(LSS-V) compensates for unintentionally excessive lever movement in vertical operations, while the Variable Stability Logic PLUS (VSL+) feature optimises lifting capacity by monitoring the position and pressure of the stabiliser legs. The Dynamic Load Chart (DLC-S) reduces setup time by simulating the load capacity before opening the stabilisers. Like the lightweight boom crane
manufacturers, Hiab is focussing on emissions reduction. By making these heavy and super heavy cranes lighter, they can be used on smaller trucks, cutting both costs and emissions. But owners can go further, by making use of the company’s updated ePTO system, Hiab aPTO 44. This is lighter than the first iteration of the system, but with increased battery capacity. It can be fitted to any crane in the company’s HiPro range. The setup consists of a battery, an electric motor, a hydraulic pump and a smart electronic control system, which is packaged on the truck chassis. The status of the ePTO 44 is visible in the CombiDrive4 remote control display or on a display mounted on the crane. The ePTO 44 is designed to be fitted onto the carrier, charging the battery with power from the engine; this allows it to work on site with the engine turned off, reducing emissions and noise. That, in turn, can allow builders merchants to start deliveries earlier, getting materials to site before everyone else starts work, without worrying about the impact of noise on neighbours. Lawsons made innovative use of
the first version of Hiab ePTO, on a compressed natural gas-powered carrier, for low emissions driving. The company has chosen the ePTO 44 for use on more recent cranes, with a diesel engine. But that still offers distinct advantages for operators, with one Lawsons

delivery driver reporting that, “From an operator’s point of view, using the crane is far less tiring. We’re not fatigued because we’re not working with the constant drone of the truck’s engine running all the time when we’re unloading. After a ten-hour shift, you really notice the noise difference. Working with the ePTO makes our environment a happier place.” Mattias Berglund, director,
global product management, special applications and digital products, Hiab comments: “The new ePTO 44 raises the standard for battery-operated crane operation. The weight has been reduced and the power has been increased to provide greater, more sustainable loader crane performance while providing a safer and more comfortable working environment.”
NEXT GENERATION TECHNO Fassi has also been focusing on adding reach, without adding weight, with three new models launched in a new generation of its Techno range. The first model, the F1450R-HXP Techno launched in late 2021. This was followed by the F1750R-HXP Techno in April
2022, and the F1750RL-HXP, launched this year. The focus on all three cranes has been on their power-to-weight ratio. Launching the first model, Fassi said that this was achieved by a series of innovations, such as the digital control system, the new display interface, the brand-new stability control, the decagonal design of the secondary arm and extension booms, and the new dynamic lift control. The cranes are controlled using
Fassi’s FX990 control unit. These give the cranes greater control of stability and allow it to work in vertical positions with higher performance. This allows the crane to work closer to where loads are being delivered. With the first crane, Fassi
introduced a decagonal boom profile – first used on its US cranes – on the secondary boom. This allows for lighter sections to be used, without sacrificing capacity. Fassi says that this offers a more than 50% improvement when working vertically. The latest model, launched this spring, is the F1750RL-HXP. This is a 132tm crane, with a maximum outreach (with jib) of 40.65m.
