The Hole less
Hydraulic system eliminates the need for either a well hole or
buried piping. The best application for the Hole less product is
most any 2-story building with less than 14' of travel from one
floor to the other. Its above-ground Hole less configuration
responds effectively to the risk of soil and groundwater
contamination, and greatly reduces environment concerns. This
package-type unit is most practical for those 2-story buildings
where handicap access is required.
This line of elevators is an economical solution for mid-rise
buildings where bedrock, groundwater or existing walls make the
drilling of a jack hole difficult. These elevators can serve up to 6
floors with maximum travel of 15000 mm. The speeds can range from
0.4 to 0.96 m/s. The preferred machine room location is at the
lowest landing adjacent to the hoist way with a minimum size of 1850
mm x 1850 mm. It is possible to locate the machine room remote from
the hoist way and in many cases the machine room size can be
altered.
This line of elevators is an economical solution for mid-rise buildings. The vertical loading on the building is minimized compared to traction elevators since the elevator is supported from below. Roped hydraulic elevators can serve up to 10 floors with a maximum travel of 25000 mm. The speeds can range from 0.4 to 0.75 m/s. The preferred machine room location is at the lowest landing adjacent to the hoist way with a minimum size of 1850 mm x 1850 mm. It is possible to locate the machine room remote from the hoist way and in many cases the machine room size can be altered.
