The utility model provides the trackless construction elevator to compare with existing construction elevator, has following outstanding advantage and good effect.

1, because need not to install derrick, track, compares with construction elevator with existing skyscraper, can save about 90% steel of elevator gross weight, the cost decrease of elevator; The installation of this elevator, increase and remove and simple and do not need the basis rapidly, its installation, increase and remove and freight also significantly reduces;

2, feasible, suitable.

1. the arrangement of elevator is easy to select.The skyscraper civil engineering stage, elevator all is idle or is used as and draws the rubbish road to use generally speaking, therefore elevator is the desirable preferred location that this elevator is installed, when treating that formal elevator begins to install, engineering is basically completed, the tailing in work of only remaining lower which floor is got ready as long as in advance used building materials is transported, and elevator will not influence normal construction after removing; The courtyard of building or the outdoor space that has the above body of wall in two sides to surround are all to be installation sites preferably in addition.

2. elevator slightly rocking in lifting process do not have any influence to manned loading in the normal construction.When the carrying means of this elevator drives the vertical building structure oscilaltion continuously operation of cab edge, because building structure has bigger deviation at relative rail road or derrick aspect squareness, the planeness, therefore cab will shake, but as long as disappear sudden change place of fabric structure deviation flat by the method for shaving cutter and mending ash, these work be accomplish easily in the building operation and take a lot of work few, even building structure has the very big horizontal displacement deviation of 20mm in the high scope of 2m.When cab operates in this scope, because the runner of corresponding offset deviation one side and the runner on its opposite all will be compressed or be loosened simultaneously on the cab at this moment, and the reason that has inertia owing to cab, the rocking displacement and will be not more than 10mm of cab, and the general 60cm/s of the rising or falling speed of construction elevator, its liter or fall the 2m rise from needing for 3 seconds approximately, so the cab speed of rocking only is about about 3.3mm/s.This will not influence the manned loading in the construction.

3, safety, reliable.This elevator can adopt the safety guard of cam disconnected rope anti-dropping safety device and multiple existing elevator, and therefore safety is guaranteed.

4, use is not influenced by inclement weather.When this elevator is satisfied with not to be subjected to the influence of weather such as blowing and raining, when particularly blowing hard when indoor, general vertical transport construction mechanism all can not use, this moment, engineering was forced to stop work, and this elevator this moment still can normal manned loading, still can satisfy normally carrying out of indoor decorating work.

5, purposes increases.In the time of in this elevator is installed on elevator, as long as when the design of cab body, consider the installation of formal elevator simultaneously; Reserve the position of the track etc. of formal elevator, this elevator also can be used for work such as the installation of formal elevator rail etc. and adjustment.
