Manufacturer and Exporter of : Chain and Rope Testing Machine, Chain and Rope Tester
Description - Chain and Rope Testing Machine CRE-TS
FIE Horizontal Chain and Rope Tensile Testing is designed to test chains and ropes under tension
Operation of the machine is by hydraulic transmission of load from the test specimen to a separately housed load indicator. The hydraulic system is ideal since it replaces transmission of load through levers and knife edges, which are prone to wear and damage due to shock on rupture of test pieces
Load applied by a hydrostatically lubricated piston. Main cylinder pressure is transmitted to the pressure transducer housed in control panel. The load transmitted to the cylinder of the pressure transducer is transferred through a digital or touch screen(optional) panel. Displacement of the pendulum actuates the rack and pinion/mechanism which operates the encoder.

Construction - Chain and Rope Testing Machine CRE-TS
1) Straining Unit :
It consists of a hydraulic cylinder and a crossed coupled to the piston rod of the hydraulic cylinder, mounted on to a robust base. The cylinder and the piston are individually lapped to eliminate friction.
The stationary crosshead is pinned to the main loading frame. It can be pinned along the bed length in steps of 500mm. All these crossheads are on wheels to reduce the friction while in motion. An encoder of 0.01mm resolution is provided to measure the elongation of the specimen.
2) Control Panel :
The control panel consists of a power pack complete with drive motor and an oil tank, control, valve pressure cell transducer.
A) Power Pack :
The unit generates a maximum pressure of 200kgf/cm^2 the hydraulic pump provides continuously non-pulsating oil flow. Hence the load application is very smooth.
B) Hydraulic Controls :
Hand operated wheels are used to control the flow to and from the hydraulic cylinder. The regulation of the oil is infinitely variable. Incorporated in the hydraulic system is a regulating valve. Which maintains a practically constant rate of crosshead movement.
C) Principal of Operation :
Operation of machine is by hydraulic transmission of load from the test specimen through pressure transducer to a separately housed load indicator
The system is ideal since it replaces transmission of load through levers and knife edges, which are prone to wear and damage due to shock on rupture of test pieces.
Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the pressure transducer housed in the control panel.
The transducer gives the signal to the electronic display unit, corresponding to the load exerted by the main ram.
Simultaneously the digital encoder fitted on the straining unit gives the mechanical displacement to the electronic display unit. Both the signals are processed by the microprocessor and load displacement is displayed on the digital readouts simultaneously.
Accuracy and calibration - Chain and Rope Testing Machine CRE-TS
All FIE Horizontal Chain and Rope Tensile Machines are closely controlled for sensitivity, accuracy and calibrating during every stage of manufacture.
Every Machine is then calibrated over of its chart ranges in accordance with the procedure laid down in IS:1828-1975.
FIE Horizontal Chain and Rope Tensile Testing Machine comply with Grade 1.0 of IS:1828-1975. An accuracy of ±1% is guaranteed from 20% of the load range selected to full load.
