TROLLEYS 27 General Railtechniek developed a complete range of standard wheelsets to which a specific item such as a bolt, a hook etc... fits according the application. All wheelsets are mounted on ball-bearings. The wheels are working independently and are mounted two by two (bogie arrangement). Depending on the application there is the choice between 2-wheeled, 4-wheeled or 8-wheeled trolleys. All trolleys can rotate on their vertical axis (except series ... .550). The trolleys are also provided with vertical guides in order to avoid the overturning and to assure a perfect guidance during the translation. The standard trolleys are fitted for temperatures of maximum 100 °C. In case of working conditions up to 150 °C or up to 300 °C, the trolleys are mounted on special high temperature ball bearings. The code of the trolleys changes according to the working conditions : e.g. : Up to 100 °C Up to 150 °C Up to 300 °C Ref. 244 010/1 243 510/1 243 010/1 Carrying capacity of the trolleys In the tables the maximum carrying capacity ‘F’ is indicated. In order to calculate the carrying capacity F, the real net load has to be increased with the operating coefficient and the temperature coefficient ‘y’. F = Fn xØx y Remark: The maximum admissible carrying capacity “F” of the trolleys is indicated in the tables with operating coefficientØ=1 and temperature coefficient y =1. Note: The maximum temperature for trolleys with nylon wheels is 80 °C. Finishing: electro galvanized Table:1 OPERATING COEFFICIENT Ø Kind of operating Coefficient Ø I. Very moderate use, no shock or impact load (e.g. the daily transfer of a load along some meters) Il. Normal use, very light shock or impact load (e.g. automatic equal motion with a speed of max. 10 m/min., motion time of the trolleys up to 20%max.) III. Frequent use, light shock or impact load (e.g. manual motion with unequal speed, motion time of the hangers 20 to 50 %). IV. Very frequent use, shock or impact load (e.g. continuous working automatic installations, motion time of the hangers 50 to 100% 1 1.21 1.33 2 Table:2 TEMPERATURE COEFFICIENT y Temperature Temperature coefficient y 15 à 100 à 150 °C à 200 °C à 225 °C à 250 °C à 275 °C à 300 °C °C = 1 = 1.05 = 1.15 = 1.25 = 1.35 = 1.50 = 1.70
