SETTING UP FOR OPERATION ON SNOW AND ICE
Operation on snow and ice adds an additional problem due to the slippery conditions. Normal traction is
greatly reduced. Just as you need to maintain traction to walk and drive, it is required to keep Digger
Derricks and Aerial Devices in a stable position. Rotating and moving the booms may cause the truck to jerk
and move. If the unit is not set up securely the truck can slide on ice and snow while operating. When
planning your work remember that driving in snow causes snow dust to be deposited on all surfaces. The
outriggers and outrigger pads will get snow covered and slippery. Also, as you put pressure on snow, the
snow packs down and turns to ice. The person setting the unit up for operation has the entire responsibility
for a stable position. The person on the site is the only one who can evaluate the conditions and terrain.
Proper set up requires:
• Outriggers do not slide on the outrigger pads during use.
• Outrigger pads do not slide on the ground during use.
• Set the parking brakes.
• Chock wheels as required, to prevent movement down hill. Evaluate chock location to prevent the
truck pivoting around one chock.
• Set units with one set of outriggers so all tires are on the ground.
• Evaluate the terrain to determine the most flat and level set up position.
• Set up truck so if the truck does move slightly, the result isn’t catastrophic.
• Follow Operators manual for set up instructions. Do not place outriggers on Ice as slippage may occur
regardless of solid footing.
To properly set up you may need to:
• Remove snow and ice down to bare ground to prevent sliding and to evaluate the support available.
Don’t set outriggers on a manhole cover or the edge of a slope or drop off.
• Move as far as required into the street or road so if the truck does move, the tires and outriggers will
not slide into the ditch or other hazards.
• Choose a location for the truck that gives the best stability for the work to be done.
• Come back later, to do the work, if the roads are not cleared sufficiently.
• Use traction aids under the tires and outriggers such as sand and gravel or mats.
• Operate the unit smoothly by “feathering” the controls, not jerking the levers.
OUTRIGGER / UNIT CONTROL SELECTOR
The Outrigger/unit Control Selector must be in the “OUTRIGGER” position to raise or lower the outriggers.
The lever must be in the “UNIT” position to operate the boom functions. If equipped with hydraulic tools at
the outrigger valve they will have priority over other operations. When the tools are “on” the “UNIT” and
“OUTRIGGERS” will not get hydraulic oil flow and will not operate.
BOOM INTERLOCK
If the completed unit requires outriggers for stability it will be equipped with Boom Interlock. Boom Interlock
will prevent boom operation unless the outriggers are extended. The booms will not operate if the outriggers
are not extended past a predetermined point. The operator must ensure the outriggers are set properly to
provide stability. If the booms do not operate and the Outrigger/Unit Control Selector is selected to "UNIT"
then verify the outriggers are properly extended. The operation of the boom interlock does not assure Aerial
Device stability. It only serves to remind the operator that the outriggers have not been deployed.
Do not use, connect, or disconnect the lower hydraulic tool if the booms are in or near
energized lines. Death or serious injury may result if the truck becomes energized.
