![]() There are a couple of ways in which a MEWP (formerly known as an aerial work platforms) can be overloaded: Adding too much weight to the platform on the ground or adding weight to the platform while elevated. At this point to clear the overload condition, operators must remove weight from the platform at its current height, or they can boom down, into an allowable operating zone or to the ground to remove weight.Īdvantages of JLG’s load-sensing solution If the platform is moved into a new position, and the platform load exceeds the new rated capacity, the system recognizes and responds to this overload condition with lights, alarm and potential function interruption. The system then evaluates the platform load against the available platform capacity and determines if the machine can continue to operate.Īs the platform position changes, this signal is repeatedly compared to the rated capacity. When an operator, occupants and/or equipment is in the platform, the JLG load sensor recognizes the total platform load and sends a signal to the machine’s software system. JLG’s load sensor is located in the platform’s support structure, below and behind the operator controls, as illustrated in the images here. This saves time and effort because the unit can be recalibrated to full capacity without using or storing a load weight. The zero-calibration feature eliminates the need to use external weights to calibrate the load cell. ![]() The JLG load sending solution is a zero-load calibration system. These JLG boom lifts are designed to allow users the ability to bring more people and more materials to the job at height. HC3 stands for hi-capacity machines that allow up to three occupants across all working zones - 660 /750 /1,000-lb (299.37/340.19/453.59 kg). To meet the new load sensing requirement for example, in additional to bringing existing models up to the new standards, we expanded the allowable work envelope through the introduction of a new line of JLG® Hi-Capacity HC3 booms. ![]() It alerts an operator when the acceptable limit of the work envelope is exceeded and enables the operator to boom down or retract into a higher capacity zone to continue working. The JLG load sensing system is designed to keep the machine within the allowable work envelope by limiting range depending on platform load. Our solution is an innovative automatic load sensing system that not only enhances safety but eliminates guesswork for equipment operators. With the addition of these new requirements to the standards, boom lift manufacturers, including JLG, have looked to incorporate technologies that will help operators determine if the platform has been overloaded beyond the machine’s acceptable operating limits - without sacrificing productivity.Īt JLG, we approached compliance from the vantage point of not only meeting, but also exceeding the requirements, with productivity features that add value to both the owner and the operator. It is important to know what these alarms mean, as well as what to do to resolve an overload situation. These systems also need to include audio and visual warnings to help equipment operators remain within the capacity limits of the machine when working at height. The standards also stipulate that the load sensing system must disable machine functions if the load is above the platform load limit, within the respective work envelope. This means that every MEWP (formerly known as aerial work platforms), including boom lifts (articulating and telescopic), must include a load sensor to continuously monitor platform weight. The larger work envelope on an articulating lift provides you with access to those hard-to-reach places.To be in compliance with updated ANSI A92 and CSA B354 industry standards, load sensing systems (LSS), also known as overload systems, are now required on all MEWPs (mobile elevating work platforms) in North America. ![]() They offer exceptional outreach, high capacity, versatile performance and easy maintenance. JLG® engine powered articulating boom lifts give you the extra reach you need to work over and around obstacles on the job site.
