Advantages of TLRTC<br />

Test Bed Highlights<br />

Maximum Test Tower Base Width : 35m x 35m<br />

Maximum Test Tower Height : 95m<br />

Maximum Compression /<br />

Uplift per leg : 1000t<br />

Allowable Overturning Moment : 70,000t-m<br />

Maximum Cross Arm Speed : 70m<br />

Maximum Transverse Wire load : 100t per point<br />

Maximum Longitudinal Wire Load : 70t per point<br />

Maximum Vertical Wire Load : 60t per point<br />

Load Application System : 65 nos.<br />

(5t capacity electrically<br />

operated winches)<br />

Load Measurement System : Strain Gauge<br />

Type Load Cell<br />

Material Testing and Calibration : 100t digital UTM tower<br />

erection through tower crane<br />

Computerised central loading and monitoring Equipped to perform tests on all types of<br />

system to simulate the actual loading tower size and shape such as square,<br />

Freedom for design engineer to choose any<br />

shape of tower to achieve optimization<br />

Electrically operated winches with dual-speed<br />

rectangular base lattice towers, monopoles,<br />

tubular structures and guyed towers form<br />

33kV to 1200 kV.<br />

variable frequency drives to enable smooth The control room is the largest of its kind in the<br />

loading country and features an un-obstructive viewing<br />

Accuracy in testing is achieved through the<br />

sophisticated in-house SCADA touch-screen<br />

based software<br />

gallery that offers 360 degree view of the entire<br />

testing facility.<br />

It is the only facility in India to have a full-fledged<br />

Towers upto 1200 kV with 95m height can be tested design and fabrication infrastructure within the<br />

Towers can be tested with exceptional heavy<br />

loading (1000t per leg) and large base width (up<br />

to 35m)<br />

testing centre – this helps in fabrication of revised<br />

tower members for replacement in the least<br />

possible time.
