A single beam crane is a type of lifting machine that is a type of machine that circulates and intermittently moves. The work cycle includes extracting the extract from the object to the object, then moving it horizontally to the specified position for the purpose of picking and dropping the goods, and then performing a reverse motion so that the extraction device returns to its original position in the next cycle.
Generally, the hoisting machinery consists of a lifting mechanism (up and down movement of goods), an operating mechanism (lifting machine), a luffing mechanism and a rotating mechanism (moving the goods horizontally),best port crane supplier, a combined metal mechanism, a power unit, and a control C. Control and necessary auxiliary equipment.
Single-girder cranes used in bridge construction can be divided into light and small lifting equipment, bridge cranes and boom cranes according to their structure and performance. Light and small lifting equipment such as Jack, hoist, winch, etc. Bridge cranes, such as beam cranes, gantry cranes, etc. Arm cranes such as fixed slewing cranes, tower cranes, truck cranes, tires, crawler cranes, etc.
Single beam crane A lifting mechanism with a certain range of vertical lifting and horizontal lifting. It is also known as a crane. It is a material handler. The working characteristic of the crane is to perform intermittent movements, that is, to alternately work in the working cycle by taking action, moving and unloading mechanisms.
The orange used for irrigation in ancient China was the prototype of a cantilever crane. In the fourteenth century, a rotary crane was driven by human and animal power in Western Europe. At the beginning of the 19th century, bridge cranes appeared. The important wear parts of the crane, such as shafts, gears, cranes, etc., began to be made of metal materials and began to use hydraulic transmission. In the late nineteenth century, steam-driven cranes gradually replaced hydraulic cranes. Since the 1920s, with the rapid development of the power industry and the internal combustion engine industry, various cranes driven by electric motors or internal combustion engines have basically taken shape.
The single beam crane mainly includes a lifting mechanism, an operating mechanism, a luffing mechanism, a rotating mechanism and a metal structure. The crane structure is the basic working mechanism of the crane. They are mostly composed of suspension systems and winches, and are also lifted by hydraulic systems.
The operating mechanism is used to move the heavy object horizontally horizontally or to adjust the working position of the crane, usually consisting of an electric motor, a speed reducer, a brake and a wheel. The luffing mechanism is only mounted on the jib crane, the amplitude of the jib is reduced, the amplitude is increased, the balance is enlarged, and the unbalanced amplitude is the slewing mechanism is used for a swivel arm, which consists of a drive unit and a slewing bearing unit. The metal structure is the skeleton of the crane. The main load-bearing components, such as bridges, booms and door frames, may be box-shaped or truss structures, web structures and some available steel as support beams.
