Project Description

Jib Arm for loading and unloading Slabs in Closed Containers.

At HERSEN we manufacture accessories for cranes such as this arm for loading and unloading boards in closed containers. This class of load arms is used in those occasions in which the load has been carried out with a central stand and bundles (or packages of boards with packaging) have not been used.


Generally, the cargo that is usually transported are boards that are less than 1.7 meters high, such as quartz or artificial materials. In this way, this arm can also load bundles as long as they are not taller than 1.7 meters.

In this model, the load is below the arm that is introduced into the container.

In general, bundles are not used, a trestle is placed in the center and loaded directly on the trestle. For example, with the 5tn model, 26 2cm boards can be loaded in each cycle. In just 4 cycles, the container is loaded. It is very fast and requires very few personnel.

Types and characteristics of the arm for loading and unloading of boards

One of the great advantages of this loading arm model is that it allows you to get as close as possible to the sides of the container, this makes unloading the material much easier.

The loading arm has an empty weight (when it is not loaded) and once it is loaded the sum of both (empty weight + load) gives us a total weight. The crane where the loading arm is installed must have the capacity to lift this total load.

The 5tn crane is one of the most widely used in marble workshops. When this is the case, to lift up to boards up to a weight of 3.5 tonnes it requires that the loading arm weigh less than 1.5 tonnes to be able to be used in this type of 5 tonne cranes. For this reason, two types of construction are made: standard (model B) and light (model BL)

One of the main differences between one model and another is that the standard construction weighs more empty than the light one.

In this way, with the BL model it is possible to load / unload boards up to a weight of 3.5 tonnes with a 5 ton crane. On the other hand, with the B model, up to 1.6tn can only be loaded when using this crane capacity. To reach 3.5tn with the B model, it must be installed on a 7tn crane.

This type of loading arms, which are used as a crane accessory, can be manufactured with different capacities and measures for both the B model and the HERSEN BL model, although the most used and demanded are these two models:

Arm for loading and unloading Model B

Load capacity: 3.5 Tn

Total length *: 7.5 m

Empty weight: 3.4 Tn

Ref. 50182

Arm for loading and unloading Model BL

Load capacity: 3.5 Tn

Total length: 9.6 m

Empty weight: 1.5 Tn

Ref. 50184

(*) The total length refers to the upper part. As for the lower length, that is, the part that goes into the container, it is the same in both models.
