These hoists typically have lower capital costs when compared to drum hoists due to characteristic lighter, single-drum constructions and lower installed power requirements.
Koepe drums are subjected to high cyclic fatigue loads, typically reversed during every drum revolution.
Design is of necessity for infinite fatigue life. The head ropes of a Koepe hoist are subjected to cyclic variations in operating loads due to the required use of tail, or balancing ropes. For adequate rope life, the static load range should be limited to approximately 12 % of the rope breaking strength. Regular rope maintenance and replacement is essential on these hoists.
Koepe hoists are not normally favoured for depths of wind greater than 1800 m.However, for depths within the 1800 m range, very large payloads can be handled by increasing the number of head ropes.
Koepe hoists frequently find application as service hoists for men and materials using a cage and counterweight arrangement. These are often configured for use with push button cage control. Drum hoists, both single drum and double drum, are the most frequently used type of hoisting system. With multi-layer coiling the double drum hoist is frequently used for lengths of wind to 2500 meters, but can be used for lengths of wind greater than 3000 metres.
Although normally winding in balance, the range of brake torque required during emergency braking requires some form of brake control system to provide acceptable retardation levels under all winding conditions. The control of emergency braking retardation for single drum hoists is particularly problematic due to the high out of balance loads and great variation in the natural rates of retardation for different hoisting conditions. KF has extensive experience in the design of suitable brake control systems.
