APPLICATION

  • Horizontal Chain and Rope Tensile Testing Machine is designed to test chains and ropes under tension.

PRINCIPLE OF OPERATION

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 is applied by hydrostatically lubricated piston. Main cylinder pressure is transmitted to the pressure cell housed in the control panel. The pressure transmitted to the pressure cell is directly convert pressure in to load in kN shows absolute load applied on the test specimen digitally

Rotary encoder is used to show displacement & it will display with load in electronic panel.

Machine consists of

1. STRAINING UNIT:

It consists of a hydraulic cylinder and a crosshead 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 crosshead is connected to two screwed columns and is driven by a motor for rapid adjustment of test length.

The stationary crosshead is pinned to the loading frame. It can be pinned along the bed length in steps of 500 mm. All these crossheads are on wheels to reduce the friction while in motion.

An elongation scale with a minimum of 1 mm 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, pendulum dynamometer, load indicator system and an autographic recorder.

A) Power Pack

The unit generates a maximum pressure of 200 kgf/cm2. The hydraulic pump provides continuously non-pulsating oil flow. Hence the load application is very smooth.

B) Hydraulics Controls

Hand operated wheels are used to control 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) Load Displacement Indicator System

This is microprocessor based electronic panel which shows load & displacement digitally. It transfers all data to computer software with showing real time graph on our software…

A overload trip switch is incorporated which automatically. Cuts out the pump motor when the load range in use in exceeded.

ACCURACY AND CALIBRATION

All Horizontal Chain and Rope Tensile Testing Machines are closely controlled for sensitivity accuracy and calibration during every stage of manufacture. Every Machine is than calibrated over of its chart ranges in accordance with the procedure laid down in British Standards 1610-1964 and IS: 1828- 1975.

Horizontal Chain and Rope Tensile Testing Machine comply with Grade "A" of BS : 1610-1964 and Grade 0.1 of IS: 1828-1975. An accuracy of + 1% is guaranteed from 20% of the load range selected to full load.

SPECIAL ACCESSORIES

This include load stabilizer, extra long frames, and a wide range of accessories offered on request at additional cost.

INSTALLATION
