PNEG-2116
Bucket Elevator

6. The last elevator section to be lifted into position onto the elevator is
ALWAYS
the head section.
(The hood is not assembled until belt and cup installation is complete.) Lift the head onto the top
elevator section.
DO NOT install the hood at this time. Plumb the head
section and fasten it to the elevator trunk.
7. The basic elevator structure should now be complete, securely braced and/or guyed.
8. Assemble the service platform on the elevator head. If supplied by InterSystems, a drawing will be
furnished, giving specific assembly instructions and a list of specific fasteners for each detail. Do not
weld any platform clamping brackets until all platforms and ladders are assembled and correct
installation has been verified.
9. Assemble the other service and rest platforms if any were ordered and supplied.
10. Follow these guidelines while assembling ladders:
a. A length of ladder will lead up to a platform and extend upward through the platform opening to
the level of the platform’s top rail.
b. An elevator may include a short section of trunk. In these cases, an extra 10' section of ladder
and safety cage is furnished. This ladder and cage section is to be field-modified to match the
short section of trunk exactly and compensate for any variances.
c. The total lengths of safety cage will not equal the total lengths of ladders when rest platforms are
used. The bottom edges of the hoops are spaced approximately 7' above the floor level of the
platforms.
d. The bottom of the ladder, whether at ground or grade level or at the working floor, should be
surrounded by a lockable safety cage or otherwise arranged to prohibit access to unauthorized
personnel.
11. When the installer is confident that
ALL
ladders and platforms are correctly assembled and located,
weld all platform support channels to the elevator casing (trunk). The clamp bands used to
temporarily position the support channels during installation were
NOT
meant to permanently attach
the channels to the trunk.
