PICK AND CARRY OPERATIONS
Exercise extreme caution when picking
and carrying a load.
When performing pick and carry operations or
operating on sloping ground, carry loads much less
than capacity. Keep load low and uphill from crane.
Swing load only to keep the load uphill, and always
place loads on high side.
When traveling with a load, boom should be carried
in line with direction of motion.
EMERGENCY BOOM OPERATING PROCEDURES
Although improbable the boom lift cylinders hydraulic
equalizer line could fail. If this occurs, there are devices
that allow continued crane operation. All crane functions
remain operable until the hydraulic oil in the reservoir is
depleted. The most important thing is to get the boom in
a safe position so that repairs can be made. The
following procedures are recommended for getting the
boom to a safe position should the equalizer line fail.
Dont panic. Remain in cab. All functions can be
accomplished from cab.
Maintain engine at normal operating speed.
Maintain desired boom angle by pulling back on
boom control lever, as necessary. With oil leaking
from the hydraulic system, boom angle will drop if
you do not react.
While maintaining boom at this angle: activate swing;
retract boom; and operate hoist(s) as necessary until
load is safely lowered to ground.
If over-the-side, retract as much boom as possible
and then lower boom. If over-the-front, it will not be
necessary to retract boom. Remember, boom
cannot be lowered to minimum elevation over-the-
rear, as boom would hit engine hood.
EMERGENCY LOAD LOWERING PROCEDURE
In the event of a hydraulic system failure (pumps, diesel
engines, etc.), it will be necessary to lower a suspended
load, retract the boom, swing the boom over the front
and retract the outriggers in order to tow the crane to a
To return the crane to the travel mode from; elevated
and extended boom; over-the-side; with suspended load
and outriggers extended and set; proceed as follows:
A hand pump is permanently installed
behind the sheet metal, on the right
hand side of the crane, forward of the
hydraulic reservoir. Refer to the figure
titled - Hand Pump Operation, provided
for this procedure.
Install pump handle and hoses.
Remove pump handle and three (3) hoses (one
each at 12-feet, 18-feet and 38-feet long) from
Install pump handle.
