Abstract

Treecare industry workers experience a higher than average percentage of back related injuries due to the nature of the work involved.  Hence, a market has evolved for tools that help mitigate these injuries. The US manufactured LogOX 3-in-1 Forestry MultiTool is one of such tools. The goal of this study is to empirically test the potential ergonomic benefits of using the LogOX Hauler and develop an Excel calculation tool to estimate the potential total cost-savings to an organization supplying the LogOX Hauler to its workforce. The results of the biomechanical experiments using the LogOX Hauler showed significant empirical data that corroborates the claimed benefits of the hauler. The results showed that while lifting the test log using the LogOX Hauler when compared to utilizing the two-handed lifting technique correctly, the lower back strain was reduced by up to 54% or by as much as 93% when compared with using improper lifting techniques. It was also shown that the bicep strain was reduced by 47% by the LogOX Hauler, when compared to using proper lifting techniques and by 76% as compared to using improper lifting. The overall findings conclude that the LogOX Hauler effectively distributes the weight of the load across the user’s body, by placing it closer to the body’s center of gravity, and at the same time effectively distributes a portion of the lifting effort from the back to the user’s quadriceps.
