Jacks
Four 2,000 lb tubular swivel jacks attached at each corners of trailer frame support the
PCMS unit when it is not attached to a tow vehicle. These work in combination with
four optional adjustable outriggers (stabilizer bars) to support the unit when it is not
attached to a tow vehicle.
Use of the jacks allows you to safely raise and keep the trailer wheels off the ground
while the PCMS unit is in operation on worksites or during long term storage.
WARNING
Jacks may fall causing damage or injury. Make sure that all safety
pins are secured on jacks and outriggers before leaving a site.
CAUTION
Unexpected tilting of trailer can cause injury and damage.
Always fully retract & swivel jacks and outriggers to horizontal
position before towing trailer.
Make sure that all safety pins are
secured on jacks and outriggers.
Do not attempt to raise mast or position solar panels and
signboard unless all jacks and outriggers are securely in
position. Make sure that all safety pins are secured on jacks
and outriggers.
