Based on nominal load, car size and number of persons, the car surface is verified. For this calculation the nominal load, car depth and width are to be mentioned. If a value was changed, which is relevant for the calculation, it can be updated per mouse-click. All executed calculations are carried out according to the standards selected in the construction.
Besides the free input of the car size is it also possible to choose from already predefined standard dimensions – depending on the nominal load. An undershot or exceeded valid value will be clearly shown. If the crowded load exceeds the nominal load, dependent calculations will be executed with the crowded load. Corresponding note is displayed. After any kind of changes the shown graphic will be adapted – per mouse-click – to the actual values.
Rope reliability calculation for steel ropes, plastic covered ropes and Polyrope.
After the choice of all relevant data, first of all the weight per meter, the rope weight and the minimal breaking load will be selected from the data base. After them the rope safety as well as the rope safety factor are calculated. The choice of special ropes is also possible. In this case, a link to the certificate including certificate number is displayed. The calculation is carried out automatically according to the requirements of the certificate. The options can be also used to set the validation for TRA200.
Calculation of the driving ability and optionally the surface pressure.
After the determination of all necessary information like traction sheave diameter, rope groove form, undercut and friction values, the traction and surface pressure will be calculated per mouse-click. All intermediate results are shown as well. In the case of a special cable, this calculation will also be made according to the certificate specifications. Here we have different options. Surface pressure can also be checked against by TRA200.
Calculation of hydraulic lifting cylinders, jacking pistons and cylinder bottoms for pressure and buckling according to appropriately adjusted standard.
Module to verify the permitted radial load for a selected drive or for a free input drive.
Calculation of the axles and bearing durability.
In CompuLift the pulley data is determined depending on the driving system ( rope, rope hydraulic system, hydraulics ). It is also possible to add or remove pulleys. Additionally to a free input the user has an ample manufacturer database at his disposal, where he can choose predefined pulleys as well. Corresponding to this, the bearing and axle data can be defined and after that the available axle load can be calculated.
Calculation of the pulley carriers or general carriers for deflection and permissible bending stress.
First of all the user has the possibility to define one or more beams. After determination of bearing and force effects, the results will be displayed graphically and in tabular form.
Calculation of buffer/cylinder supports for buckling.
After definition of all desired supports and individual selection of the load case ( flexible, partially attached, flexible and fixed, fixed ) per support, all results will be calculated automatically. In this case, the user will be supported with already predefined database shapes which make the input easy.
For central, eccentric, L-frame and diagonal guided lifts, including earthquake standard EN 81-77 and / or additional load on the rails.
The calculation of guide rails is distinguishes between car rails and counterweight rails ( if available ). As guideline serve the selected standard. CompuLift makes a difference between „catching“, „driving“, „loading“ and „pipe rupture“ ( at hydraulic driving ), which can be calculated individually. The impact factor depends on the adjustments for the type of load and safety gear and is generated automatically. Here too, the choice of the guide rails occurs by means of predefined profile data. Moreover the programme gives you the possibility to define the flange bending for roller guides ( point load ) and slide guides ( line load ). It is also possible to enter an additional load (M) on the rails. In the case of „ driving „ can also been calculate additionally according the standard EN 81-77 ( earthquake ).
Selection of permitted buffers for normal buffers and service support buffers.
Based on already known system data, CompuLift finds out all load data automatically. Only the manufacturer and type are determined by the user. From this selection, the program then creates a list of all valid buffers from which the user can choose comfortably.
Review of the resulting clamping force and calculation of the rope safety for governor ropes.
Equivalent to the guide rail calculations there are distinguished similarly two groups, the car governor and the counterweight governor. Of course the user has, besides a free input, a comprehensive database at his disposal. In addition to this, CompuLift covers all tripping directions (upwards, downwards, in both directions) in this calculation. The clamping force check and the governor rope calculation is also carried out.
Simplified sketch for the shaft cross-section.
This module is a useful tool for generating a shaft sketch. Landing doors can be different from floor to floor. Same landing door types or floors are grouped. In case of a difference because, for example, in the basement a different landing door type should be built, this floor can be shifted in a seperate group. If you cannot find your desired door type, then you have to change the option „product choice“ from „from data bank“ on „free input“. Both the elevator car doors, as well as with the landing doors there is additional mass are needed to be able to provide sensible graphics. Graphic functions: Increasing or reducing, measuring, zooming.
Review of a collision between connectors and brackets.
With the railplan you can detect collisions between connectors and binders before installing the rails. Various measures and distances ( such as the length of the bottommost rail ) can be easily changed until you get a correct construction. The results can be printed.
Output of a list of parts of the calculated components and accessories.
The item list gives you an overview of already calculated components and their most important properties. Moreover you can add or change attributes as you like. Finally you can save it in a PDF-file or in a SYLK-file. A SYLK-file can be imported in Microsoft Excel.
Automatic output of all forces in the pit and shaft wall. The force diagram is a useful tool for the responsible architect. By reference to previous calculations (e.g. Buffer, guide rails ect.) the diagram gives information about critical loads on the ground and on the walls. The results can be saved in a PDF-file or in a SYLK-file (e.g. Microsoft Excel).
