EASY PATENT # 345966 CRANK-UP LIFTER SYSTEM
Jayco+s unique raising system has been thoroughly tested and
proven to be one of the best on the market and is relatively simple
in opcrarion. The system is operated by a manual winch. As the
\\.inch Lurt~s, the main cable, which is connected to the four
secondary cables from each corner, is shortened.
As the main
cable shortens. it pulls the secondary cables, forcing the flexible
stcci core to be pushed up~vard against the last tier of each
tclcscopic arm. Because strong force can be achieved with Iittle
cft'orr through a pulley system, the roof can be lifted easily.
CAUTION:
Never attempt to crank roof up with boat or
any item on roof.
