w � ORONO COUNCIL t2EETING HELD FEBRUARY 28, 1977 Page 10 � Upon the request of Mr. Lee Primus, I inspected SKI-TONKA REPORT the Ski-Tonka ski area, which is located in (Continued) � Orono, Minnesota, to deterr,line if the equipment � met safety requirements. On February l, 1977, you furnished me with five pages of ANSI � Regulations that the City of Orono had �urnished you. The standard is American National Standard � Safety Requirements for Aerial Passenger Tramways B77. 1-1973. A copy of the five pages � are attached to this report. ! On February 3, 1977, I inspected and tested the i tow equipment to determine if the equipment met the safety requirements of the ANSI standards. � All tows were tested with the exception of #10 which was inoperable. On February 11, 1977, I � r;�et with Alan Olson, Orono City Inspector, at Ski-Tonka to jointly inspect the area and to � demonstrate to him how the tows were inspected. � At the time of my inspection, it was noted that a the ski tows were not equipped with backstop brakes as required in para. 2. 2. 5. 4. 1. The � purpose of these brakes is to prevent the ski ropes �rom being pulled backward if the ski � tow should stop for some reason. The ski tow rope was physically pulled backward to determine the amount of force required to reverse the direction of travel of the rope. In my opinion, �he tow rope would not, notwithstanding the � absence of brakes, reverse direction appreciably. Any such reversal would likely only result in � a slow reverse movement. So long as this is the case, the reverse movement would not present � a great hazard to a skier using the tow. � Para. 2. 2. 5. 4.2 of the ANSI standards requires that: � "Unless an unloaded tow operating at maximum � speed will stop in 25 feet or less an automatic brake shall be provided to assure this st�pping � distance. " � All tows. met this requirement with the exception � of tow #3 which had a stopping distance of 28 feet. Tow #3 is not equipped with an automatic brake. � The tows were then operated to determine if they � met the requirements of para. 2. 2. 5. 4. 2, ANSI Standards which requires that a saftey gate be � so located that the distance frori the stopping * device (safety gate) to the first obstruction or point of reversal of direction to the towing � outfits is 150 per cent of the distance required to stop the empty lift operating at maximum speed. All tows met this requirement with the exception of tows #3 and #6. (Continued) �
