator with unchanged height of lower platform making it is easy for operators to install specimens and test fixtures. Fully covered rail testing chamber ensure the safety for operators. Sliding roller bench facilitate operator to install the specimen into testing chamber. Chrome plated columns for easy cleaning and longest life. HUALONG GGW Series Servo-hydraulic Rail Static Bend Testing Machine is designed for testing of rails after welding, analysis is performed at the edge of the weld collar of an aluminothermy weld, in order to examine one of the failure modes that occur in this weld type under high axle load conditions. Using the GGW Rail Static Bend Testing Machine during the installation of rail allows the user to periodically test the quality of welds. EN 14587-1 Railway applications. Track. Flash butt welding of rails. Part 1. New 220 and 260 grade rails in a fixed plant. Each bend test shall be continued until the bend test values reached the specified values, in case fracture does not occur, the test shall be interrupted. To ensure that fracture occurs in the welding zone, the weld shall be notched and the bend test shall be continued until the fracture takes place. If fracture occurs remote from the weld the fracture surfaces shall be inspected. The details of any weld defects shall the recorded in accordance with rail profile grip (Figure). Lack of bond shall not be permitted, Flat sport shall not be considered to be lack of bond. If fracture occurs remote from the weld the fracture surfaces shall be checked for the presence of die burn, which if detected shall cause the process to fail approval,. If fracture occurs within the rail for reasons other than die burn then another test weld specimen shall be substituted for testing.

Mechanical High Stiffness Load Frame Testing Chamber Windows On Testing Chamber Top mounted oil cylinder. High precision displacement sensor used. Actuator anti-rotation design. High precision load cell used. High stiffness testing Chamber. High precision displacement sensor is used to measure both displacement as well as bending deflection of rail. Sliding rollers facilitate specimen installation and removal. Center window is used to check the alignment of welding joint with bending tip. Dual handle to raise the sliding rollers while the installation of rail specimen and lay down the sliding...
