FGH 40 supplies 1 million pulses per rotation for stone recognition at the bucket wheel excavator
The skip-car control mechanism utilised to date included two mechanical, geared cam limit switches that are time consuming to program. Upgrading to meet modern demands required suitable components for measuring actual values that are not only characterized by their high accuracy and functional reliability, but are also easy to program. Hübner Giessen replaced one of the geared cam limit switches with a series FG 4 K incremental encoder and an AMS 4 K type absolute encoder with integrated SSI interface. Home Case Studies FGH 40 supplies 1 million pulses per rotation for stone recognition at the bucket wheel excavator FGH 40 supplies 1 million pulses per rotation for stone recognition at the bucket wheel excavator Home Case Studies Pilger mill in tube rolling mills – hot and cold pipe detection Pilger mill in tube rolling mills – hot and cold pipe detection High-resolution encoder improves safety for excavator personnel Rapid detection of the smallest changes to rotation speed when excavating stone Avoids mechanical damage to the power train Robust design features high resistance to shock and vibration The operator cabin of the bucket wheel excavator is located at the end of the boom. Challenges A seam of lignite can be as deep as 100 m below the surface of the earth. In the majority of cases bucket wheel excavators are used to recover the lignite. The so-called stone excavation masks a high risk. The bucket wheel can become blocked if a tooth of a bucket comes up against a pocket of firmly entrenched stone. The increased load moment can result in the rotation speed of the bucket wheel dropping within a very short period of time. The blockage simultaneously causes the bucket wheel boom to lower. The entire construction of the bucket wheel excavator performs a dipping motion in the opposite direction to the rotary movement of the bucket wheel. This results in a further drop in the rotary speed of the bucket wheel. Personnel could be exposed to a hazardous situation if the tooth of the bucket wheel slips from the stone and causes the bucket wheel boom to swing upwards. The high-resolution encoder FGH 40 detects even the smallest changes of rotation speed very rapidly. Solution The high-resolution incremental encoder FGH 40 is equipped with a pulse disk and optical scanning technology to provide up to 1 million pulses per rotation. Utilising this encoder ensures it is possible to stop the bucket wheel within a rotational movement of less than 2° should the speed of the bucket wheel drop by just 0.5 rpm – before damage can occur to the power train. As is the case with all Hübner devices the FGH 40 is designed for use in heavy duty applications. Suitable for temperatures ranging from -25 °C to +85 °C it is also highly resistant to shock and vibration. Standard degrees of protection to IP66 and IP67 ensure they can be used in both wet and dust-laden environments. Above all, the safety of excavator personnel is significantly improved by the new FGH 40 encoder and the considerably faster reaction time for stone recognition.

Switching accuracy at the crane hoist by compact incremental encoder with electronic over speed switch
The EGS series of electronic overspeed switches from Johannes Huber Giessen are the ideal solution for heavy -duty applications that demand the highest levels of precision and reliability. These devices make it possible to monitor both overspeeds and underspeeds across the complete speed range with utmost precision. Home Case Studies Significantly higher switching accuracy at the crane hoist thanks to compact incremental encoder with additional electronic overspeed switch Higher switching accuracy at the crane hoist by compact incremental encoder with additional electronic overspeed switch Home Case Studies Pilger mill in tube rolling mills – hot and cold pipe detection Pilger mill in tube rolling mills – hot and cold pipe detection Modern replacement solution for mechanical overspeed switches Compact design with an incremental output and electronic overspeed switch Pre-programmed switching speed Easy mechanical and electrical exchangeability Before: Tacho generator with attached mechanical overspeed switch for speed measurement and monitoring at the hoist of a RMG crane. Challenges A tacho generator and an additionally attached mechanical overspeed switch are responsible for speed measurements and overspeed monitoring at the hoist. Due to its design the mechanical overspeed switch has a switching tolerance of ± 75 rpm, which leads to inaccuracy at the desired switching point. Moreover, the mechanical overspeed switch only reacts to speeds of 700 rpm and above. The signal quality of the tacho generator does not o er the precision required in today’s world. The customer wished for a replacement solution that corresponds to current state of the art technology. Products and Accessories Speed feedback for auxiliary drives Couplings Adapter Shaft After: Significant more precise speed monitoring by the incremental encoder FG 2 with integrated electronic overspeed switch. Solution Based on the experience gained from previous modernization projects the implemented solution saw the installation of an incremental encoder FG 2 with an integrated electronic overspeed switch (option S). In addition to the incremental position value this compact encoder solution o ers a switching speed set ex works. The electronic overspeed switch provides signifi cantly more accurate overspeed monitoring. The switching speed of 2550 rpm was adopted from the previous solution 1:1. Not only is the overall length now distinctly shorter, this solution requires no changes to the existing mechanical interface. The entire conversion was implemented quickly and easily.

The raw steel blocks, each weighing a few tons are heated up first in a round oven at a temperature of 1300 °C. After descaling of the surface, the steel block is prepunched in a hole press with a strength from a converted 2000 t. In the next sloping rolling mill the growing pipe rotates between two rollers that are positioned at an angle to each other. The punching is widened to the size of the mandrel diameter. Previous solution / Competitor product N/A Solution The sensor that was installed at this application is the HMD OKA 2038.38 G with tube OL 19. The signal of the infrared sensors controls the movement of centering device and abutment. The point of view is restricted by the tube and prevents disturbances by steam in the cooling phase. An optimum adaptation to the operating conditions is given due to the adjustable response temperature. The HMD with self-learning response temperature (Auto-Teach function) is suited to continually changing conditions. The compact sensor with a stainless steel housing can withstand surrounding temperatures of up to 75° C. The use of a cooling jacket raises this up to 200° C. Alternatively sensors with fibre optic cables are available which permit an application at ambient temperatures up to 600° C without cooling.

Replacing mechanical cam limit switches on cranes without PLC
The ERC 40 Series of electronic position switches from Johannes Hubner Giessen are the ideal solution for heavy-duty applications demanding the highest level of precision, user friendliness and reliability. These devices make it possible to monitor both position and limit switching point across the complete position range with utmost precision. The ERC 40 Series is reliable, comfortable, flexible and safe. Home Case Studies Replacing mechanical cam limit switches on cranes without PLC Replacing mechanical cam limit switches on cranes without PLC Home Case Studies Pilger mill in tube rolling mills – hot and cold pipe detection Pilger mill in tube rolling mills – hot and cold pipe detection Position monitoring – also without PLC Replacement for discontinued cam limit switches Higher positioning accuracy Suitable for 1:1 replacement Before: Mechanical cam limit switch. Challenges Some mechanical cam limit switches deployed in cranes or in conjunction with an obsolete PLC have either been discontinued or the devices cannot be replaced for other reasons. In that case a solution is required that updates the position switches on the crane to a state-of-the-art technology – without extra construction effort. After: The electronic position switch ERC 40 from Hübner Giessen as a 1:1 replacement solution. Solution With the electronic position switch ERC 40 from Hübner Giessen the user is now able to program the high precison switching points via software. The programming is easy and quick. At the same time, the values remain permanently in the system and cannot be affected by shock and vibration. Other advantages are: Real switches up to 230 V and 0.5 A – existing cables can be kept most of the time Use the latest technology without converting to a (new) PLC at the same time The ERC 40 offers a suitable replacement system for many cranes and installation situations. This enables more flexibility, higher accuracy and less spare parts.
