Reel servant
A reel servant , even reel puller or Haspler called, is a miner , who in the early mining as transport workers in the well production worked.
activities
The work of the Mountain servant was to the ores and mountains for over days to promote and the material from above ground into the pit. He had to do this with a hand reel. The miner's work was seen as the least valuable, which is why he received the lowest wages of all miners. A coiler servant in the Schwaz mountain area received a weekly wage of 42 kreuzers.
Since this reel was attached to a scaffolding or a platform above the shaft , the reel worker had to go to the scaffolding on which the reel stood to operate the manual reel. It was necessary to position the reel on a scaffolding so that the hoisting rope was guided vertically into the shaft. In order to operate the reel, the reel servant had to set the reel in rotary motion with the muscle strength of his arms using or with the support of his body weight. To do this, he took hold of the reel crank on the so-called capstan and pushed the crank down so that the reel started to swing. Due to the different height of the reel horn during the turning movement, it was not able to optimally apply its force to the reel. Also, he could not use his strength the full shift continuously, but needed short breaks in between. These breaks were around half of the funding period. The effective working time during a 12-hour shift was therefore around 8 hours.
Delivery rate
The coiler servant always worked in thought . Previous calculations were used to determine how many coiler workers were required to convey a certain number of buckets from a certain depth during a shift . The wages for the attacker and any other auxiliary workers required were also given in the calculations. There were special calculation bases for this. There were differences in the delivery rate in the individual mining districts. In the county of Mark, the extraction rate of the coiler workers, which they produced from a 14.9 pound deep seigeren shaft with an average of 2.7 men, was 156 bushels per shift. For this promotion, 104 vessels with 1.5 bushels each had to be promoted. In the Thuringian lignite mines, 3 reel workers each had to extract 80 tons of lignite with 4 bushels each from a 20-pound deep shaft during the 12-hour shift . In the Saxon Ore Mountains, the production quantity was 120 buckets of ore during an 8-hour shift from a depth of 20 pods. From the same depth in the Kammsdorf ore mines, the coiler workers had to extract 32 tons of iron ore with 4 bushels each.
Performance optimization
Tests and calculations were made to optimize the conveying capacity of the reel workers. The realization was gained that, in addition to the strength of the reel workers, it was also important how well he could let this force act on the reel. For this purpose, the optimum height for operating the reel crank was determined. The size of the so-called bug, i.e. the length of the crank arm, is also decisive for the optimal use of force. The decisive factor is how far the reel servant has to stretch his arms when turning the crank. The optimal length and thickness of the handle was determined so that the reel could comfortably grasp the handle with both hands. The two-man reel turned out to be the best type of reel. With the four-man reel, the four reel workers could not use their strength optimally, so that only the force of two reel men acted on the reel.
