Thoughtful

Safety and ergonomics play a major role

T‌he operation of large machines is often associated with an increased risk potential. This also applies to crushing and screening plants, where large lumps of rock are processed into small grain sizes using immense forces. That is why the protection of people is a top priority at KLEEMANN. However, safety must not hinder the operator, but must be integrated into the work process without being noticed. The complexity of modern plants is increasing, at the same time the KLEEMANN development team makes sure that operation and maintenance remain as simple as possible – without long training.

 

The interface between man and machine is the control system. The entire PRO line and the MOBIREX MR 130 Z EVO2 impact crusher can be conveniently operated via the intuitive SPECTIVE control concept. The 12-inch touch panel simplifies work as all functions are visible at a glance and clear symbols show the way. The user interface is insensitive to dust and splash water and can be read perfectly under difficult lighting conditions. Simple menu navigation ensures that only what is currently needed is displayed on each page. This concept makes it easy to use the crusher correctly and to make full use of its functions.

 

In daily use, however, not only a simple control is important, but also good accessibility to the machine. As a result of a well thought-out machine design, all service-relevant points are easily accessible. For example, the MOBICONE MCO 11 PRO cone crusher can be refuelled conveniently from the ground, and the impact crushers MOBIREX MR 110 and 130 Z EVO2 have a separate platform for easy replacement of the pre-screen linings. Other service work on the machine can also be carried out quickly and conveniently thanks to the good accessibility. 

 

When changing the impact bars on the mobile impact crusher or releasing bridges, the EUROTEST certified “Lock & Turn” system ensures maximum safety. Here, special keys are used in combination with the machine control system, which only allow working in hazardous areas if they are secured. Only then can the operator open maintenance flaps or move and exchange components. If the operator wants to work at a different location, the keys must be removed, which automatically locks the previously worked area. A real highlight in terms of safety and comfort is the rotor turning device in this system. It allows the crusher’s rotor to be manually turned and locked in any position from the outside via a gearbox. The replacement of impact bars as well as the elimination of bridging can thus be carried out more safely.

 

The new option package for noise reduction ensures comfortable and safe working close to the impact crusher. Noise protection flaps are fitted at the side, at the height of the engine, to divert the sound upwards. These are folded down for transport to the plant and thus have no influence on the transport width. In addition, the unit floor is sealed soundproof. This reduces the perceived volume by six decibels. For the human ear, a reduction of three decibels is already half the noise perception. This not only allows the operator to work in a much smaller area around the machine, but also protects the environment and allows the units to be used in urban areas. For this ­solution ­KLEEMANN was awarded the Environmental Technology Prize of Baden-Württemberg in 2019.
