Design and Planning Guide
Choosing the Right Model...
With so many models to choose from, it may seem difficult at first to make the best choice for a particular application. As with any guideline, this brief explanation is not intended to cover every single design application question, but rather be a guide. In some cases a standard model will not fit the application and our team of engineers will need to design a custom elevator to fit your architectural specifications.
Where To Start....
The first question to answer when selecting an elevator is "What exactly do we expect the elevator to accomplish for us?"
This can be broken down into several more specific questions, which are appropriate for all types of elevators:
How much weight must it lift?
How fast should it lift it?
How many landings will be served?
How large does the cab need to be?
Are automatic doors or gates required?
Next, we have to answer questions about the building structure that will support the elevator:
What size is the hoistway?
What is the wall construction?
How deep is the pit?
How high is the overhead?
What kind of power is available?
Is a machine room available?
Is an overhead machine space available?
How many car openings are required to suit the floor plan?
Is underground drilling a problem?
These answers will usually narrow the available choices down.
Hoistway sizes, car sizes and landing configurations are available in a wide range for each type of elevator. Custom sizes and configurations to overcome existing site limitations are also possible.
Tigerlift® -The Best Elevator for the Job...
The majority of installations are best served by a hydraulic machine in terms of both performance and price. As a general rule, a direct hydraulic is most cost effective for elevators with less than 12' of travel, and a roped hydraulic is most cost effective for elevators over 12 feet.
Traction machines should be used where site conditions make the installation of a hydraulic difficult or expensive. Drum machines should be used only where price is the primary consideration.
For LULA applications, we recommend using either X3C or X5C . The code is written in such a way that it is much easier to comply using hydraulic equipment, especially if there are restrictions in pit depth and overhead. Codes and designs are subject to change without notice. Before committing to design or construction, consult with your elevator contractor, or contact our engineering department.
