Students at the University of Applied Sciences in North Rhine-Westphalia analysed, optimised and validated the existing clamping system of the Estrobot's tripod.
The Estrobot was initially developed by the University of Applied Sciences in cooperation with a small to medium-sited enterprise. The Estrobot is a device which is used to speed up the spreading of granulated dry levelling compound by up to 60% and also ensures a comfortable working position. It features a tripod and flexible swivel arm with a control element. This levelling device automatically moves the blade (used to spread the screed) to the pre-adjusted height and thus levels uneven segments of the foundation.
Due to the length of the main arm and the tripod legs, it is extremely important to prevent these elements from turning against each other. The slightest offset angle can cause a major shift in the levelling and affect the evenness of the screed when spreading.
In view of this fact, the old clamping system was analysed and optimised. Based on these findings, a new tripod concept with a new clamping system was developed. It has been verified that the rigidity of the clamping device could be more than doubled.
How to operate the Estrobot is explained in detail in this video: »here
norelem in the project:
Thrust washers from norelem have been used in the tripod clamping device. These are used for an improved sliding of the spacer (located between the main arm and tripod) on the fixed sleeve which is used to centre the tripod legs.
