Horizontal Tensile Testing Machine
Description
Horizontal tensile testing machine is designed specifically for tensile testing of overhead conductors, these test frames use a horizontal test opening to accommodate long specimens and high elongation demands.
2. Features
1. Large effective bed clearance enables testing of a wide range of specimens, full length specimens; sling construction; high capacity specimens.
2. An adjustable carriage is provided supported on free moving rollers for easy placement of the carriage appropriate to the nominal test specimen length.
3. Frames, fixtures and strain measurement devices can be designed & manufactured to accommodate many types of products that require tensile tests; piston head and cylinder ends fitted with low friction seals.
4. Patent integrated load cell calibration system can calibrate load cell without removing it from machine and calibrate the whole machine instead of independent load cell.
