FASTENERS - Numerous fasteners are used
throughout the installation process. There are
minimum specifi cations required to securely attach
the aerial lift components. Torque values are listed
on the torque chart for the various sizes and grades
of fasteners used on the
Versalift aerial lift.
Prevailing torque nuts are used in structural
applications to prevent loosening from vibration. To
be effective, 2 t hreads must protrude beyond the
locknut once tightened. Only install unused locknuts
and bolts.
Torque seal marks are used on critical fasteners.
This proce dure provides a means for quick visual
inspection of fastener condi tion. Do not use the lift
if the Torque-Seal mark between the bolt head and
mounting surface, are not in alignment. Refer to
Figure 1 for Torque-Seal mark conditions.

WELDING SPECIFICATIONS - Some mounting
configurations require welding at installation.
Welders must be AWS certified in accordance
with ANSI A92.2 requirements. A general purpose
welding rod or wire should be used.
Time Manu-
facturing Company uses AWS ER70S-6 welding
wire or a AWS E7018 welding rod [60,000 PSI
(4218 Kg/cm
2 ) yield and 25% elongation minimum].
Always posi tion the components to provide proper
access for welding. Make certain the weld size is
according to engineering specifi cations. Repair
welds must be repaired in accordance with ANSI
A92.2 requirements. Consult factory for material
specifi cations and proper welding specifi cations.
VEHICLE AND MOUNTING SPECIFICATIONS - All
proposed aerial lift installa tions must be thoroughly
reviewed. The chassis must meet or exceed the
dimensional, structural and aesthetic requirements.
Dimensional specifi cations are important. Overall
height, length, overhang, and clearances around the
turret or under the booms are specifi c concerns. The
position of the cross members of the chassis frame
may affect mounting location. Varying the location
of the aerial lift slightly may simplify the mount ing
procedure.
Before mounting the aerial lift, a weight distribution
study is required to determine if the confi g ura tion
is acceptable for the vehicle specifi ed. Front and
rear axle curb weight must be within the vehicle
manufacturer’s ratings. Minimum and recommended
vehicle specifi ca tions are given for the aerial lift.
When this information is verifi ed, the installation
can proceed.
Properly planning for an aerial lift installation will help
guarantee proper performance and reliability of the
Versalift aerial device.
