Here's a few pic's of our machines going at it. I have a new operator for the skid so it gives me a little more time to stand back and just observe what is actually happening. (Supervisor ). Johnny my partner is in the Ex. We have been working the machines side by side for a long time and have a clear understanding. Now I'm spending less time in the machines (and more on the bloody phone ). I've worked big machines on sites where the task is usually repetitive and communication is normally by UHF radio. However, on the smaller machines we are all over the place in very varied conditions. The task changes every bucket. The potential for an accident is real. I have the guys talk to each other about what they are going to do and with the horn each time they approach the zone of another machine. How do you guys manage your machinery when they working side by side??.
