AG Cranes specialise in the supply, installation and load testing of Jib Cranes. Swing Jibs or Pillar Jibs as they are oftern referred to are the staple of our product range, giving low cost and effective solutions to every day material handling issue's found in the work place. Jib cranes cover a wide range of capacity's, starting as low as 80kg and ranging upto 10000kg and above, although the most popular capacities seem to be from 250kg upto 2000kg.
The pillar jib crane is a simple yet effective piece of equipment giving the operator total control of the load within the slewing arc, the general slewing arc of a swing jib crane is 290 degrees, this is true of most manually operated makes of jib crane, it is possible to get a full 360 degree arc of coverage but this is usually on powered slew's only.
There are two main types of pillar jib crane, under-braced and overbraced, the arm on the later is usually made from channel profile with a bracing welded from the top of the pillar to the end of the arm to give support, the hoist and cable trolleys would then travel inside the profile length. The under-braced type is supported by a large gusset on the underneath of the arm and can be a channel profile as decribed above or an I-beam section as shown in the picture above. The under-braced option is advantageous because of the greater hook height afforded by the height of the arm, this can be useful for gaining maximum hook path in lower headroom environments.
One of the most comonally asked questions about pillar jib cranes is regarding the installation and how best to fix them to the floor, we carry out many jib crane installations nationally and will always use one of two methods, the first of which is resin anchors and the second is foundation anchor frames, both methods are explained more clearley below:-
