A 50 ton knuckle boom crane is a type of crane design to lift and move heavy loads. Typically weighs up to 50 tons (45 metric tons). It has an articulate arm, which is an articulated crane arm that is make up of multiple parts. Can be fold and extended to reach greater distances.
XJCM rough terrain crane consists of special crane chassis and lifting operation device. Including power system, transmission system, suspension system, steering system, braking system, lifting, mechanism, booster mechanism, hydraulic system. and electrical systems. All XJCM rough terrain crane have Front-wheel steering,
rear-wheel steering ,four-wheel steering and crab steering,all-wheel drive, off-road performance ,suitable for off-highway travel.
Working with fully extended outriggers, working with half extended outriggers, working with fully retracted outriggers, and working with outriggers are not resistant to traffic loads. The crane has good passability, dynamic performance and maneuverability. It can work in all directions and go with the crane. There are no outriggers.
XJCM RT 50 cranes are widely use in heavy-duty lifting operations, short-distance transfer, and lifting operations in narrow places. It is usually use in construction sites, open-air oil fields, warehouses, freight yards, logistics bases and other places.
Q: What is the maximum lifting capacity of a 50 ton knuckle boom crane?
A: A 50 ton knuckle boom crane can lift up to 50 tons or 45 metric tons.
Q: What are some applications of a 50 ton knuckle boom crane?
A: 50 ton knuckle jib cranes are commonly use in the construction, mining and shipping industries. Used to complete various tasks. Examples include loading and unloading cargo, moving equipment and materials, and building large structures.
Q: How is the knuckle boom different from a straight boom?
A: The folding arm consists of multiple parts that can be fold and extend. Whereas the straight arm is a section that can only be extend in a straight line.
Q: What is the advantage of having stabilizing legs or outriggers on a knuckle boom crane?
A: Stabilizing legs or outriggers provide additional support and balance during lifting operations, which improves safety and stability.
Q: Can a 50 ton knuckle boom crane be operate remotely?
A: Certain models of 50 ton knuckle boom cranes may have a wireless remote control option. Allows the crane to be operate from a distance.
