What are knuckle booms used for?

The knuckle boom crane is a convenient and efficient product, which can be moved to the designated position conveniently and quickly during the working process, so as to reduce the working time and improve the working efficiency.

 

Folding boom cranes are widely used for lifting and handling machinery in ports, workshops, construction sites and other places.

 

The folding boom crane is simple and fast to install and more flexible in the process of use. It is designed in sections, convenient to install and transport, and can be customized.

 

The folding boom crane is flexible and versatile, especially suitable for fragile items. It optimizes the assembly process of those items that need to be transferred quickly with high precision; The folding jib crane products are mostly used for auxiliary work, and are mostly used in various industries including engineering machinery, electronic manufacturing, airport, metal processing, automobile parts, etc. The intelligent folding jib crane saves working time to the greatest extent and reduces the overall cost.

How does a knuckle boom crane work?

The main working power of the knuckle boom crane is hydraulic drive. The hydraulic system consists of hydraulic oil tank, oil pump, valve group, hydraulic oil cylinder, hydraulic motor and hydraulic pipeline. The oil pump gets its power from the car engine through the power take-off,

Using hydraulic oil as the medium, the flow direction of hydraulic oil is controlled by the valve group to control the telescopic and luffing of the boom and the rotation of the crane.

 

The biggest working feature of the knuckle-boom crane is the telescoping with load.  When working, the boom is supported, and the goods are transported up and down by the wire rope. The biggest feature is that the boom is long and hoisting high. The folding arm crane has two sets of luffing cylinders. One set of luffing cylinders has the same function as the luffing cylinders of the truck crane, while the other set of luffing cylinders is used to lift cargo. Because the telescopic boom is also driven by the oil cylinder, the driving force is large, the telescopic boom can be pushed and retracted even when the hoisting load is heavy. Therefore, the advantages of the folding arm hanging in the narrow and low space are obvious!

An 8-ton knuckle crane lift refers to the lifting capacity of a knuckle boom crane, which is capable of lifting up to 8 metric tons or 8,000 kilograms of weight. A knuckle crane lift is performed using a knuckle boom crane, which is also known as an articulated crane or a loader crane.

The knuckle boom crane is designed with a series of hinged sections that allow the boom to fold and unfold in a way that resembles the motion of a finger joint. This design provides the crane with greater flexibility and maneuverability, making it useful for lifting and moving loads in a variety of positions and angles.

The operator of the knuckle boom crane controls the crane from a control station located near the base of the crane or from a remote control unit. The operator can extend or retract the crane boom and adjust the angle of the boom to lift and move the load to the desired location.

In addition to lifting loads, knuckle boom cranes can also be equipped with additional tools such as buckets or grapples to perform tasks such as material handling or debris removal.

Overall, an 8-ton knuckle crane lift is a valuable tool for industries such as construction, manufacturing, and logistics, where heavy loads need to be lifted and moved quickly and efficiently.

What is the difference between a knuckle boom and a crane?

A knuckle boom is a type of crane, also known as an articulated crane or a loader crane. The main difference between a knuckle boom and a traditional crane lies in their design and functionality.

A traditional crane typically consists of a single boom arm that extends from the base of the crane and lifts loads using a hook or a similar attachment. It is often mounted on a fixed platform, such as a tower or a truck.

In contrast, a knuckle boom crane has a multi-segmented, hinged boom that can fold and unfold like a finger joint. This design provides the crane with greater flexibility and maneuverability, making it useful for lifting and moving loads in a variety of positions and angles.

The knuckle boom crane can also be mounted on various platforms, including trucks, boats, or trailers. It is often used in applications where space is limited or access is difficult, such as in urban construction sites or indoor facilities.

Overall, while both traditional cranes and knuckle boom cranes are used for lifting and moving heavy loads, the knuckle boom crane provides greater flexibility and versatility due to its hinged boom design.

What is the advantage of a knuckle boom crane?

Greater reach and height: Knuckle boom cranes can reach higher and further than traditional cranes due to their multi-segmented design. This allows for more precise placement of loads and can reduce the need for additional equipment or manpower.

Increased safety: The flexible design of the knuckle boom crane allows for safer operation as it reduces the risk of collision or entanglement with nearby objects or structures. In addition, the precise controls and maneuverability of the crane can help reduce the risk of accidents or injuries on the job site.

Reduced downtime: The ability of the knuckle boom crane to access tight or hard-to-reach spaces means that it can reduce the need for dismantling or disassembling structures or equipment, which can save time and money on the job site.

Reduced environmental impact: The compact size of the knuckle boom crane requires less space for operation, which can reduce the environmental impact of the job site. In addition, the precise controls of the crane can help reduce the risk of damage to the surrounding environment.

Improved operator comfort: The precise controls and maneuverability of the knuckle boom crane can reduce the physical strain on the operator, making it a more comfortable and efficient working environment.

Versatility: The knuckle boom crane can be customized with a range of attachments to suit different lifting and material handling tasks. This makes it a versatile tool that can be used in a variety of industries, including construction, forestry, transportation, and marine industries.

Overall, the knuckle boom crane provides a range of advantages that make it a valuable tool for lifting and material handling tasks in a variety of industries. Its flexibility, maneuverability, and lifting capacity make it a preferred choice for many job sites.
