Crane manufacturers are developing solutions to reduce fuel consumption and emissions, such as hydrostatic transmissions and flywheel technology
Crane fuel consumption depends on various factors, such as the type of crane, the nature and duration of operations, and the weight of the loads being lifted. For instance, an 80-ton rough terrain crane can burn 15-60 gallons of fuel per day during an 8-hour shift involving heavy lifts.
Crane manufacturers are actively seeking solutions to reduce fuel consumption and emissions. One such solution is the use of hydrostatic transmissions, which are ideal for machinery requiring continuous operation and variable speed control under demanding conditions. Hydrostatic transmissions, also known as hydrostatic power transmissions or hydrostatic drives, consist of a hydraulic pump and motor in a closed-loop system, providing variable speed control and precise power transmission. This system is widely used in industries such as construction, agriculture, and material handling, powering equipment like tractors, excavators, and forklifts. By matching the transmission to the specific system requirements, crane manufacturers can maintain optimal performance, prevent unnecessary wear, and extend equipment longevity.
Another innovative solution is the implementation of flywheel technology, which offers significant fuel and emissions reductions. Flywheels capture the braking energy generated when a container is lowered and reuse it to assist in hoisting the next one. This technology has been successfully trialed by Kier, a company committed to achieving net-zero carbon across its operations. Their trial of the PUNCH Flybrid flywheel technology on a static crane resulted in decreased fuel usage and reduced generator size while still providing sufficient power for the crane's operation. Additionally, Vycon Energy has developed a flywheel energy storage system for rubber-tired gantry (RTG) cranes, which can be retrofitted to existing cranes or included in new builds. The installation of this system on a conventional RTG crane resulted in a direct fuel savings of 8-15%, and in some cases, fuel savings increased to 32-38% when combined with a smaller genset.
By adopting these advanced technologies, crane manufacturers are taking significant steps towards reducing fuel consumption and minimizing environmental impact, contributing to a more sustainable future for the industry.
