On the PlantWorx exhibition, which befell on 23-25 September on the Newark Showground within the UK, JCB launched the 6T Sitesafe ROPS web site dumper.
The EN474 laws got here into power in February 2025, requiring web site dumpers with an working machine mass between 3,500kg and 4,500kg to have a further operator safety system, to forestall the operator from being ejected from the machine within the occasion of a roll-over. The 6T Sitesafe ROPS dumper has a most machine mass of 4,500kg.
The ROPS machine joins the full-cab 6 and 9-tonne fashions in JCB’s Sitesafe web site dumper line up. The ROPS construction options giant opening gates to both facet of the machine, with heavy-duty latches. The design permits three-points of contact when climbing onto or leaving the machine. The gates additionally present further operator stability when traversing tough floor and there’s no impression to all-round visibility.
“Some producers’ designs don’t provide a lot operator safety, whereas others have giant pads that considerably prohibit visibility to the facet and rear,” says a JCB spokesperson. “Having a great view of those areas is important when driving a dumper by means of cones, poles or previous different automobiles, so we determined that our design needed to keep the distinctive all-round visibility of a traditional ROPS dumper, whereas maximising security.”
The 6T Sitesafe ROPS dumper is powered by a 55kW (74hp) JCB DieselMAX diesel engine, that has been paired with a brand new JCB SS670 4-speed synchroshuttle transmission. Driving by means of a torque converter, JCB says this new transmission delivers best-in-class gearshifting and superior off-road efficiency. The transmission boasts a forty five% shorter gear lever throw, 35% much less shifting power and as much as 80% much less gear lever play than the earlier mannequin.
With as much as 6 litres much less oil, contributing to a lowered whole price of possession, service intervals for the gearbox have been elevated to 2,000 hours. An easy accessibility filter helps to chop service downtime and the transmission contributes to elevated productiveness. The brand new gearbox will grow to be customary on all JCB 6- and 9-tonne capability web site dumpers later this yr.
“Some producers have moved to a hydrostatic transmission on bigger dumpers, however the parasitic lack of a hydrostatic system ends in lowered efficiency,” says a JCB spokesperson. “Most prospects nonetheless just like the simplicity and efficiency of a gearbox and torque converter, as that is straightforward to service and has nice efficiency on and off-road, together with up and down steep inclines and thru deep mud, the place hydrostatic transmissions could wrestle.”
The 6T Sitesafe ROPS dumper is on the market with a Swivel Tip, permitting the machine to tip to both facet, or the Sitesafe Entrance Tip skip, which affords as much as 30% higher visibility than a traditional entrance tipping mannequin, because of its decrease total skip peak. The machines have a big, gas-strut assisted engine cover, with further lockable hatches beneath the operator’s seat. All day by day checks and repair gadgets could be simply reached from floor stage for brief service occasions.
Extra EN474 modifications that got here into power in February embody a bubble inclinometer as customary, to forestall the operator exceeding the utmost secure slope, rear view mirrors and a entrance digicam. The Sitesafe dumpers additionally profit from a brand new operator’s seat with improved adjustment.
Choices embody totally compliant street lighting, LED working lights and Sitesafe 360° digicam and entrance object detection methods, that are already an choice on cabbed fashions. Manufacturing facility-fit high-visibility steps and handles will also be specified.
