LD electric single beam bridge crane I. brief introduction LD electric single beam bridge crane (hereinafter referred to as the crane) is designed and manufactured according to the standard jb1306-2008. It is used together with CDI, MDI and other forms of electric hoist. It has become a light and small crane for rail operation. Its applicable lifting weight is 1-10 tons and its applicable span is 7.5 ~ 22.5 meters, The working environment temperature is in the range of - 25 ~ + 40 ℃. For the convenience of users, there are two operation forms: ground and control room, and the control room is also provided with two forms of end face and side door opening for users to choose. This product is a general-purpose crane, which is mostly used in machinery manufacturing, assembly, warehouse and other places. Its structural characteristics are as follows: 1. The main beam of metal structure adopts U-shaped channel steel formed by steel plate calendering, and then welded with I-beam to form a box shaped solid web beam. The cross beam is also rolled into U-shaped channel steel with steel plate, and then assembled and welded into box cross beam. For convenient storage and transportation. The main beam is connected with M20 bolts (45 steel) to form a bridge. 2. Electric hoist electric hoist can lift heavy objects and move laterally along the main beam. See the instructions of relevant electric hoist for its structural characteristics.
Product introduction of single beam crane
Single beam crane has the characteristics of reasonable structure and strong rigidity of the whole machine. The whole machine is matched with CD1 single speed electric hoist and MD1 double speed electric hoist. This product is a light and small lifting machine. This product belongs to the intermediate working system, and its lifting capacity is 1t-20t. The span is 7.5-31.5m. The working level is a3-a4, and the working ambient temperature is - 25 ℃ ~ 40 ℃
Features of single beam crane:
The crane with the pick-up device suspended on the lifting trolley or traveling hoist that can run along the bridge is called "bridge crane". The bridge crane whose two ends of the bridge are directly supported on the elevated track through the running device is called "bridge crane". Single beam crane is generally composed of bridge with crane running mechanism, electric hoist with lifting mechanism, electrical equipment, cab and so on. The shape of the single beam crane is like a single span flat slab bridge with two ends supported on two parallel overhead rails. The lifting mechanism of the single beam crane is used to vertically lift articles, and the electric hoist trolley is used to move laterally with load; The bridge and crane operating mechanism are used to move the lifting trolley and articles longitudinally, so as to transport and load and unload objects in a three-dimensional space within the span and the specified height.
Processing technology of single beam crane:
Crane metal structure (processing of bridge)
1. Firstly, the steel plate surface is derusted by shot blasting machine to improve the adhesion of paint.
2. For the camber of the welded joint between the web and the upper cover plate, according to the span process conditions of the crane, first use the corresponding quadratic curve, quartic curve and quadratic quartic superposition curve, calculate and select the point arch height by computer, make a template, and set out and blanking the web.
3. The splicing welding of the main beam shall be equipped with welders and reasonable welding process. Through symmetrical welding by two or four people, the current and welding speed shall be reasonably selected to reduce the welding deformation of the crane
4. For butt welds of main beam, end beam, web and upper and lower cover plates, automatic submerged arc welding shall be adopted for all longitudinal welds, and flaw detection shall be carried out after welding.
5. Setting out, positioning, lifting and turnover on the platform are adopted for the butt joint of bridge and portal main beam and end beam to ensure the geometric dimension and control the welding deformation.
instructions
Single beam cranes are widely used in workshops, factories, warehouses, stockyards and other places to lift goods. It is prohibited to use them in flammable, explosive and corrosive media. The single beam crane is equipped with ground and control room. There are two types of operating rooms, open and closed, which can be installed on the left or right respectively according to the actual situation. There are two kinds of entry directions: side and section, so as to meet the user's choice under different needs.
