Loadpin

A force measuring bolt is a bolt connection between force-transmitting machine elements, which, besides its function as a bolt, a simultaneous measurement of the shear forces occurring in it. This measurement is performed for example by expansion measuring strips or coils.

Load pins are also known under the following terms:

• Load Measuring Pins
• Force measurement axis
• Loadpin ( in the English language )
• Axes dynamométriques ( French -speaking )

This uses the plunger particularly in hydraulics hoists such as cranes, lifts and cable cars.

Also in the three-point linkage of tractors Electronic Linkage Control is regulated by force measuring bolt. Force measuring bolt - - About the in the direction of the force effect on the hydraulic cylinder mounted bolt the control loop between hydraulic cylinder hydraulic valve / pump monitors and determines the displacement of the hydraulic cylinder.

Mounting options

Force measuring bolt must be secured so that their orientation is fixed. The axial displacement and rotation have to be fixed. To obtain accurate results, proper fixation is a prerequisite. For this, one uses a Achshalter after DIN15058.

The Achshalternuten are mostly carried out according to DIN15058. Up to a diameter of 100 mm is recommended in this standard, in addition, per force measuring bolt to use a two axle brackets and axle brackets. A small gap between the axle bracket and Achshalternut is necessary to obtain optimum results. The column should be about 0.2 mm, so that free bending of the force measuring bolt is made possible in the opposite camp.

This installation variant is referred to as pin safety with Achshalternut and Achshalterblech. Other variants are as follows:

• Pin lock with one-sided head, castle nut and cotter pin
• Pin lock with one-sided welded head plate and locking ring
