No matter what the trend of the times and the fashion of society are, people can always rely on their noble qualities to transcend the times and society and follow their own right path. Everyone is running around chasing competition for refrigerators, cars, and houses. This is the trend of our era. What is characteristic is that there are many people who do not pursue these material things. They pursue ideals and truth and gain inner freedom and peace. Einstein
The crane uses the same type of wire rope electric hoist as the lifting device. The mechanism forms a three-dimensional working space by combining the up and down movement of the lifting hook, the left and right movement of the trolley, and the forward and backward movement of the crane trolley to realize operations such as moving and turning the lifted objects.
Widely used in docks, warehouses, construction sites and other open space working conditions. The crane is suitable for working at a working level, generally working outdoors, and the large and small truck operation and lifting mechanisms are equipped with rainproof covers. The working environment temperature ranges from ℃ to ℃, and the average temperature within an hour does not exceed ℃. When the average temperature within an hour exceeds ℃, the relative humidity is allowed to be temporarily high, and the relative humidity does not exceed ℃ at a temperature of ℃. The power supply of the crane is three-phase AC, and the rated frequency is. The rated voltage is. The upper and lower limits of the allowable voltage fluctuation of the motor are, and the internal voltage loss of the crane is not greater than. The electric hoist gantry crane is mainly composed of the electric hoist electric control system of the steel structure gantry trolley operating mechanism.
The main beam is the main load-bearing component of the hoist crane, and it is also the running track of the suspended electric hoist. The main beam is made of cold-formed steel plate, grooved inclined cover plate stiffener and I-beam welded into a solid web beam or steel plate welded into a box beam. The main beam is made into an upper arch shape as required, and the upper camber of the main beam should be (/~ the maximum upper camber should be located in the middle/range of the span. The electric hoist trolley runs on the I-beam flange. When the rated lifting capacity and The downward deflection caused by the hoist's dead weight at the mid-span shall not be lower than the horizontal line, and there will be no permanent deformation during normal operation. There are saddle seats connected to the legs on both sides of the span of the main beam, and there are rectangular steel plate connecting flanges. Both ends of the main beam There is a buffer at the bottom to ensure the safe operation of the trolley on the main beam. The ground beam is the basis for supporting the main beam and the load. It is also the link between the main beam and the operating mechanism. It is one of the main load-bearing components of the crane's metal structure. It is mainly composed of The groove and steel plate are assembled or welded into a box-shaped structure, which has the characteristics of light structure, good rigidity, beautiful appearance and good welding process performance. The end of the floor beam is equipped with a buffer. When the lifting capacity is large, the floor beam adopts an angle Box wheel structure, the corner box wheel and the ground beam are connected by bending plate positioning key bolts, a bending plate tooling that improves the quality and work efficiency of bending plate manufacturing.
The legs are isosceles trapezoids welded from steel plates Or right-angled trapezoidal cross-section box-shaped columns, with flanges of unequal width welded up and down the column. The upper flange is wider and the lower flange is narrower, which increases the strength, stiffness and stability of the mast. When the span is larger than meters, it is designed to improve the operating effect of the cart. There is a pair of flexible legs. The main beam and the saddle seats symmetrically arranged on both sides of the main beam fasten the two flanges with bolts, and make the two legs narrow at the top and wide at the bottom to form a certain angle, forming a glyph structure, which improves the The stability of the crane. The steel plate flanges between the legs and the ground beam are connected by bolts. The structure is simple, easy to install, and easy to transport and store. The ladder platform is bent and formed from steel pipe angle steel and other shaped steel. The platform is paved with anti-slip pattern steel plates. The bottom of the platform There is a fence railing with a height of , and two horizontal crossbars spaced . The angle between the inclined ladder and the horizontal plane is degrees or degrees. There is also a straight ladder for ground operation, and the step spacing is about ~, all The distance between the steps should be equal, and the width of the straight ladder should not be less than. When the height is greater than that, a safety ring with a diameter of ~ should be installed from the starting point. The driver's cab is generally closed. The top of the driver's cab can bear at least the static load, and the clearance height inside the driver's cab should not be less than.< br/> Because the specific models of product production batches are different, the above pictures are for reference only.
