The TELE-PRO DAVIT CRANE by OZ Lifting Products LLC® has a unique boom which is capable of
being adjusted while under load. Both the angle and extension of the boom can be changed while
the crane is under load. It is the user’s responsibility to make sure the crane will not be overloaded at
any point during the lift. Changing the angle and/or the extension of the boom may raise or lower
the crane load capacity while the lift is being performed.
The angle of the boom is adjusted by using the ratchet binder on at the rear of the crane. At no time
should the ratchet binder adjusted as to lower the crane boom below horizontal. The ratchet lever
on the ratchet binder switches the ratchet binder between raise and lower.
The extension of the boom is adjusted via a square drive on the rear of the boom. This square drive
can be operated with either the winch handle or the supplied drill drive adapter. There are stops
built into the adjustment mechanism to prevent it from being overextended in either direction. It is
recommended to slowly adjust the boom extension when nearing one of these mechanical stops.
Using excess force to attempt to get the boom to exceed its normal adjustment range can cause
the mechanism to jam. This may need disassembly to be repaired and may void the warranty.
There are load ratings etched into both sides of the telescoping section of the boom. These load
ratings are for the crane itself at various extension points. On one side of the boom are the ratings
for the horizontal position. On the other side of the boom are the ratings for the plus 45 degree
position. These etched ratings do not take into account the amount of cable on the winch drum.
Load ratings including the effects of cable on the winch drum are included on two decals, one on
each side of the crane. Make sure to use the load ratings that correspond to the boom angle being
used.
