LOAD & HAUL Safety fi rst
JCB is launching a proximity braking system (PBS) for its wheel loader range. T e fi rst machine to benefi t will be the 19 tonne 457. T e system works with triple antennas scanning a pre-set exclusion zone around the machine for activity, and should a person enter this area, an alarm sounds in the cab, the vehicle automatically selects neutral and the parking brake is applied. For the straying person on foot, a transponder in their safety helmet can cause a vibration to alert them to the danger. T e close call is recorded with time and date information to see if there are any ways of improving site safety.
Cat’s new 745 is a 41 tonne capacity machine with a host of new features
T e system, which was developed with FCC Environment, will be rolled out across the whole range this year. Tim Burnhope, JCB chief innovation and growth offi cer, says, “Safety on-site is of paramount importance and we are delighted to launch the new proximity braking system, which drastically reduces the risks to pedestrians.” In other safety news, JCB’s side impact protection system (SIPS), which is standard on the heavy- duty XD demolition specifi cation machines, can now be ordered as an option on all models. Meanwhile JCB is extending the use of the six-cylinder MTU 6R1000
engine to the JS300, JS330 and JS370 models. T e 7.7-litre unit is tuned to deliver 241hp in the JS300 and 281hp for the JS330 and JS370 models. T is system allows the engine to meet Tier 4 Final without having to use a diesel particulate fi lter (DPF) by relying on selective catalytic reduction (SCR). T e new engine uses two fuel fi lters instead of three, reducing service costs, and a new ultra-web nanofi bre air fi lter improves fl ow.
