The maximum boom angle for crawler cranes is a critical factor affecting their lifting capacity and operational safety, especially for long booms. Understanding the safe angle of the crane boom ensures the stability of the equipment and effectively prevents potential accidents. Additionally, being aware of the different types of crane booms can further enhance operational efficiency and safety.
Lattice boom crane
Lattice boom cranes can be widely used in lifting fields such as wind power construction, bridge construction, petrochemicals, and municipal engineering. Their unique design employs interconnected steel beams to form a truss structure that allows the boom to extend and retract. This design not only provides the superior strength required to lift heavy objects but also keeps the total weight of the crane relatively low. Additionally, being critical for long booms on crawler cranes, this truss structure enhances stability and operational efficiency in various lifting applications.
Typically, the maximum operating angle of a lattice boom crane is 70° to 80°. This angle range is critical because it ensures stable lifting capacity even at higher heights, thereby improving operational safety. These cranes are particularly suitable for heavy lifting applications where high load capacity and stability are critical, such as when building large structures or handling oversized materials.
Telescopic boom crane
Telescopic boom cranes are a versatile type of crane widely used in construction sites, docks, logistics parks, and other fields. They offer advantages such as flexibility, efficiency, and space-saving capabilities. Known for their rapid maneuverability, these cranes are ideal for construction sites that require quick adjustments to cope with unforeseen movements. As one of the prominent types of crane booms, telescopic boom cranes enhance operational efficiency and adaptability, making them essential for various lifting tasks in dynamic environments.
The principle of a telescopic boom crane is to drive the extension and retraction of the boom through a hydraulic system to achieve the adjustment of the boom height and length. The hydraulic system consists of parts such as the oil tank, hydraulic pump, hydraulic solenoid valve, hydraulic cylinder, oil pipes and hydraulic controller. When the operator operates the controller, the hydraulic pump starts, pressurizing hydraulic oil into the hydraulic cylinder, pushing the boom to move. Telescopic booms are made of durable materials such as aluminum or high-strength steel alloys, designed to withstand huge weights while maintaining structural integrity. The typical operating angle of these cranes is usually between 70°and 85°, which can provide optimal load security and stability during operation.
Articulated boom cranes
Articulated boom cranes, commonly known as knuckle boom cranes, feature an articulated boom composed of multiple interconnected sections. These sections are connected by hydraulic cylinders or knuckle joints, allowing the boom to bend and maneuver around tight spaces or obstacles. This unique ability makes articulated boom cranes particularly suitable for performing tasks that require precision and accessibility in challenging environments. Among the various types of crane booms, articulated boom cranes stand out for their versatility and capability to operate in confined areas, making them an excellent choice for specialized lifting applications.
Made of strong materials such as steel or aluminum, these cranes combine strength and flexibility. The range of motion of an articulated jib crane can vary depending on the model, starting at a minimum angle of 125 degrees and going up to a maximum angle of 180 degrees. This wide range can be used for a variety of applications, including tree pruning, material handling in tight areas, and general construction work involving multiple obstructions.
Summarize
With a maximum angle of 70° to 80°, lattice boom cranes are ideal for heavy lifting in construction and infrastructure projects. Telescopic boom cranes typically operate between 70° and 85°, providing the versatility and quick adjustment required in dynamic work environments. Articulated boom cranes have a range of motion from 125° to 180°. By adhering to these safe boom angles, operators can significantly reduce the risk of accidents, improve crane performance, and ensure project success. Being critical for long booms on crawler cranes, these safe boom angles also enhance stability and operational efficiency in various lifting scenarios.
