Hydraulic In Ground

In Ground - Passenger

IN-GROUND CAR TYPE SUMMARY

This is the traditional elevator application that has been used for many years. The jack is located directly under the platform, in the ground. The jack is protected from the ground using a PVC liner.

ADVANTAGES

Material cost for the package is less expensive than all other car types. The package is the easiest to install and is available in low capacity as well as high capacity applications. Heavy freight cars are typically always in-ground. The pit depth and overhead dimensions are typically always standard, not requiring any extended dimensions, even though the travel can be upwards to several landings.

DISADVANTAGES

Jack is located underground and oil contamination is remotely possible. The PVC liner is providing protection between the cylinder and the actual soil.

Geographic areas which experience seismic activity will present the greatest risk of oil contamination.

The jack (single stage) must go down into the ground the same distance as the travel. Drilling a jack hole can be expensive, depending upon the ground conditions.

RAIL BRACKET FASTENING TO HOISTWAY WALLS

Hoistway wall supports for rail bracket fastening are required per the layout drawing locations. For block or masonary walls, wall inserts must be installed in the walls by OTHER than the Elevator Contractor.

Masonary block must be filled with mortar around Wall Inserts to provide a solid permanent rail bracket support.

For wood and metal stud hoistway walls, covered with sheetrock, a suitable header support (running front-to-rear on each hoistway side wall) is required at each rail bracket location as per the rail force and location shown on the job specific layout drawing.
