Types of Jib Cranes
Over-braced Profile Jib Arms
This is the most free-running type of jib arm and therefore the easiest to operate. It can improve production times considerably.
Features:
- SWL: 25 to 2000kg
- Arm length: up to 6m
- Lightweight and easy to use
- Electrical festoon cable supply – runs inside the arm track, before the load trolley.
Under-braced I-beam Jib Arms
This type of jib arm offers the lowest headroom solution and is perfect for situations where the lifting height is limited.
Features:
- SWL: 25 to 2000kg
- Arm length: up to 6m
- Electrical festoon cable supply – usually runs along the arm beam, before the load trolley. Alternatively it can be fed by a parallel track, which won’t limit the jib travel.
Over-braced I-beam Jib Arms
This type of jib arm is the best solution to facilitate powered travel along the arm.
Features:
- SWL: 25 to 2000kg
- Arm length: up to 6m
- Electrical festoon cable supply – usually runs along the arm beam, before the load trolley. Alternatively it can be fed by a parallel track, which won’t limit the jib travel.
Articulated/Knuckle Jib Arms
This type of jib arm has a second pivot point along the arm and a fixed suspension point at the end. The second pivot enables the jib arm to lift and rotate within a 360° arc. The footprint of the arc is limited in some areas by the way the arm articulates around the central joint, but it does allow the arm to operate in a way that will enable it to miss obstacles that an ordinary jib might collide with.
Features:
- SWL: 25 to 500kg
- Arm length: up to 4m
- Electrical cable supply – usually runs along the arm
