VDMA 35 2018 • VDMA MINING SUPPLEMENT sibly high air pressure. An oiler, situated directly at the hoist motor, is operated from the controller housing to ensure the oil flow auto- matically ceases when the hoist stops. The operating air immedi- ately initiates the motor when the hand lever is activated. This lever is spring-loaded and returns automatically to zero position when released. This forced release also serves as an emergency stop. The optional PS control is for single-handed use with emergency stop fitted as standard. It operates indirectly with a compressed air supply connected to the control valve of the motor. The control pistons of the motor are actuated by the hand control push buttons, which au- tomatically return to zero position. In the control valve of the motor, a pressure regulator protects the hoist from inadmissibly high pressure, while the integrated oiler provides the necessary lubrication. The Profi TI series hoists are also suitable for underground work- ing and operate off air pressures of 4 or 6 bar, with hydraulically op- erated units also available. Lift capacities from 250 kg up to 100 mt are available with traverse trolleys for overhead monorail operation also available for lift ratings up to 20-mt maximum capacity. A Profi TI hoist with 37-mt lifting capacity was recently used for the safe and successful handling of an assembled 1,000-m string of pipeline. This involved the connection of individual pipeline sec- tions, each 8 m long, to create a completed string weighing 30 mt, which had to be positioned within a shaft. These compact hoists offer excellent weight/load ratios, with the Profi 37 TI having an all-up weight of 880 kg (with a standard 10-m chain length) while providing an impressive 37.5-mt lifting capacity. The elimination of any electrical power supply for drive mechanisms or ancillary equipment eliminates the potential for ignition risk, while increased spark-protection features ensure the highest ATEX ratings for hazardous area operation. Hydraulically operated hoists can also be provided where a compressed air supply may not be readily available. Communications for Mine Rescue Equipment Rescue operations have been and are still one of the most challeng- ing jobs in the mining industry. During training, rescue teams of five to six members are confronted with demanding situations that push them to their limits, both physically and mentally. Some of the possible scenarios they face include bad visibility, presence of toxic and/or explosive gases, fire and smoke, rock fall and injured miners. Exceptional training, which for many includes competitions at state and national levels, prepare them well — to quickly assess the risks and to know how to deal with them. The need for a clear exchange of information is imperative in these critical circumstances, and verbal communication is usually the preferred option. A rescue team needs to be able to talk to the fresh air base, the surface, to miners and to each other. Today, traditional technology such as mining telephones is still widely used. Mine rescue teams carry their own cables for communication. They do this for good reason—it works. Unfortunately, there are certain limitations that could result in miscommunication, misunderstanding and wrong decision making. Modern communication technology has been available for years and is a common tool for every- one. This same technology is used in underground mines for a completely different challenge, however. Here, the conditions are extreme. The rescuers face harsh environmental conditions, such as humidity, water ingress, danger of collapse, risk of explosion, fire as well as excessively handled equipment. Mod- ern communication needs to support the task of a mines rescue team, not distract from it. The Dräger FPS-COM 5000 is a communi- cation device that is designed to fill that gap.
