Q:The construction elevator can not operate during the use of several stages of wind power

11, when the wind speed exceeds 20m/s and the bad weather, such as hail, not use the lift." I'm a construction elevator This is the norm It's about a six-stage wind by 20m/s.

Q:What's going on with the decline in construction lift

Check whether the brake work is valid.Check to see if there is any problem with holding the brake.

Q:Is the construction elevator a special equipment

Belong to special equipment construction lifter, but generally used as home building municipal engineering does not belong to the quality and technical supervision management, but belong to the administration of urban construction. Because the system of quality control unless invited, shall not be involved in military, aerospace, nuclear industry, mine, municipal, sea, railway locomotive hoisting machinery management.

Q:Why is the construction elevator not up to the roof

Construction elevators are often called construction elevators, but construction lifts include a broader definition, and construction platforms are part of the construction elevator series. Simple construction elevator is by car, driving mechanism, standard section, attached to the wall, chassis, fence, electrical system and so on several parts, manned cargo construction machinery is a frequently used in construction, because of its unique enclosure structure make it take up both comfort and safety, construction elevator is usually used with tower crane on the construction site, the average load in 1-3 tons, running speed is 1 to 60 m/min. The construction elevator of our country is more and more mature, and gradually goes to the international.

Q:Where is the location of the elevator in the project

Construction elevator location setting, need to take into consideration the situation of the scene and the layout of the building, should consider the following factors: To facilitate the conveyance of material transportation, choose the more spacious rooms in the layout of the floor as import and export; The outside of the elevator is as spacious as possible, with construction channels and materials. The construction materials are minimized in the floor, usually in the middle of the flat. The construction personnel are handy; Monomer building expansion joints at the junction, traffic between unit set up by the elevator capsules export operation platform is completed, so the corresponding reduced floor wall body of the reserved hole lien expansion joints

Q:How is the construction elevator installed

Construction elevator installation 1) the location of the elevator depends on the condition of the site and the equipment, so as far as possible, stay away from the overhead line and keep the safe distance specified. When the elevator is running, there is a lot of danger and should be avoided. 2) the order of installation is: 3) place the chassis on the base and the base pre-buried bolt, and the platform is placed on the chassis, and the basket is placed in the middle of the chassis. 4) to install the standard section, each installation of two standard sections (usually less than 8m) to be temporarily fixed. The wire rope shall be used for the use of the temporary cable, and the joints and supporting points shall be bolted and not tied with the lead wire. 5) the installation should alternate between the two columns. Node bolt specification must according to the aperture matching, not packing, found that the aperture position at the time, can not arbitrarily expanding, more can't to lead wire bundle, instead to avoid loose node deformation. 6) when installing the standard section, pay attention to the vertical degree of the guide, and the line of the guide line should not appear in the line of folding and too big clearance to prevent the collision from running. 7) when construction site conditions permit, it can be assembled on the ground and then hoisted on the whole to reduce the height of the work. Due to the design of the frame, the stress condition of the construction is only considered, so before the whole moving up, the counter can be temporarily strengthened to enhance the bending capacity of the nodes.

Q:Gear rack driven

Driven by two or three worm gear reducers, the ladder cage is a load bearing unit, and gravity is carried by a rack. At rest, the force point is in the meshing of the gear and rack.

Q:Construction elevator positioning should consider which problems

It is convenient to install the wall with the wall

Q:The maximum allowable deviation of the vertical is the vertical degree when the construction elevator is installed

5 kinds of circumstances. 1: the height of the elevator guide frame is less than 70 meters, and the vertical deviation should not be greater than one in 1000 of the height of the guide frame. (assuming the rail frame is 70 meters high, the deviation cannot be greater than 70mm) 2: the rail frame is greater than 70 meters and is less than 100 meters, and the deviation is less than or equal to 70 mm. 3: the guide frame is larger than 100 meters and is less than 150 meters. The deviation is less than or equal to 90 mm. 4: the guide frame is larger than 150 meters is less than or equal to 200 meters. The deviation is less than or equal to 110 mm. 5: the guide frame is greater than 200 meters, and the deviation is less than 130 mm. This is based on the requirement of 5.2.2.1 from GB10054 to 2005. (it used to be a direct copy.)

Q:Does the building height not exceed 40 meters must install the construction elevator?

There is no hard and fast rules, but the construction unit according to the time limit for a project, the delivery of materials, construction personnel and management personnel, including supervision, need to install the vertical transportation machinery (including goods dual-purpose ladder).
