Mobile scaffold ( Jiangsu mobile scaffolding rental) Are the main frame, horizontal box, cross brace, scaffolding, adjustable base, etc. Cross bar is also called diagonal member, is the longitudinal connecting two pair of door frame type cross rod. Bar ends flattening part with pin holes and assembled with lock pin lock on the door frame stud. Surface treatment: electroplating ( Cold galvanizing) , leaching zinc ( Hot dip galvanized) Castor: also known as the land wheel, can be installed at the bottom of the mobile scaffold, mobile scaffold. Can be used as mechanical and electrical installation. Paint finish. Equipment maintenance. Advertising activities of the working platform. Castor is 6 inches belt brake, is easy to use. Mobile flexible. The characteristics of safe and reliable. Mobile scaffold ( Jiangsu mobile scaffolding rental) The divisions of material classification: according to the bar 1) A single specification of steel pipe scaffold. It USES only one kind of specifications of steel pipe, such as the fastener type steel pipe scaffold, using only Ф 48 & times; 3. 5 the welded steel pipe. ( 2) A variety of specifications of steel pipe combination of scaffolding. It is composed of two or more different specifications of steel pipe, such as gantry scaffolding. ( 3) Give priority to with steel tube scaffold. I. e. , according to the steel tube is given priority to, supplemented by other steel bar of the scaffold, such as a channel steel top or base of scaffolding, have connection steel scaffolding, etc. Divided according to the vertical force mode ( 1) By contact friction force. That rely on node interface after compaction friction reaction to support rail load and its to the stud, such as the role of the fasteners, created by the positive pressure of tightening bolts friction; ( 2) By weld force. Most of the rail and socket connection is in this way, the door frame also belong to this way; ( 3) Direct pressure force. This way, see more at bar shelved in the vertical bar at the top of the scaffold; ( 4) Shear force on the pin rod. In which vertical pin rod through the cross bar connecting plate and the vertical rod, pin holes to realize connection double shear effect. In the stud and vertical shaft coupling, there are 3 kinds of force transmission way: ( 1) Handing down power socket docking. The poling docking, connecting rod or socket pipe is used to ensure the docking in good condition; ( 2) Pin rod connecting pin rod shearing force; ( 3) The meshing force of screw connection. The external thread of inner tube and outer ( Set) The internal thread of meshing force. Among them after more than two kinds of force transmission way used to regulate the stud connection to the height requirement. According to the principle of fixation method and furnish division ( 1) Weldment distance connection: the connection in the distance on the bar set, bar length, join point spacing shape; ( 2) Variable distance connection: attachment for single pieces, by tightening bolt clamping on any part of the bar. Divided according to the operation mode, 1) Insert the matter; ( 2) Tighten the bolt.
