Voith TurboHoist Retractable Guide Rail

Voith TurboHoist Retractable Guide Rail

More cost-effective, safer shaft transport – the Voith TurboHoist Retractable Guide Rail

In mines with several floor levels, the Voith TurboHoist Retractable Guide Rail enables faster passage of the conveyor cage along the floor level than systems with classic corner guiding. The unique Voith solution also greatly increases safety as there is no need to jump over the guide in the floor area.

Using a special tensioning technique, it replaces the continuous guide rail and makes it possible to load and unload the conveyor cage across the entire opening. Movement along the floor levels at conveyor cage speeds of up to 16 m/s can be achieved. Conveying 4-5% more on each floor trip results in a significant productivity increase. The guide rail, when closed, forms a continuous guide-rail run without interruptions or shoulders. The shaft signal system provides control. It is only possible to move the conveyor cages when the hub guide rail is closed.

Technical Information

Operation principle of Voith TurboHoist Retractable Guide Rail for a most cost-effective, safer shaft transport. 

Operation principle
The retractable guide rail consists of a fixed and a retractable guide-rail section. The retractable section is fastened to the bottom frame and to the transverse beams on the floor level. A hydraulic cylinder moves the retractable section (moving in and out).
The retractable section may be up to a maximum of 3.5 m in length and, when fully extended, has external dimensions identical to the fixed guide rail. As a result, when closed, it forms a continuous guide-rail run without either interruptions or shoulders. A locking device secures both the opened and closed state. To prevent uncontrolled retraction of the moving guide-rail section, the electrical control system is equipped with all the required prompts and links to the shaft signal system. The closed state is also monitored ensuring a high degree of safety. It is only possible to move the conveyor cage when the hub guide rail is closed.
