question Bedford CALM crane / Foden FH70 limber crane

[robin craig]

The cranes on these two vehicle look very much alike.

 

We have a Bedford Calm that is rated at 3300kg at 1.92m from the hard point at the end of the first section before the second joint.

 

This distance is just about impossible to lift anything off the ground as it is right at the edge of the vehicle.

 

There is an Foden FH70 limber on the milweb classifieds that is shown lifting an old tractor. Im sure our crane would not be able to do the same lift yet the cranes look identical.

 

Anyone able to comment?

 

There is also a picture that I have permission to use that shows this Land Rover 1 tonne on the back of a Bedford CALM after a nasty accident, I wonder how it was put on the bed? I would love to be able to do the same capacity lift.

Robin, the Foden crane has the same rating as you suggest giving a capacity of 6.3 ton metres; the 101 weighs circa 2 tons so could be lifted at a radius of 3.15m which should be enough to lift and place it on the rear of the truck.

Robin we had a three similar cranes all direct from MOD all where crap at lifting. All three we adjusted main relief valve so it blew of at 2750psi and all were good to go. The only one I checked the pressure on was wire locked and valve blew of at 1200 psi that was on a foden F70. I have found a lot of MOD hydraulic equipment has relief valves set about half way to designed working loads both EKA wreckers I have had used to cut out at 12 ton on main winch until altered
