Definitions
- the invention relates to a construction hoist with a three-sided mast single mast pieces connected to each other via connecting bolts in the area the corner posts of the mast are connectable, and with one along two Cornerstay sliding, equipped with a travel drive platform, the one switching the traction sensor for each one between two Mast pieces provided switching piece, exclusively by the Connecting screw of the two mast pieces in the area of the platform turned off Eckstehers is held in a position detectable by the sensor.
- the invention is therefore the object of a construction hoist the beginning described type so that with comparatively simple constructive Means secure monitoring of the mast union with a Reliable detection of the mast end can be connected.
- the invention solves the task by the fact that the mast pieces in in itself known manner aligned, in the joint area between the mast pieces with Carrying distance from each other end safety edges and that the distance between each two of the arranged in the region of the sensor switching strips the loose, with the help of the connecting screw from below against the screw holder the lower of the two mast pieces clamped contact piece can be bridged.
- the invention advantageously exploits the fact that it is at least at a group of construction hoists is known, the mast for clamping To provide control switches with a ruler, which by flush Safety edges of the poles is formed, for easy monitoring of Mast gland made by the axial distance between the safety edges bridged directly juxtaposed mast pieces by the contact piece is, so that in a proper Mastverschraubung a on the Ruler results in continuous scanning bar for the sensor of the driving platform.
- the contact piece can Safety bar clearance only if the connecting screw is properly tightened bridged.
- the detail shown construction hoist has a three-sided mast. 1 on, which is composed of individual mast pieces 2.
- a driving platform 4 slidably guided, whose Drive 5 drives a pinion 6, which with a rack 7 along a the corner post 3 combs.
- the individual mast pieces 2, the corresponding sections bear the rack 7 are bolted together in their joint area.
- the connecting screws 8 connecting struts 9 of the corner post 3 prevail, the connecting screw 10 engages in the area of the Fahrbühne 4 turned Eckstehers 11 in a through hole of welded screw receptacles 12 a, as shown in particular in FIG. 3 can be removed.
- the mast pieces 2 carry between the Eckstehem 3 aligned Safety edges 13, in the joint area between the mast pieces 2 at a distance end from each other. These are complementary to a ruler across the mast height Safety edges 13 are used in known construction hoists for clamping of control switches, for example, the breakpoints for the platform in different Set heights.
- the safety edges 13 opposite is located on the platform 4, a sensor 14, the switching strips 13 z. B. inductive scans.
- the sensor 14 detects the End of a switching strip 13, the traction drive 5 is turned off.
- Fig. 3 while the Mounting arm 16 from below against the screw holder 12 of each clamped lower of the two mast pieces 2, so that the bridging position of the contact piece 15 is given only when the nut 17 of the Connecting screw 10 is tightened accordingly.
