A versatile construction hoist system comprises a hoist trolley (2) having a first pair (16, 18) of connection members, and a work platform (32) having a second pair (38, 40) of connection members. The work platform is releasably connectable to the trolley through interconnection of the first and second pairs of connection members with the work platform in a horizontal position in which the work platform floor is situated at the first level (55) relative the trolley. A transport platform (60), which has a third pair (74, 76) of connection members, is releasably connectable to the trolley (2) through interconnection of the first (16, 18) and third pairs (74, 76) of connection members with the transport platform in a horizontal position in which its floor (62) is situated at a second level (80) relative the trolley, said second level being below said first level. An adapter (66) enables use of standard transport platform elements.

The invention concerns an arrangement for sliding doors of the type where a door leaf (3) comprises a number (n) of interlinked and jointed sections (4:1 - 4:n) in which adjoining sections are able to rotate around a joint axis (A) from a position in which the sections are in alignment with each other to a relative angled position, whereby the door leaf can slide in the door opening (6) in guides (8, 9), each of which comprising a first and a second interacting guide element (8', 8"; 9', 9") arranged on two opposing end edges (22, 23) of the door leaf and the corresponding sides of the door opening. To obtain a sound insulating door, there is an elastically deformable material between the adjoining and relatively flexible sections (4:1-4:n) to separate the sections from each other.

A passenger hoist or lift, in particular a temporarily erected building hoist, comprises a hoist cage (1) having a control system for the control of the hoist. The hoist has locking means (10), which in a locking position prevents the utilization of the hoist and in a release position permits the utilization thereof. An identifying system is associated with the locking means (10) for identifying the authorization of a user, whereby a release signal is delivered to the locking means in case of verified accepted authorization. A recording system having a memory unit and a timer is associated with the identifying system, the identity of the utilizer and the time of use being recorded in the memory unit at each occasion of use in order to accomplish a debiting based on time of use.

Catch apparatus for a rack lift, with a tooth wheel (2) engaging the rack and unrotatably mounted on the shaft (4), which also carries two friction members (16,18), which are spring tensioned (28) towards each other for mutual friction engagement, and of which one (16) is unrotatably carried by the shaft (4), and the other one (18) is glidingly supported (20) on the shaft but normally co-rotating through the frictional engagement, an inertia blocking mechanism (38,74) being arranged to stop the other friction member (18) at exceeding of a limit velocity of the shaft (4), for braking the shaft through the frictional engagement. The blocking mechanism includes a blocking member (54) which is suspended (44,46) for pendulum movement in a plane extending trans- versely to the shaft (4) in order to be clamped, when the limit velocoty is exceeded, between a fixed abut- ment (74) and an abutment (42) carried by the other friction member (18).

The invention concerns an arrangement for securing a lift car (1 ) that is part of an electrically driven lift at a predetermined level for, for example, service or maintenance, and for preventing unintentional motion of the lift car secured in this manner, whereby the lift car may be of the type that is arranged with a cage or platform for the transport of persons or material. In order to be able to stop the lift car immediately from the platform or cage of the lift car and essentially prevent unintentional driving of the lift car when it is located secured at a certain level, the arrangement comprises: a restraining arrangement comprising a restraint (13) that is supported by the lift car (1 ) arranged such that it can be placed into and removed from restraining interaction with an extended stationary interaction element (7) arranged to extend along the vertical pathway of the lift car, and which restraint when placed into restraining interaction locks the lift car to the stationary interaction element, a power-interruption device (31 ) that can be placed into and removed from a power- interrupting position whereby the power to a driving motor unit (8) that is part of the lift is interrupted when the power-interruption device is placed arranged in its power-interrupting position, in which the power-interruption device (31 ) is so arranged at the restraining arrangement (13, 7) that the said power-interruption device is located in its power- interrupting position when the restraint (13) has been set into restraining interaction with the extended stationary interaction element (7).

The invention concerns an elevator system comprising an elevator car (3) with a working platform (6) arranged for carrying people or materials and which by means of the interaction between a gear wheel and gear rack can be moved along an elongated generally vertical mast (1) constructed from a number of mast sections (2) mounted on top of each other. To facilitate the erection, tearing down and anchoringof the mast to a nearby building structure, the moving unit (1) comprises a passenger-carrying service and assembly platform (10), which, via a swing arm (16), is flexibly supported by the elevator car to allow a swivel action in a horizontal plane (C, D) relative to the elevator car (3).

摘要:
A wall module (1') to be joined to other similar wall modules for forming larger wall assemblies is primarily intended to be used for the covering of lifts and lift shafts. The module has a first connecting portion (3) extending in parallel to a complementary second connecting portion (5). An intermediate portion (7) connects the connecting portions (3, 5) to each other. Thereby, the first coupling portion (3) has a cross section in the form of an arcuate tongue, the other one (5) having the form of an arcuate groove. Two wall modules (1') are joined by placing one wall module at an angle with an already mounted wall module (1'), the opening of said arcuate groove being placed over the tip of the tongue, the wall module to be mounted then being turned, so that the tongue penetrates into the groove until the desired position has been reached. Preferably, all members are manufactured from extruded aluminum.

An actuating mechanism for a catch (3) of a hoist door (4) comprises a vertically displaceable operating member (16), which is associated with a vertically displaceable actuating member (46), by means of which the catch (3) may be released. A coupling mechanism is provided between the actuating member (46) and the operating member (16) and has a cam follower (36), which in engagement with a cam (56) locks the coupling mechanism in such a manner that a displacement of the operating member will be transferred to the actuating member (46) for the release of the door catch (3). When the cam (56) is absent no movement will be transferred to the actuating member (46). The cam (56) and the cam follower (36) are provided on a hoist cage at a landing, respectively, or vice versa, so that the door catch (3) may be released, only when the hoist cage is at a landing. The coupling mechanism is a toggle joint mechanism, having two pivotably connected link arms (28, 38), the cam follower (36) being associated with the common pivot (34) of the link arms (28, 38). The opposite ends of the link arms (28, 38) are connected to the operating member (16) and the actuating member (46), respectively.
