LIFT LIFT BASKET AND METHOD FOR INSTALLING LIFT BASKET AND BODY FRAME

The invention relates to an elevator car as defined in the preamble of claim 1 and to a method for mounting an elevator car and the car frame as defined in claim 5.

10 In elevators designed to carry particularly heavy loads, such as freight lifts and various auxiliary lifts, load-bearing structures must be strong enough to withstand the weight of the load. Load-bearing structures in lifts include lifting ropes, lift car ke-15 hys and lift car floor. In order to be sufficiently durable, load-bearing structures usually have to be made quite heavy. This in turn means that the lift's lifting mechanism must be sufficiently powerful to be able to move the elevator car and the load. Heavy lifting machinery 20 is expensive and takes up a lot of valuable space. In addition, high-floor elevator car bases used in, for example, car lifts of garages or other similar elevators that carry bulky loads have a floor • ·: Because of the large surface area, the problem is possible overload of the lumbar • · · 25 if the spacious elevator car is incorrectly loaded. In this case, the lift brake friction is no longer sufficient and the elevator car slides downward. In EP 1657205 AI, JP 11-217168A and JP 52047245A disclose solutions that attempt to solve problems in the construction of such elevators.

• · • · · • * · • ·. ·· *. Because of the above reasons, rope lifts are not • • ** # · very inexpensive to lift heavy loads, so they do * · · *; · *! Often used are hydraulic lifts that do not require • · · 2 119241 because they are difficult to make cheaply and easily with elevators with a high lifting height. Hydraulic lifts are also generally more expensive, heavier and slower than traction sheaves. For example, in car parks that use elevator 5 to move vehicles from one floor to another, a slow elevator will reduce the capacity of the hall. In addition, hydraulic lifts are more difficult to protect than environmental ropes.

It is an object of the present invention to eliminate the aforementioned drawbacks and to provide an inexpensive and lightweight elevator and elevator car, the structures of which allow even heavy loads to be transported by cable car, thereby enabling the hydraulic elevators to reach higher speeds and lifting heights. Preferably, the object of the invention is to provide an elevator and elevator car which is well suited as a vehicle elevator, for example for parking garages or the like. It is a further object of the invention to provide a method for mounting an elevator car and a cage frame, by which the elevator car can be easily installed in an elevator shaft. According to the invention, ···. the elevator car basket is characterized by what is shown in the characterizing part of claim 1. The method according to the invention is characterized by what is stated in the characterizing part of claim 5. Similarly, other embodiments of the invention are characterized by what is stated in the invention. · · · I ”in other claims.

• · «· * ··. . Inventive embodiments are also disclosed in the description of this application. The inventive content contained in the application may also be defined otherwise than as set forth in the following claims. The inventive content may also result from several separate inventions, in particular. if the invention is considered in the light of expressions or implicit ···: subtasks or of the benefits or groups of benefits achieved * 3 119241. Thus, some of the attributes contained in the claims below may be redundant for individual inventive ideas. Similarly, the 5 different details presented in connection with each embodiment of the invention may also be used in other embodiments.

An advantage of the solution according to the invention is the lightweight yet heavy-duty structure. A further advantage is that smaller heavy lifting machinery can be used to lift 10 heavy loads, saving space and reducing costs. It is also an advantage that said heavy loads can be lifted by a cable car, whereby the lifting heights and speeds are higher than before. A further advantage is that the solution according to the invention is simple and inexpensive to implement. It also has the advantage that no single elevator structure is very large in size, which allows the elevator parts to be transported on site easily and inexpensively, and the assembly and installation of the elevator car is simple, secure and easy.

The figure shows the frame elements 22-25 at the bottom · * ·, which is dimensioned such that the seams between them coincide with the center of the floor 12 in both: Y: longitudinal and transverse directions. Floor 12 consists of four to three: 30 ice floor segments 22a-25a, as before. mentioned. The floor segments 22a-25a are prefabricated, where the sizing and fitting are done at the factory, making it easy to • • · • place the floor segments in place at the installation site. Preferably, the floor segments 22a-25a also have a factory-made rigidity layer 16 consisting of rectangular sheets of plywood or composite panels 20, for example, which is substantially the same in all floor segments, but has a stiffening layer of widths 23a, 25a 5, respectively, in the two narrower floor segments 22a, 24a, the reinforcing layer 16 is substantially equal, i.e., by a dimension W, narrower than the lower frame element 22, 24. Thus, for example, the floor segments 22a and 23a are adjacent to the floor segment 23. 16 partially overlaps the frame element 22 of the floor segment 22a, covering the seam between the frame elements 22 and 23. This solution protects the longitudinal seams of the run test elements 22-25. Each corner of the floor segments 22a-25a has anchorage points 21 to which lifting means 15 can be attached to lift the floor segment into place.
