1000kN (1MN) / 2000kN (2MN) Static Compression Only Loadframe

Model：ST-RTS(1MN/2MN)

Use：The GDS Static Loadframe is actuated from the base by a Hydraulic actuator at loads up to either 1000kN or 2000kN.

Standard：GBT 50123-2019

1000KN (1MN) / 2000KN (2MN) STATIC COMPRESSION ONLY LOADFRAME

Product Code : 1MN or 2MN

The GDS Static Loadframe is actuated from the base by a Hydraulic actuator at loads up to either 1000kN or 2000kN. To increase efficiency and to reduce whole life costs the actuator is powered by a 200cc / 64MPa GDS advanced pressure controller.

This efficiency means that the full load of the frame, 1MN, can be achieved by drawing less than 1000Watts (1 or 2 kW) from mains electricity in place of a hydraulic power pack which can draw up to 30kW. 
 

Key features Benefits to the user
To increase efficiency and to reduce whole life costs the actuator is powered by a 200cc / 64MPa GDS Advanced pressure controller: This efficiency means that the full load of the frame can be achieved by drawing less than 1000 Watts (1kW) from mains electricity in place of a hydraulic power pack which can draw up to 50kW. Control is carried out by a GDS advanced pressure controller and as such is very stable and accurate. No special requirements are needed to host or service a powerpack or to protect system users from noise generated by a powerpack.
The static frame uses low pressure compressed air on the reverse side of the actuator to raise the actuator post compression: This allows a simple manual regulator to be set with a small pressure in the upper chamber of the actuator. This innovation allows lower stress testing to be carried out more efficiently and more accurately without the cost implications of using a second pressure controller for the upper chamber of the actuator. Once the regulator is set it can then be left unattended for all tests, so long as a supply of clean, dry compressed air is available at a pressure greater than 0.5MPa (5Bar).
Ideal for creep and relaxation testing: Ideal for use where displacements are very small and loads needs to be very stable and well controlled.
Infinite Volume Controller option: For tests where continuous displacement is required to amplitudes greater than 5mm.
