ok this is where i come in handy.
i hope you are working on a hardstand concrete yard.
and the guys are not compensating for uneven ground.
in wich case i might do the same travelling tru large potholes, but if the yard is ok then
youmight have some dangerous inexperienced guys working there!(wich is a hazard to themselves and others)
a operator should only travel forward with the bottom of the container visible to their line of sight.(i hope those guys don,t work at night)
every once in a while you will come across a super heavy container wich is not possible to lift,this is when i travel backwards with the box just of the ground
anyway travelling height varies a little depending on your own height.(you must be able to look under the container and not go over the top of anything at all)
make sure the seat is correctly adjusted to the weight of the operator.
considering how inexperienced they sound,they should also retract the slew function on the spreader when travelling with a hooked up container.
to dot the i,s and cross the t,s
approach the stacks to be loaded into with the containers at line of sight (height).and in reverse when loading out of the stacks.
stop the machine before starting to lift to the desired stack height.
and they should not argue with their superiors.
this is where inductions come in handy.
as you can remind them what the yards agreements were before they started.
how high should loaded containers be stacked?(i know you didnt ask this but now you got me going)
sometimes you will end up working on dirt and i have learned that if the ground is uneven 4 boxes high with a 35 tonne load each is going to damage the box on the ground
its better to stack boxes 3 high when they are this heavy as they will not damage/buckle the box on the ground
you may let them read this,and if they disagree, you can sack em on the spot and i,m willing to come and work for you.
i hope to be of some help
