ACCIDENTS

ACCIDENTS

Incidents with G5 were as Follows:
26 Nov.While driving up with a load, Nick slid 20m backwards down the mountain side above Fang camp until G5 stopped suddenly on soft snow, and overturned, throwing Nick clear, and spreading the load down the mountain side. The right handlebar required straightening, and the 1oad collected up. Ray had driven the route twice the day before, and Nick had checked it for ice, but encountered some while seeking a better route.
1 Dec.The left hand track shock absorber broke off the bogie while Ray was creeping over some exposed rocks on the plateau. A bungi-cord was used to secure the loose end, and track performance was unimpaired.
13 Dec.The throttle cable jammed twice, due partly to freezing up near the carburettor and partly to fraying at the handlebar. This increased the concern about brakes, because the throttle must be blipped when starting down a steep hil1 in order to actuate the centrifugal clutch and engine braking.
13 Dec.A head sized rock jammed between the left track and rear inner sprocket wheel, causing apparent suspension collapse. The vehicle had disturbed the rock in passing so it rolled on to the track. It needed tipping to find and extract it.
