INTEGRATED SYSTEMS 26 HYDRAULICS & PNEUMATICS November/December 2023 www.hpmag.co.uk Electrification for yard loaders and telehandlers from a single source Automation Technology, Inc. (ATI), a leading provider of customised and comprehensive valve automation solutions, has launched its zero emission electro-hydraulic actuator solution to eliminate the carbon footprint of pipeline operations. The zero emission electro-hydraulic package provides a comprehensive solution to lower emissions without requiring pipeline gas as the actuator’s primary power supply. Pipeline actuators have previously relied on using the gas from the pipeline as a power source, which is then emitted into the atmosphere. With ATI’s selfcontained zero emission electrohydraulic solution, the power source is attached to the actuator in a compact suite. Cooper Etheridge, CEO, ATI, commented: “The zero emission electrohydraulic package is the ideal solution for zero methane and VOC emission requirements for emergency shutdown valves. We are proud to help our customers achieve zero emissions within their operations.” Available in spring-return or doubleacting configurations, the zero emission electro-hydraulic package can be mounted directly to the valve via flange or custom adaption. The pump, motor, reservoir limit switches, solenoids and positioners are mounted to the actuator. In remote locations where power is not available, ATI provides solar power systems to run the systems required by the customer. ATI also provides a skid-mounted hydraulic power unit for larger operations, enabling power for multiple actuators simultaneously. Etheridge added: “ATI provides an environmentally friendly solution for customers to reduce emissions and meet industry regulations. All of our actuators are designed and fully manufactured in Houston, Texas, guaranteeing quality at every step in the process.” For further information please visit: www.atiactuators.com Electrically driven yard loaders and telehandlers have already been working successfully in agriculture and at transhipments points for some time. The drive concepts are constantly being optimised and new components are coming onto the market. HAWE’s electrification experts advise on concept development and component selection. In electrification, the entire vehicle is often not redesigned, but proven work processes are electrically driven. This means that consulting at HAWE usually starts with measurements on the existing vehicle and the definition of a reference cycle, i.e. a specific, standardised workflow. After completion of the concept, this is also used to monitor success. The first step is to separate the drive and hydraulics. The efficiency of the drive can be significantly increased by the direct electrical or electromechanical (with gearbox) version of the travel drive instead of the hydrostatic one. As a result, there is also less oil in circulation. In addition, a separate electric drive, which drives the hydraulic pump for work functions such as lifting, lowering, tilting and steering, can be reduced to minimum energy consumption or even switched off completely in pure driving mode. Further optimisation potential is opened up by the electric actuation of the brakes in the wheel transmissions and a directly electrically actuated steering. A small electro-hydraulic steering unit can also increase efficiency. These measures can also be carried out without major adjustments to the working hydraulics system. The next step is to optimise the hydraulics. The focus here is particularly on the power requirement when lifting and lowering loads. Environmentally friendly and low-noise – this is what characterises the operation of electric telehandlers and farm loaders. This means that they can also be used indoors or in areas where exhaust fumes and noise would be a problem.
