Past research at UC Davis has produced various interventions to reduce musculoskeletal disorders (MSDs). These MSDs are due to the inherent risk of hand-harvesting winegrapes. Injury records of vineyard cooperators have revealed that most MSDs reported during harvest occur in the lower back. The primary risk factor contributing to this particular injury is the repetitive lifting and carrying of 50--60 lb (23--27 kg) picking containers to a central collection trailer in the vineyard. The goal of this project was to design a winegrape picking-container handling system to address this primary risk factor. This proposed design is to be presented to industry for commercial production and use.

520 $a Past research at UC Davis has produced various interventions to reduce musculoskeletal disorders (MSDs). These MSDs are due to the inherent risk of hand-harvesting winegrapes. Injury records of vineyard cooperators have revealed that most MSDs reported during harvest occur in the lower back. The primary risk factor contributing to this particular injury is the repetitive lifting and carrying of 50--60 lb (23--27 kg) picking containers to a central collection trailer in the vineyard. The goal of this project was to design a winegrape picking-container handling system to address this primary risk factor. This proposed design is to be presented to industry for commercial production and use.
520 $a In the proposed harvest system, multiple empty containers are distributed for a crew of pickers to manually fill with grapes. Once filled, these containers are mechanically lifted and dumped onto a mobile machine conveyor for fruit to be discharged to a waiting bulk trailer bin. The picking task is unchanged while the risk due to lifting and carrying of full containers is eliminated.
520 $a Utilizing experience and knowledge from past field research, a container handling system for the winegrape industry has been designed. Design parameters for the system have been based on a machine platform developed and currently used by a cooperating vineyard management company. The design has been configured such that constraints in geometry, power, and performance adapt to this mobile power unit. Design recommendations from industry cooperators have been considered to enhance system adoptability and acceptance. Tools that have been used in the configuration of this design include computer-aided drafting, stress analysis, and kinematic modeling. Parts were designed and components were specified to match the manufacturing capabilities of the potential builder. The maximum intermittent power requirement for this container handling system is 4.2 horsepower (3.1 kW). The additional cost of this system to the mobile machine platform is approximately $5 ,100USD.
