FAQ

Q: What size of knuckleboom crane do I need?

A: This depends on the type of jobs you will be using the crane for. For example, there are small knuckle boom truck cranes that can be used to lift loads of less than one ton while there are very large knuckle booms which have a 60 ton lift capacity. When you are searching for an articulating crane, let us know your lifting requirements and we will find the right crane for you

Q: What is the outreach of a good knuckleboom?

A: Again, this depends on your lifting requirements. For example, some have an outreach of only a few meters, yet others can reach over 30 meters. These are just two examples; there are varying outreach distances for different cranes.

Q: How do I control the knuckle boom crane?

A: There are many options for the operator, including the remote/wireless control, top seat control, stand up control, and ground control.

Q: What is the difference between hydraulic and electro hydraulic?

A: Electro-mechanical solutions only use power when moving the load. In comparison hydraulic systems generally have to maintain pressure levels to either maintain position when holding a load or to ensure that the system can respond when required.

Q: What are the design considerations for a hydraulic grabber?

A: When selecting a hydraulic gripper, it is important to consider the following: 1. Part weight and size to be lifted 2. Part material 3. Clearance issues around the part that could interfere with the gripping part 4.
