Always refer to the load chart provided by the manufacturer, as it shows the safe working limits under different conditions. For example, a crane might have a maximum capacity of 50 tons at a short radius, but only 10 tons at full extension.

Стрела крана — это его основная组成部分, и ее конструкция может быть телескопической или решетчатой. Телескопические стрелы популярны для автомобильных кранов due to their quick setup and versatility. Они состоят из нескольких секций, которые выдвигаются гидравлически, allowing for adjustable length. Решетчатые стрелы lighter and can achieve greater heights, but they take longer to assemble and are less mobile. Choose based on your need for speed versus reach.

Двигатель и трансмиссия также crucial. Most automotive cranes are powered by diesel engines for their torque and reliability. Look for engines that meet emission standards (e.g., Euro 6) to avoid regulatory issues and reduce environmental impact. Transmission should provide smooth power delivery, with options for both manual and automatic controls. Four-wheel drive might be necessary for off-road or rough terrain operations.

Системы управления have advanced significantly. Modern cranes often feature electronic control systems that allow for precise movements and safety enhancements. For instance, load moment indicators (LMI) continuously monitor the load and boom position to prevent overloading. Some models offer remote control operation, which can improve safety by allowing the operator to work from a distance. Ensure that the controls are user-friendly and compatible with your team's skill level.

Additional features to consider include outriggers for stability, which can be hydraulic or manual. Hydraulic outriggers allow for faster setup and leveling on uneven ground. Also, check for auxiliary functions like winches or hooks that might be useful for specific tasks. Maintenance aspects are vital; easy access to components for servicing can reduce downtime and costs.

In summary, a thorough review of technical specifications will help you match the crane to your project requirements. Don't hesitate to consult with experts or request demonstrations from suppliers to see the equipment in action.
