Ensuring a safe working environment involves the detailed calculation of the safety factor, incorporating various parameters to determine the margin of safety. Determining Load Factors Consideration of load factors, including static and dynamic loads, impact, and potential variations, helps in establishing...
On the Dynamic Factor Φ4 for the Consideration of Driving over Unevenesses according to DIN EN 13001-2 "DIN EN 13001, Crane safety, General design" is a basic standard to ensure the safety of cranes by proof of integrity by means of calculation. The standard......
Before delving into the calculation methods, it’s essential to comprehend crane load ratings. Load ratings, categorized into static, dynamic, and suspended loads, determine the maximum weight a crane can lift without compromising safety. Each type of load rating has specific considerations, making i...
By calculation, the natural frequency and modal shape of the standard section, as well as the lifespan, damage, and safety factor of the frame section, were obtained. It can be seen that the standard section has good structural stability and can maintain relative balance under...
(1)Safety factor: Main design is greater than 2.0,Vacuum system pressure value for calculation is 60%,The actual peak pressure can reach 85% degrees,Set aside about 40% degrees. (2)Board of overhang To calculated according to the board overhang. ...
- Our operations are subject to extensive environmental and health and safety laws and regulations, which impose limitations on the discharge of pollutants into the ground, air and water and establish standards for the generation, treatment, use, storage and disposal of solid and hazardous wastes. ...
In these studies, the actual calculation of the hoisting process is estimated by an safety factor and the movements and forces cannot be obtain accurately under the given wave load, sea current load, wind load and ship motion[12]. The movement and dynamic response of the ship and hoisting ...
The roof conditions of 18124 working face in Pan’er Coal Mine are complex, the strength of rock strata is low, and safety accidents such as roof collapse are easy to occur, which leaves potential safety hazards for large-scale transportation of monorail crane. In order to solve such safety...
Buffer: The size of the vehicle are equipped with a buffer, with the absorption of the operating body of the energy and reduce the impact of good performance, the protection of the collision force is less than the current standard calculation. The center of the cart is 0.76...
poor planning or miscalculations regarding anticipated load conditions, poor decision-making during crane operation, and simply carelessness. Dragging and extrication events constitute overload conditions and can cause several types of failure modes and resulting damage, such as the creation of grooves on...
