M434/500 Prototype Commissioning Manual

PN W453101Rev- Nov-02-1998

Test Auxiliary Head

The auxiliary head should be checked for radius accuracy as a minimum. Load testing is optional since
the attachment is only a short extension to the main boom. Check that the auxiliary head dimensions
specified in the capacity chip file either specify an effective vertical and horizontal offset

or

length and

angular offset only.

Test with the empty hook and measure the radius in at least three positions.
