The articulated jib crane – large working radius and combination with a wide range of load suspensions

The articulated jib crane is a special design of jib crane with an additional joint in the jib. The joint allows the radius of the jib to be reduced, for example to avoid obstacles and to work behind the crane column to a limited extent, as shown in the following sketch. The grey area of the drawing shows the large working range of the jib crane:

The position of the joint can be adjusted to specific working areas, so that an optimal and smooth operation is possible. In contrast to the jib crane with trolley, the load pick-up of the articulated jib crane is always at the end of the outer boom. This is particularly advantageous when a rope hoist or a rope balancer is used. The drive unit of the balancer is then mounted on the outer arm or near the column and the rope is guided to the end of the outer arm via rollers. This arrangement saves the operator from having to move the mass of the cable pull along with it and reduces the force required to move the articulated arm accordingly. By eliminating the lifting device, the available hook height is increased by the dimension of the lifting device, which is particularly advantageous in low rooms, thus enabling the use of a lifting aid.

With its combination of the ezzFLOWsmart balancer and the ezzLINKeco articulated jib crane, Best Handling Technology offers a proven compact handling system.
The ezzFLOWsmart is electrically operated and ideally suited for handling, mounting or joining sensitive products in the exact position. This intuitive handling system adapts perfectly to the needs of the user and his activity.

The ezzFLOWsmart’s main areas of application are therefore in the field of handling when joining and assembling components, e.g. when assembling machines, apparatus and vehicles, component and subassembly assembly, loading machine tools, as well as assembly aids for motors, gears and couplings and tool changes. Furthermore in many other, mostly precise handling tasks.

Since the balancer holds the workpiece in suspension, the operator can focus his full concentration on his work and the precision by guiding the workpiece directly with his two hands.
Fine tuning of the balancer, such as programming of delay times, returns and speeds, can be carried out directly on site on the display. No need to connect a PC, no waiting times etc., so the ezzFLOWsmart offers maximum flexibility.
In addition, there are no jerky movements during the lifting and lowering process and no shock load. Vibration-free operation is also guaranteed.

The programming of the ezzFLOWsmart’s electrical control system is developed and produced in Germany. This allows maximum flexibility for customer-specific adaptations. A wide range of programming options allow integration into the higher-level control system of the production line and precise adaptation to the handling task.

All versions of the ezzFLOW are equipped with the optimized load handling devices according to customer requirements. The right load handling attachment (LAM) is of decisive importance to ensure that the corresponding components can be picked up safely, intuitively and quickly. If, for example, products with smooth surfaces are to be moved, load handling with vacuum suction cups is a good idea. One or more suction cups are optimally arranged for lifting the load.

Electric and pneumatically driven systems are available for vacuum generation. In addition to the resources available to the user, energy costs are a selection criterion.
Pneumatic vacuum generators are only activated during the lifting process and only then do they consume compressed air. The energy costs for electric vacuum pumps are generally lower, but they must be operated continuously. The correct choice of vacuum generation therefore depends on the intended use.
Fig. 4 shows a vacuum load pick-up that is operated with an electric vacuum pump positioned in the area of the crane jib. Figure 5 shows a pneumatically operated vacuum suction cup. The vacuum generation is integrated in the suction cup; only a compressed air connection is required by the customer.

The recommendation of the optimum handling system should be worked out by our specialists, taking into account the application, who will take into account all local conditions when selecting the correct handling system.
