have a small footprint and cause less damage to work surfaces, and when fitted with rubber tracks, they can even work in a warehouse. With low operating noise levels, they are often used on residential job sites. Specially designed attachments, like trenchers, augers and forks, add to their versatility. By selecting the appropriate attachments, agile mini excavators cope efficiently with tasks that would otherwise be performed with great difficulty. Typical applications include digging holes, creating trenches, demolishing small structures, repairing sewer lines, landscaping and general maintenance work. Advancements in modern mini excavators include high power ratings, fuel-efficient engines with low emissions and the latest hydraulic technologies for smooth performance and precise control. Robust operator cabs are designed for enhanced comfort and low noise levels, with excellent visibility for improved safety on site. PRODUCT FOCUS Mini excavators mean lower investment and operating costs. Maintenance The HPE Africa team recommends the implementation of a strict maintenance programme to ensure minimal downtime, optimum efficiency and extended service life of each machine. These procedures include checking and changing the gear oil, greasing pins and bushings, which should be done daily, changing out the hydraulic fluid and regular cleaning out the undercarriage. Safety is critical when operating construction equipment, which is why operator training is essential. Although mini excavators are small compared to other construction equipment, they can be dangerous if not used correctly. There’s no doubt; mini excavators are likely to lower investment and operating costs, ensure quicker completion of tasks, reduce top ground damage and enable easy transportation between locations. VOLVO’S COMMITMENT TO FUTURE TECHNOLOGY Volvo Construction Equipment (Volvo CE) is delivering on its commitment of ‘Building Tomorrow’ with the unveiling of its first commercial zero-emissions electric compact excavator and wheel loader. The machines, which were the first to be shown from a new electric range of Volvo branded compact excavators and compact wheel loaders (unveiled at bauma Munich), deliver zero exhaust emissions, significantly lower noise levels, reduced energy costs, improved efficiency and less maintenance requirements, compared to their conventional counterparts. From mid-2020, Volvo CE will begin to launch its range of electric compact excavators (EC15 to EC27) and wheel loaders (L20 to L28), stopping new diesel engine-based development of these models. Electric operation To make the ECR25 and L25 electric, the combustion engines have been replaced with lithium-ion batteries. The ECR25 is fitted with lithium-ion batteries and one electric motor which powers the hydraulics in order to move the machine and the attachment. The machine’s batteries store enough electric energy to power the ECR25 for eight hours in its most common applications, such as utility work. The L25 incorporates lithium-ion batteries which allow for eight hours of operation in the machine’s regular applications, including light infrastructure work, gardening, landscaping and agriculture. The L25 also incorporates 20 JUNE 2019 www.plantonline.co.za
