Definitions
- This invention relates to a lift cab for reduced lift shaft heads.
- many lift drives are arranged in the upper end of the lift shaft.
- a lift fitter must climb onto the cabin roof of the lift cabin to gain access to the lift drive. This is basically dangerous, and even some fitter have been injured in the past when performing such checks and maintenance between the elevator car and the shaft ceiling or even killed by crushing. Therefore, the legislation has issued strict guidelines that are to make crushing impossible.
- the object of the present invention is therefore to provide a lift cage for reduced lift shaft heads, which requires a minimum shaft height at a certain elevator car height and yet able to meet the requirements of the elevator regulation with respect to the free space against the risk of crushing.
- a lift cage for reduced lift shaft heads which remain above the lift cage cross-section free of drive elements, wherein the elevator car is characterized in that the canopy is designed to be yielding on a base of at least 0.6mx 0.5m, so it is under stress with 150N or more either collapses, folds down or lowers.
- Figure 1 A lift shaft head with the elevator car in the highest position shown, with conventional lift drive when performing maintenance on the lift motor, and marked regulatory clearance F as security against the risk of crushing;
- Figure 2 A lift shaft with the elevator car in the highest position shown, with lower lying lift motor, with marked regulatory clearance F as security against the crushing;
- FIG. 3 shows a lift shaft head with the elevator car in the highest position, wherein the elevator car passes over the laterally arranged lift motor, so that maintenance work can be carried out from the elevator car;
- FIG. 4 shows a lift shaft head with the elevator car in the highest position, wherein the elevator car passes over the laterally arranged lift motor, with opened maintenance window for the execution of
- the maintenance work must be performed necessarily from the cab roof in such a conventional arrangement of the lift motor.
- the lift mechanic stands on the cabin roof.
- a free space F of 0.5m x 0.6m x 0.8m must always be present, for example as drawn.
- the cuboid with the dimensions 0.5m x 0.6m x 0.8m may be on a different side. Even if the lift motor and all other drive elements were arranged at the bottom of the lift shaft, then this marked space would have to be present.
- the elevator cab could therefore not be driven with its canopy all the way to the end of the elevator shaft head.
- FIG. 2 shows another conventional lift construction.
- the lift motor is arranged further down, not directly above the cross section of
- Lift cabin but approximately at the height of the upper cabin edge, when the cabin is in its uppermost position as shown here.
- the lift engine still has to be maintained from the outside - it is not accessible from inside the cab.
- a free space F of 0.5mx 0.6mx 0.8m must always be present on the cabin roof, whereby this can for example be as shown.
- the cuboid 0.5mx 0.6mx 0.8m can be on another side.
- Figure 3 shows an inventive lift cabin for reduced lift shaft heads.
- the elevator car when it has arrived as shown in the uppermost position, run over the laterally arranged lift motor 1 with its upper outer edge 2 completely, so that the lift motor 1 is located laterally of the elevator car 10.
- FIG. 4 shows how the maintenance of this lift construction can be performed.
- a part 3 of the side wall of the car 10 is removed inwards into the cabin 10 and parked in front of the lower part 6 of the side wall.
- this removable side wall part 3 is placed at a certain distance in front of the lower side wall part 6. The distance is maintained by spacers 12 or by a handrail on the lower side wall part 6.
- the carrying cables 7 pass very close to the elevator car 10 because the depth of the drive devices is sought to be kept as low as possible so as not to unnecessarily give space in the elevator shaft at the expense of the cabin width.
- a regulation requires that the distance from the parapet 4, on which the lift mechanic works, all the way up at least 10cm to the parts to be serviced and checked. By placing the upper side wall part 3 at a distance, it is ensured that this distance of 10 cm to the next moving parts, namely to the carrying cables but also to the guide rails, where yes is passed by the cabin for maintenance purposes, is maintained.
- the roof 9 of the elevator car 10 as shown in Figure 3 and 4 may be made of a bare sheet metal, which is fixed from below by plug or clamp connections on the cab roof. As soon as a certain load is exceeded, the connections are released and the roof 9 falls into the elevator cabin.
- the resilient roof piece can also be attached to ropes, which are, for example, spring-loaded extendable.
- ropes which are, for example, spring-loaded extendable.
- other guides of the wire cables are conceivable, so that they run only on the cabin roof.
- the roof 9 lowers the elongation of the springs 16 downwards, at least to the extent that the required free space F is available.
- the resilient roof 9 can also be designed as a hinged roof by being hinged to a corresponding hatch in the cabin roof, and is held on the side facing away from the hinge over a predetermined breaking point.
- the roof can also be designed as a hinged door, so that two hinged on opposite sides of a hatch hinged wings form the roof. A bolt provided with a predetermined breaking point closes the door wings and holds them together until a certain load has been exceeded. Then fold the two leaves down.
- these optional different measures stands in In any case, the required clearance F available, although technically it would not be necessary. But the requirement has been met and this now allows the construction of lifts with significantly reduced lift shaft heights. In practice, with cabin interior heights of 220cm, the minimum height of the lift shaft head is 255cm.
- This 45cm difference is needed by the cab design and especially by the motor drives for the lift doors as well as by a buffer zone. With even more compact electric motors for the door drives, the shaft head height can be further reduced by a few cm to approx. 240cm.
