Failure of conventional snowplows is usually caused by the strain put it its rotational parts. In the case of the vertical rotation, when the snowplow is rising or falling, the sensor automatically stops the rotation and the wire could be break due to the impact from an endless drive in the reverse direction or conversely from the winding of the wire. While in motion, snowplows are frequently over turned due to their heavy weight. Snowplows are manufactured with conventional steel plates and have heavy hydraulic cylinders which makes them heavy. This can result in the damaging of the vehicle due to the mounted snowplow and its malfunctions. In this study, a composite resin blade with a high-strength and is lightweight was developed for a snowplow. In order to ensure durability of the snowplows, a new bobbin was designed to mimic the clutch of a vehicle. This study was developed to eliminate the tension and fatigue of the wire by winding the chain instead of the wire in the newly designed bobbin.

This research analyzes bucket elevator roller chain pins by finite element (FE) analysis and static structural analysis for a lightweight pin design. The stress distribution of light weight roller chain pins under static load is analyzed for safety factors and damping effect. The results show that the stress distribution is higher on the plate than on the bush pin. In order to compare experimental and FE analysis results, a light weight design approach was used to produce a prototype base pin. Because the inner diameter of the pin was different, the impact damping effect was most appropriate when the inner diameter was 34.05 ㎜, and it is used as basic research data on the impact of the roller chain and sprocket.
