Pocketlift - Vertical Conveying in a Pocket

POCKETLIFT Type III: Crossbar and pocket

The Pocketlift system is the most recent innovation in the field of steep incline and vertical conveying for the bulk materials handling industry.

Based on the Flexowell technology and the high capacity bucket elevator, the Pocketlift system was developed for deep shaft underground applications in the mining and tunneling industry and achieves lifting heights of up to 800 m (2625 ft).

Best choice for continuous conveying

Pocketlift technology is offering mining engineers and operators the possibility of achieving a continuous mass flow over a lift height of several hundred meters, which brings with it a number of additional benefits, such as:

  • Reduced energy consumption
  • Small shaft diameter
  • Quick installation
  • Low maintenance costs
  • No underground bunker system required
  • Lightweight steel structure for feeding section and headframe
  • Environmentally friendly
  • No mechanical parts in the vertical shaft

Technical details

With Pocketlift, power transfer is achieved by means of two narrow steel cord belts connected together with rigid triangular cross bars. The material to be conveyed is fed into the fabric reinforced rubber pockets, which are bolted to the center of the cross bars. These bars also have a guiding function. All three elements can be mounted and removed separately and can be installed on site.


The standard Pocketlift Type III achieves capacities of up to 1500 m3/h (883 cu.ft/min) and lift heights of up to 800 m (2625 ft), while the new generation Pocketlift Type II was developed for high capacities up to as much as 4000 m3/h (2354 cu.ft/min). Different pocket widths for both systems enable them to be tailored to precisely meet customer requirements.

As the main fields of application are underground mining and tunneling, it is mandatory that we hold the safety approval from all major mine inspectorates and standards, such as MSHA and ISO 340/EN 20340.

Oil and fat-resistant and heat-resistant rubber compounds are available for high capacity silo feeding in the food and cement industry.
