Chock Location - JLG Triple-L 248 Operation & Safety And Service Manual

SECTION 3 - ACCESSORIES
Inspection
In addition to the trailer inspection requirements noted in
this manual, the chocks must be inspected prior to each
loading of the scissor lift for structural discrepancies and
loose or missing fasteners. Any discrepancies discovered
during this inspection must be corrected before using the
chocks.
Loading/Unloading and Securing the Scissor
LIft
Scissor lifts must only be loaded or unloaded when the
trailer is positioned on a firm level surface that is capable
of bearing the weight of the trailer and its load. The
chocks must be properly positioned to achieve the
required tongue weight (10-15% of load) for the JLG scis-
sor lift.
TO AVOID INSTABILITY, THE SCISSOR LIFT MUST NEVER BE
ELEVATED WHEN LOADING, UNLOADING, OR POSITIONED
UPON THE TRAILER.
When loading, the trailer deck must be fully lowered onto
the ground. The scissor lift must be carefully driven for-
ward into (and against) the chocks with the chassis of the
scissor lift centered within the trailer. Once both front
wheels of the scissor lift are firmly positioned against the
chock, the front and rear of the scissor lift must be prop-
erly secured to the designated tie-down points on the
trailer deck using suitable tie-down equipment. Refer to

Figure 3-2. Before moving the trailer, ensure that the trailer
deck is fully raised and the travel latch is locked into posi-
tion.
