Articulated knuckle boom cranes are just as the name implies. They have 2-3 pivots (depending on type, brand, etc) that allow the boom to bend. Knuckle boom cranes use the boom to pick and place, as opposed to "stiff boom" cranes, that use the boom as a fulcrum and a rope style winch that does the lifting.
Knuckle boom cranes are to be respected and proper training is essential and at the Crane Instructor we can help train your operators to become very skilled on all knuckle boom cranes that lift LESS than 15, 000 pounds in Alberta.

What is an excavator?
it is a machine used to dig the earth, it can also be used to lift thing such as a crane would, but only as high as the boom of the excavator will rise and the weight is dependant on the size of the excavator.
What is the major difference between a friction crane and a hydraulic crane?
A friction crane is an older model like an American 9210 who's boom controls are gear/ clutch driven. Engaging the clutch and throwing the gears requires a very stout frame and they typically have much stiffer booms and can tolerate a lot more abuse.... They are good for rough lifting operations like pulling pile or pile driving. Hydraulic cranes are there modern counterparts who's boom is controlled by hydraulic pistons which have a much lighter, more delicate touch to the controls and are much better in "heavy lift" operations where you need precision movement.
What is crane engine?
An engine specifically designed or adapted to Cranes. One such model is a Big Cummins Diesel that has twelve cylinders and is rated at 635 maybe 685 HP and is available standard on certain marques and models of heavy-duty crane. with a 200 foot boom, l50 ton lifts are well within the duty cycle!

Which way do boom pins face on crane?
The importance of which way boom pins face on a crane is less important then how they are removed. In 1997, a crane mechanic faced fatal injuries when a crane fell on him, because he removed the crane pins with a hammer.
What crane device limits the angle of the boom at its highest position?
boom stop
What is a boom truck and what does it do?
A boom truck is a long flatbed truck with a crane attached. They are often used for reaching inaccessible areas and lifting heavy objects. In some respects, it is a type of crane.
How do you calculate the crane boom lifting capacity?
The crane boom lifting capacity is determined by the base weight, the angle of incline and the length of the boom. Cranes are given a maximum lifting rating. Weights are graphed showing the maximum under each variable.
What is boom dog in crane?
1. From the meaning of the words, I was guessing that a boom dog is a mechanism that keeps the crane's boom in one position, preventing it from accidentally moving around. 2. However, a friend then mentioned that a boom dog is something that keeps the boom going in the up direction only.

Where online can a person find more information about 'knuckle boom' cranes?
A person can find more information online about 'knuckle boom' cranes through Wikipedia or via the official 'Knuckle Boom' site. A Knuckle Boom crane appears similar to a standard crane, except that the boom articulates at the 'knuckle' near the middle, letting it fold back like a finger. This provide a compact size of storage and maneuvering.
What is crane boom luffing?

What is the amusement ride based in part on a rotating crane boom its Italian methinks ride is an extreme ride and is engineered much like a crane with struts and longerons on the boom bulkheads etc h?
The Ride is known as the Booster. The structure is very similar to a Crane Boom and indeed Crane technology was used in its design. I heard fronm operators that she is rated for a maximum (Line Speed) of 70 M/P/H/ simlar to a hammerhead crane. The ride was featured a the Meadowlands State Fair in 2004 and probably mnor recently.

How do calculate working radius of a crane?
calculate radius of crane: The radius is always measured from the centre of rotation and is the radius measured after the boom deflects forward when under load.
