Jumbo Loader

Boersema supplied a unique bulk truck loading installation:

The Jumbo Loader, type JBL-500-FC.

This Jumbo Loader is one of the largest mobile loading installations of its kind in Europe.

With this installation, practically all products can be loaded from a big bag into a bulk truck. For this purpose, the Jumbo Loader is equipped with a:

  • Mobile frame, on which the pipe screw conveyor, extraction filter, loading bellows, compressor and switch box are mounted. The mobile frame is clamped during the loading, with the result that greater stability is obtained.
  • Pipe screw conveyor for transporting the product from the pouring funnel via the loading bellows to the bulk truck. The pipe screw conveyor is equipped with hinged covers on the top. Via these covers, it is possible to internally clean the pipe screw conveyor with water. Installed on the inlet of the pipe screw conveyor is a pouring funnel, into which the big bags are emptied. The pouring funnel is equipped with a vibrator to facilitate better emptying of the big bags.
  • Extraction filter, which is connected to the pouring funnel for dust-free emptying from the big bags.
  • Loading bellows type ZAZ 60-30 is mounted to the outlet of the pipe screw conveyor. This type of loading bellows is the most complete one in our range and is equipped with a built-on electrical hoist, an extraction fan, an inbuilt filter and an under-spout with patented spreader head. With the patented spreader head, it is possible to fill a bulk truck up to approx. 90%, with fewer manholes than usual.
  • Compressor with storage tank for cleaning the filter elements with compressed air.
  • Switch box for the operation of the pipe screw conveyor, the extraction filter, the bellows bag, the compressor and the hoisting of the pipe screw conveyor. Mounted in the switch box are frequency inverters with which the speeds of the pipe screw conveyor and the extraction fan can be controlled. The consequence of this is that the loading capacity can be altered from 75 m³/hour to a maximum of 150 m³/hour.
