it is easy to cause the ring gear Vibrations.

metallurgical electric hoist Cone Line Motor: Lifting   motor with large starting torque tapered rotor brake asynchronous motor, no   external brake. 25% duty cycle motors, motor with Class B or Class F insulation,electrical protection class IP44 / IP54. Button switch: Hand operating lightweight and flexible, grabbing cranes sub-corded and wireless remote manipulation of two ways.

Under normal circumstances

electric magnetic overhead craneThe drive device is used to drive working organs of power equipment. Common drive electric drive, internal combustion engine drive and human power, etc. Electrical energy is clean and economic energy, grab bucket crane electricity is the main drive of the modern crane type

magnet crane

Check the installation test installation commissioning and inspection of the project magnet crane criteria in Table 1 , Table 1 in the inspection requirements on the one hand assessment of the basic properties of electric hoist itself , while also testing between levels of installation , its purpose is to ensure that electric shade Lo safe and reliable operation of First Instance into being . Bt $ f electric hoists and other lifting set together the biggest difference is mostly for ground operations , with no specialized operator , which is safe , safe inspection compactor is extremely unfavorable , crane supplier it is necessary to strengthen the routine inspection.

According to the statistics, machinery processing industry production 1 ton every product, electric wire rope hoists in the process of processing to loading and unloading, carrying 50 tons of material in the process of casting to carrying 80 tons of materials. 1 tonnes per smelting in metallurgical industry, it is necessary to carry 9 tons of raw material, the workshop between the capacity of 63 tons, workshop within the capacity of 160 tons. Lifting transportation cost also has a higher proportion in the traditional industries, foundry crane such as machinery manufacturing for lifting transportation costs 15-30% of all production costs, metallurgical industry for lifting transportation costs 35-45% of the total production cost, loading and unloading of goods storage transportation industry relies on lifting transportation machinery

electric overhead crane

Calculating local bending moment caused by wheel pressure in the first quarter. When CHS center of gravity axis of the intersection point of the string section centroid eccentricity, double girder overhead travelling crane to calculate its impact. Check the strength of each bar, hydraulic components and the stability of the axial compression member and fatigue of the bar. The node must carry on the strength and fatigue calculation. To check girder crane beam and brake structure deformation. The slenderness ratio of member to conform to the requirements of the specification. Crane beam arch camber to reduce large span crane beam may arise when using large downward deflection phenomenon, electric overhead crane to avoid affecting the normal operation of the crane, and in the production of crane beam, beam arch up in advance. When deciding the arch since size, want to consider the convenience of crane rail laid.

over head cranes

At present, China produces most of the use of overhead cranes were driven approach , it has light weight , workshop crane easy installation and maintenance. Transitional institutions throughout crane driven carts before and after the workshop along the length direction.Crane metal body materials, primarily steel. The manufacture of ordinary carbon steel eot crane  metal most commonly used materials, according to the chemical composition and deoxidation method, industrial overhead cranes is divided into four grades. Crane metal structure provides important bearing member using metal body components for general crane, when the design temperature not lower than , allowing the use of boiling steel, working-level A7 and overhead gantry crane  metal structure should  killed steelor special killed steel Need to reduce the structural weight, you can use 16Mn or 15MnTI, for outdoor work influenced by the temperature of the crane, such as gantry crane, over head cranes with its metal structure must be carefully chosen.

grab bucket crane

For an enterprise, it shall strictly implement the production safety law of the People's Republic of China, the special equipment safety supervision regulations, grab bucket crane and laws and regulations concerning production safety. Develop and implement the responsibility system for production safety of the hoisting machinery safety management is not only the category of enterprise equipment management, is an important content of safety production management, thus establish and improve the safe production responsibility system, the implementation of safety management is a precondition for the safe operation of the hoisting machinery and the important guarantee. The safe production responsibility system is the experience of years of production practice and summary, bridge cranes is the enterprise one of the most basic and effective security system.
