INTEGRATED SYSTEMS 14 HYDRAULICS & PNEUMATICS September 2024 www.hpmag.co.uk While adoption of wireless remote controls is widespread in some applications, there are pockets of the offhighway industry that have not yet taken the leap. Original equipment manufacturers considering the addition of remote controls may question the benefits and worry about machine redesign implications. This article offers a guide to remote control integration, addressing common concerns as well as the basics of remote control selection. Optimising operations, comfort, and safety From cranes and concrete pump trucks to machinery used in firefighting, mining, and demolition, remote controls are common in applications where visibility or safety are challenges for operators working in the cabin. Remote controls are also increasingly common in industries such as construction, agriculture, and forestry, where moving the operator away from the machine can increase productivity. In each of these applications, remote controls are optimizing operations, increasing operator comfort, and improving safety. These are the primary reasons OEMs should consider remote controls for nontraditional applications. Remote controls enable operational optimization as they allow users to exit the cabin and operate the machine from a location that provides a better view of the task or the machine’s surroundings. The elimination of blind spots leads to greater site safety and may also allow one person to perform a task that previously required two or more people. A better view can also prevent an operator from holding their head in an uncomfortable position, reducing the risk of muscular strains. Performing work from a more natural position increases operator comfort. In addition, providing operators with the option to work while standing — especially those who typically sit for the duration of their shift — can improve health and wellbeing. Another considerable benefit of remote controls is their ability to increase operator safety. In many industries, machines operate in challenging areas: steep slopes or unstable ground; within or close to buildings lacking structural integrity; and in environments that are flammable, explosive, or have poor air quality. Remote controls allow operators to work in these areas, but from a safer position, mitigating or eliminating safety hazards. While remote controls are suitable for many applications, they may not be right for every situation. Device range varies, but typically reaches up to 500 meters (1,640 feet). For applications requiring remote operation over longer distances, teleoperations may be a better, safer choice. Autonomous operation may also Autonomy and teleoperation are big news, and with good reason. These advances in machine technology are helping overcome common industry challenges, such as job site safety and productivity. But there’s another method for delivering these same benefits, and one with much lower hurdles to entry: radio remote controls. Still at the cutting edge, these devices are becoming more technologically and ergonomically advanced. Idoia Maiz, portfolio manager, Connect and Control Solutions, Danfoss Power Solutions, explains further. Beyond the cab: Making the case for remote controls be an option. Environments requiring radio silence or areas with high interference will need a tethered backup. Overcoming remote control resistance OEMs considering the addition of remote controls often have questions or concerns. Cost is sometimes a factor, particularly for base-level machines or those destined for the rental industry. A cost-benefit analysis or voice-of-customer study can help determine if the added value remote controls provide justifies the higher machine price. Another concern may be whether the devices will work in every country the machine is exported to, but many remote controls today operate on a universal 2.4 gigahertz radio frequency. Among the more frequent concerns, however, are safety and security, operator acceptance, and machine redesign.
