Abstract: A load pin configured for measuring a force, the load pin including two sensors spaced apart from each other for measuring stress or tension. An axis includes a lateral surface configured to be subjected to a load from an upside in an area of the axis between the two sensors. A slot divides the axis into a lower portion and an upper portion, the slot extending essentially in an axial direction of the axis.

Abstract: A support force measurement apparatus for determining a support force on a support element of a support structure of a movable working machine. The measurement apparatus has at least one measurement element and a support leg. The measurement element is connected to a deformation body capable of being deformed with an effect of the support force, so as to form a sensor and send a signal proportional to the support force. The support leg has the sensor and is movably connected to the support element. The support element comprises a cable connection, and the cable connection is constructed in a manner of guiding electrical energy and is used for sending the signal proportional to the support force to an analysis apparatus in a machine. The support element in the support leg and the sensor are provided with electromagnetic interfaces.

Abstract: A pressure overload protector for a sensor includes a pressure-filled channel system fillable with fluid or gas, a first overload stop seated in an open position, a first diaphragm at the unseated end of the first overload stop, a second overload stop seated in an open position, a second diaphragm at the unseated end of the second overload stop, a sensor connected to a fluid channel, and a third and fourth overload stop connected by channels to the fluid channel of the sensor and terminating at a fluid exit. The overload protector provides bidirectional over and under pressure protection to the sensor.

Abstract: A shackle assembly includes a shackle body having two shackle arms extending from a bridge portion which is fixed to the two arms and connects the two arms to each other. A shackle pin can be mounted to the shackle arms and connects the two shackle arms in the mounted state. At least one pocket is formed in at least one of the shackle arms and/or the shackle pin, in which pocket a strain sensing element is received and fixedly attached to the bottom or wall of the pocket for detecting a shackle load acting on the shackle assembly. The pocket is a hole going partially through the shackle arm or going partially through the shackle pin, and the strain sensing element is a strain gauge which is attached to the wall or bottom of the hole.
