Introduction Les élingues en câble métallique sont un composant essentiel dans diverses applications de levage et de gréage en raison de leur durabilité., flexibilité, et une capacité de charge élevée. Une manipulation et un fonctionnement appropriés sont essentiels pour garantir la sécurité et l'efficacité lors des tâches de levage.. Ce guide vise à fournir des informations complètes sur les précautions essentielles et les meilleures pratiques d'utilisation du câble métallique. […]
je. Signaux unifiés pour les opérateurs et le personnel des transmissions Les opérateurs de grues à portique et le personnel des transmissions doivent utiliser des signaux standardisés et unifiés pour assurer une communication et une coordination efficaces.. Les opérateurs doivent monter ou descendre la cabine de commande à l'aide des échelles désignées. Avant de mettre sous tension, le contrôleur doit être tourné en position neutre. Le plancher de la cabine devrait […]
L'efficacité énergétique est une considération cruciale pour l'exploitation des grues automobiles. En optimisant les performances du moteur et en adoptant les meilleures pratiques, la consommation de carburant peut être considérablement réduite. Une stratégie efficace consiste à augmenter le taux de compression du moteur à sa valeur standard.. Pour les moteurs diesel, le taux de compression typique se situe entre 16:1 et 22:1. L'augmentation du taux de compression améliore […]
je. Reasonable Matching The tires at the front and rear, left and right of the machinery must be reasonably matched. The tires assembled on the same machinery should ensure the same brand, specification, structure, tread pattern, and load. Radial tires and bias-ply tires cannot be mixed; tires with different rim diameters, widths, or different cross-sectional […]
The lifting capacity of a tower crane refers to the weight that its hook can safely lift. This capacity includes the weight of the slings, lifting devices, and containers. The lifting capacity varies with the crane’s working radius. Donc, each crane is equipped with a unique lifting capacity chart corresponding to its operating radius, commonly […]
Installation and Acceptance Standards for Trolley Conductors I. Brackets Anti-corrosion TreatmentBrackets should be treated with anti-corrosion measures to prevent rust and deterioration over time. This is crucial as they are often exposed to various environmental conditions, such as moisture, poussière, and chemicals. Corrosion can weaken the structural integrity of the brackets, potentially leading to instability […]
Proper lubrication and maintenance of the crane’s walking mechanism are critical for ensuring the equipment’s longevity, fiabilité, and safe operation. This document provides comprehensive guidance on the lubrication and care of the crane’s walking components, including the reduction gears, wheel bearings, and open gear systems. Initial Setup and Reduction Gear Lubrication When the walking mechanism […]
je. Importance of Moment Limiters in Crane Safety Lifting equipment is a type of machinery with relatively high risks at construction sites. Once an accident occurs, it often leads to severe consequences with multiple casualties. Donc, the safety issues of lifting equipment have always been emphasized by relevant departments. The moment limiter is one of […]
je. Introduction to Bridge Crane Electrical Control and Maintenance Importance In the current field of lifting and hoisting, the bridge cranes used mostly adopt contact-controlled AC contactors for electrical control. Although this control method appears relatively old-fashioned in the current industrial electrical automation control field, due to its strong adaptability to harsh environments, the excellent […]
je. Importance of Torque Calculation Significance for Reducer LifeTorque calculation is of utmost importance when it comes to the lifespan of a reducer. The maximum torque value during acceleration (TP) needs to be carefully considered to ensure that it does not exceed the maximum load torque of the reducer. If the torque exceeds the rated […]
