Electric single girder crane girder institutional analysis

Electric single girderelectric hoiststructure has 70 years of history in the form of a single beam of variety, such as: add truss beam, I-beam tube plus, plus a triangular box girder beams, rectangular box girder beam plus more.
These single girder crane girder composite section has many deficiencies, such as the thickness of the beam height is too high, and cover the same web (n-type orange), material utilization is not reasonable, composite section of the welding process and repression increase the cost of production.
In recent years, the domestic electric single girder crane (LDA type 1 to 20 ton electric single girderElectric wire rope hoist http://www.cn-cranes.com/html/danliang/40.html) girder section some new patterns. In this paper, local bending stress flat flange steel plate at the edge of the wing hoist wheel pressure effects arising from analysis.

First was the distribution of local bending stresses measured by simulation, structural analysis and then use the MAS program to compute the finite element model analysis, the maximum stress calculation charts and curves. From the experimental results and finite element analysis results obtained local maximum bending stress flange plate mainly in the loading point and the corresponding free edges and roots.

Crane parts of the bearing detailing

In the Wall-traveling Jib Crane or the gear unit is in the wheel bearing housing, if the inner race of the bearing and the radial direction of the radial thrust bearing is a fixed position of the shaft, so in these shafts when the shaft is rotated, the device an outer race means are fixed on the bearing bore, which is fixed on the bearing means of the bearing sleeve inside, also according to the type and manner of installation of the bearing means, so that both is used according to the demand determined.
Lifting accessories bearing device fixed to determine the way in time, but also need to take into account the purpose and structure of the organization, as well as transmission equipment type, between the bearing type of bearing, the force of nature, the use of the size and direction of the device distance, bearing on the device as well as the general arrangement and certain conditions of use.

Cantilever crane (LX-A electric single girder overhead crane http://www.cn-cranes.com/html/xbd/33.html) using the "Job Status switch" position, we must ensure that hanging with the use of consistent with the arm in the form of a job, or it may cause damage to the crane or accident. Because of different models, the above will vary, according to some automatic overload prevention device Instructions executed. After the operation, the cantilever Electric wire rope hoist boom sections should be fully retracted and placed on the front of the boom stand, hang hook.
  Bearings are single girder crane very important accessory, lifting accessories bearing fixed at the time of installation and there are many considerations to be primarily a crane after the bearing type selected for each axis and determine the size of the bearing on the shaft must be selected or the bearing bore on ways and means fixing method, the method is also very important.

Truck Crane

Electric wire rope hoist, the country with QY said that if QY20 / 20t double girder gantry crane (truck crane). The crane mounted on a general or special vehicle chassis chassis performance is equivalent to the total weight of the vehicle the same truck, meet the technical requirements of road vehicles, which can be used freely on all types of roads. Such cranes are generally available on both cab off, you must extend the legs when the job is stable. From the weight of a large range available from 8 tons to 1,000 tons, the number of axles chassis, from 2 to 10. Is the largest output, the most widely used type of crane.

Electric hoist

There Column, wall-mounted and balanced electric hoist three forms.
① column cantilever Electric wire rope hoist boom can be fixed in a given column around the base of the swing, or cantilever column and turn rigid, support within the base together with respect to the vertical centerline of rotation composed by columns and cantilever cranes. It applies from the weight of small, round or job scope of services sector occasions. General machine tools and other artifacts for chucking and handling. Column cantilever crane use more electric chain hoist as lifting mechanism and operation mechanism, less use of wire rope hoist and chain hoists. Rotation and horizontal movement to use more manual work, only play a greater weight
When using electric.
② wallr electric hoist is fixed to the wall of the cantilever crane or jib cranes can along the wall or on an elevated track running other supporting structure. Wall crane line using the occasion to span large building height larger workshop or warehouse, close to the wall when lifting operations more frequently near the best. Cranes line the walls and above the multi-beam bridge crane or with the use of the service on a wall near a rectangular space, responsible for lifting small light objects, large borne by the beam or bridge crane.

③ balance electric hoist known as balance suspended, it is the use of four-bar linkage principle to make the load and the counterweight constitute a balanced system, you can use a variety of spreader flexible and easily lifting loads in three-dimensional space. Balance electric hoist lightweight and flexible, it is an ideal for lifting small items of lifting equipment, is widely used in factory floor machine loading and unloading, inter-process, automatic line, production line of the workpiece, lifting sand box, parts assembly, and stations, docks, warehouses and other occasions
