On the PlantWorx exhibition, which occurred 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 an extra operator safety system, to stop 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 aspect 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 supply a lot operator safety, whereas others have giant pads that considerably prohibit visibility to the aspect and rear,” says a JCB spokesperson. “Having a very good view of those areas is essential when driving a dumper by way of cones, poles or previous different autos, so we determined that our design needed to preserve 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 way 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 decreased whole value 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 change into commonplace 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 decreased efficiency,” says a JCB spokesperson. “Most clients nonetheless just like the simplicity and efficiency of a gearbox and torque converter, as that is simple 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 battle.”
The 6T Sitesafe ROPS dumper is accessible with a Swivel Tip, permitting the machine to tip to both aspect, or the Sitesafe Entrance Tip skip, which presents as much as 30% higher visibility than a traditional entrance tipping mannequin, due to its decrease total skip top. 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 may be simply reached from floor stage for brief service instances.
Extra EN474 modifications that got here into power in February embody a bubble inclinometer as commonplace, to stop the operator exceeding the utmost protected slope, rear view mirrors and a entrance digital camera. 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° digital camera and entrance object detection programs, that are already an possibility on cabbed fashions. Manufacturing unit-fit high-visibility steps and handles will also be specified.
