Within the specific objective of the SustForest Plus Project, which aims to "Improve the quality of work of resin workers, thus generating stable and quality employment in rural areas of the Southwest European region", an electric collection wheelbarrow has been designed based on the HR5 model.

The HR5e model has been equipped with a system for emptying the resin pot using an electric motor. The implementation of the electric system instead of the two-stroke engine of the previous model shortens working times and improves ergonomics and safety. These improvements will translate into greater profitability of the resin extraction activity and will help the sustainability of the resin extraction profession.

The prototype incorporates an electric motor that acts on the front wheel to facilitate the movement of the resin collector on sloping terrain during resin collection. The adjustable configuration of the rear wheels of the wheelbarrow is intended to absorb the irregularities or imperfections of the terrain that are common in resin stands.
