Abstract
Exemplary dynamic load safety devices may include a shaft. The safety devices may include a first roller bearing mounted on the shaft. The safety devices may include a second roller bearing mounted on the shaft. The first roller bearing and the second roller bearing may be spaced apart along a length of the shaft. The safety devices may include a roller mounted on the first roller bearing and the second roller bearing The safety devices may include at least one strain gauge disposed on the shaft between the first roller bearing and the second roller bearing.
Claims20
A dynamic load safety device, comprising:
- a shaft;
- a first roller bearing mounted on the shaft;
- a second roller bearing mounted on the shaft, the first roller bearing and the second roller bearing being spaced apart along a length of the shaft;
- a roller mounted on the first roller bearing and the second roller bearing;
- and
- at least one strain gauge disposed on the shaft between the first roller bearing and the second roller bearing.
A dynamic load safety device, comprising:
- a shaft;
- one or more bearings mounted on the shaft;
- a roller mounted on the one or more bearings;
- and
- at least one strain gauge disposed on the shaft.
A method of monitoring a dynamic load, comprising:
- moving a material against a peripheral surface of a roller of a dynamic load safety device, wherein the roller is mounted on a shaft using at least one roller bearing;
- measuring a strain of the shaft as the roller rotates about the shaft;
- determining that the strain exceeds a predetermined threshold;
- and
- triggering a safety action based on determining that the strain exceeds the predetermined threshold.
