JCB is to fit its innovative 2 Go hydraulic isolation system across the full range of JS crawler and wheeled excavators, plus its mini and midi compact machines. Introduced after a period of testing and evaluation with main contractor Skanska UK, the 2 Go system has subsequently been recognised by the UK’s Health & Safety Executive (HSE) for its positive contribution to site safety.
The main benefits are the availability of:
* A secondary safety system
* Prevention of machine movement from outside the cab
* Reduction in accidental operation
* Availability of a retrofitted solution
Failsafe Operation
All JCB JS excavators have a hydraulic isolator lever that is lowered when the operator is in the cab to make the hydraulic circuits live and ready for use. However with 2 Go the operator has to make a secondary acknowledgment by pushing a switch on the main control fascia. This ensures that if the servo levers are moved by accident while the operator is getting into the seat, there is no chance of the working end of the machine being operated.
Later in 2013 mini and midi excavators from the 801 range upwards will benefit from the “ Go system. In these machines, the left hand servo pod is raised for the operator to enter and exit the cab, cutting off the hydraulic system. With 2 Go, there is a second button which activates the hydraulic circuits. This prevents operators lowering the servo pod from outside the machine to make small movements, ensuring that the driver is in the seat before the excavator is used.
Retrofit Availability
A retrofit programme is available for all JS excavators built before September 2012, through the JCB dealer network.
