You have to use a ground guide during
operations .±± And
especially when levelinG ²our crane± It'll save you a lot
of downtime³´ The guide can let you know when all
Ç
outrigµer float pads
are resting on solid, level ground, (you may have to crib under each pad to get
this solid footing¶) When you're moving the boom load from side to
side or front to rear, etc·, the float Pads take the load (weight).
If a float pad is on a stump, rock, soft
or uneven ground, it'll tilt unDer the
load. The pressure of the float pad
assembly snaps off the ball on the
hydraulic Cylinder plunger±
One thing you never do is weld the
ball back on to the hydraulic plunger.
Not you ±¸¹ not anybody!
a
Broken balL on the outrigger
assEmbly cylinder plunger is a field
maintenance reºair job.
·
It»s a good id¼a to check each float
6È
pad ever so often during operation to
be sure one of 'em hasn't changed its
good solid footing.
