Hoistway Construction (Elvoron CPL)

From Garaventapedia

Jump to: navigation, search

The walls of the hoistway can be constructed of wood, poured concrete or concrete block. The wall behind the cylinder and guide rails must be load bearing and able to withstand the loads imposed by the lift.


The cylinder and guide rails are mounted to the wall with steel brackets. These rail brackets are fastened to the load bearing wall at regular intervals.

The rail bracket spacing is determined during the design phase. The rail brackets are generally every 4’ or 8’ apart, measured vertically, depending on the load capacity, size of cab and travel height. Please see final elevator shop drawings for actual locations.


All the walls of the hoistway, especially the wall behind the rails and the entrance walls, need to be flush and plumb from floor to ceiling. This is to allow for the required running clearances.


No light is required at the top of the hoistway. A light is required in the pit (see Construction of Pit for details).

Wood Construction – Well seasoned 2” x 4” wood studs should be used, 2” x 12”’s laid flat are then fastened between the studs. The idea is to use 2 x 4’s vertically, then reinforce or cross brace the wall where we will install our rail brackets.

The hoistway dimensions indicate the clear inside finished cavity. Please ensure you allow for drywall on top of the studs.

Masonry Construction – It is not necessary to make the return portion of the walls in concrete. We suggest you make them of steel and use T-bar to support the lintels. This makes it easier to finish around the door frames after they have been placed.

Door Openings – Do not construct the return walls on either side or above the door entrances until after the doors and frames have been aligned on site.

The rails, cylinder and platform are installed, then the doors are aligned to the center of the cab.

Note:

  • One PVC sleeve, a minimum of 4" (102 mm) in diameter, will be required between the hoistway and the machinery for the hydraulic hose and electrical conduit. This is to enable the installers to make the connection between the cylinder and the pumping unit. The sleeves should enter the hoistway at either corner of the support wall.
