Bucket Elevator
Elevator Erection (Assembly)
Erection of the elevator must not be started until the concrete foundation and the guying anchors (if any
are needed) have been completed and developed maximum strength.
IMPORTANT:
No matter who does the installation or what method is employed, the elevator must be
plumb. If it is not, it almost certainly cannot be made to operate satisfactorily.
There are two (2) basic methods of elevator erection. In this manual only the vertical assembly or
section-by-section method is considered. InterSystems does not recommend horizontal assembly wherein
entire elevators or multiple sections thereof are assembled horizontally at ground level and then raised to
the vertical and hoisted into position. The potential for damage to the elevator structure is too great.
Vertical Assembly
This method could also be termed section-by-section assembly.
Because of
the weight of the elevator's head section, InterSystems recommends that it always be hoisted in a
separate lift and then fastened to the rest of the elevator.
1. Lift the boot onto the foundation. (See Elevator Foundation
.) BE SURE THE BOOT IS
POSITIONED CORRECTLY ON THE FOUNDATION AS SHOWN ON THE DRAWINGS.
2. While the hoisting gear is still attached to the boot to prevent its tipping, accurately plumb and level
the boot base. Use appropriate fasteners to connect the base securely in position and grout the boot
base. Allow the grout to cure before further assembly is attempted.
3. InterSystems recommends that all joints between elevator sections be weather-proofed by applying
mastic compound, especially if the elevator is to remain an outdoor structure. Mastic or caulking
compound is to be provided by the user or installer. Do not use weather stripping. Use grade 5 or
higher bolts to connect sections.
