lda single-girder overhead crane _ _ Henan Henan lda type gravity (view) by Crane Co., Ltd., Henan Province gravity. Gravity of Henan Crane Co. (www.zlqzj.com.cn) is specialized in the "single and double girder gantry crane, small light lifting equipment, lifting accessories, electric hoist." Enterprises, the company adhering to the "integrity of management , hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Hulu Jun. Single-girder overhead crane bridge girder beam or multi-use word combinations section of steel type and steel. Lifting trolley often chain hoists, electric hoist or hoist lifting mechanism components as assembled. Lifting the car on a single beam movement. Electric single girder crane design, manufacturing is in accordance with GB3811-86 "Crane design specifications" and JB / T1306-94 "LD electric single girder crane" and other relevant provisions of the standard. And CD1, MD1 electric hoist and other forms of supporting the use of rail running into a light crane, which applies to 20 tons from the weight below, ambient temperature within the range of -25 ℃ ~ 40 ℃. 1.1 The main purpose of the crane electric single girder cranes for general-purpose crane lda single-girder crane, used for transporting materials within a fixed cross between mechanical manufacturing, assembly, material yard, warehouse, installation and maintenance of equipment. Electric single girder crane is not available for work under the following conditions: the risk of explosion and fire hazardous environments; relative humidity greater than 85% of the sites and full of corrosive gas environment; lifting the molten metal, toxic or flammable and explosive materials. If you need to work Guangxi lda electric single girder crane under the above conditions must be in accordance with relevant standards and regulations, specifically designed and manufactured. 1.2 The main structure and performance of LD electric single girder crane is mainly composed of bridge, electric hoists, traveling mechanism, electrical equipment four major components. Some of the major bridge girder, beams, car conductive frame, cab, and other accessory components. The main use of steel girder spliced ??into a U-shaped, and then with a box beam welding solid web beams, and in accordance with the corresponding standard pre-camber; using steel beams are welded into a box, the box-type beam boring to install wheel group; between the main and cross beams using webs form and join and become one with the bolt. Monopole trolley line in normal operation should be done regularly checked, because the electrical equipment is a major industrial and mining production tools each, a slight mistake will directly affect the production efficiency of the plant. Check the trolley line should be in place to check whether a joint is loose every six meters, disengaged, checking electrical conductivity, should check whether the moving parts of rotating flexible tension spring whether fatigue, brush wear, etc. (these conditions will affect to track the performance of the trolley line conductivity and electrical conductivity should promptly make adjustments). When the holidays equipment refurbishment period, the guide catheter prolapse appliances, electrical inspection guide roller brush wear lda single-girder overhead crane, such as brushes extend the effective length of less than the specified amount to the timely replacement, guide roller deformation serious, should also replacement to maintain good contact is operating normally and brush electrical conductivity, and inventory causes. Security trolley line all components, the brush is the only normal wear parts. ? For severe corrosive gas environment still need to check the bracket, hanging folders, tractor rusting situation; and to take timely measures coated with rust-proof material?. Trolley line using spaces? Eg for infrastructure. Do not shock hit pressure transmission catheter? Even allowed to place heavy objects on the power transmission conduit. Prevent transmission conduit crack deformation? Affect? ??Accidents. Infrastructure completed, should immediately remove the catheter on the transmission infrastructure garbage. When properly maintained, the staff are not allowed to be on foot transmission catheter or stent, to prevent the destruction of the entire line of flatness and accidents.
