Derail and/or bumper blocks shall be provided on spur railroad tracks where a rolling car could contact other cars being worked, enter a building, work or traffic area. (5) Positive protection shall be provided to prevent railroad cars from being moved while dockboards or bridge plates are in position. (7) Brakes shall be set and wheel blocks shall be in place to prevent movement of trucks, trailers, or railroad cars while loading or unloading. (4) Positive protection shall be provided to prevent railroad cars from being moved while dockboards or bridge plates are in position. (2) Wheel stops or other recognized positive protection shall be provided to prevent railroad cars from moving during loading or unloading operations. (iii) While cars are on sidetrack for loading or unloading, the wheels at both ends shall be blocked on the rails. (v) Brakes shall be set and wheels blocked on all cars being unloaded. (iv) The track of a tank car siding shall be substantially level.

Signs shall be of metal or other suilable material, at least 12 by 15 inches in size and bear the words ‘’STOP-Tank Car Connected” or ‘’STOP-Men at Work” the word, “STOP,’ being in letters at least 4 inches high and the other words in letters at least 2 inches high. (iii) Caution signs shall be so placed on the track or car as to give necessary warning to persons approaching the car from open end or ends of siding and shall be left up until after the car is unloaded and disconnected from discharge connections. (vi) A derail shall be used to prevent movement of other rail equipment into cars where persons are working. Where equipment is not provided with hand brakes, rail damping chocks shall be used. (V) Flatcars and all other cars shall be chocked during unloading. (4) Handling pulpwood from flatcars and all other railway cars. Slack in mechanical car brakes can be enough to allow a wheel to move forward a few inches and dislodge a dock board or strain a hose line Loading Pulp and Paper Railcars Liquid pouring into a tank car or a forklift moving back and forth in a boxcar create dynamic forces which can overcome the holding power of the brakes. Loading freight cars increases the strain on the car brakes. This is why moving heavy loads by rail is so efficient! But at the same time, all this mass, so easily moved, needs to be securely blocked while the car is being worked. In fact, the contact area of each wheel on the rail is smaller that the size of a dime. Thanks to roller bearings, freight car wheels offer very little resistance to movement. OSHA mandates the use of wheel chocks in addition to car brakes wherever rail cars are being worked, loaded or unloaded.Ī gust of wind is enough to cause a 260,000 pound freight car to start rolling. If cars are uncoupled to be worked separately, brake and chock each car. Move cars forward and repeat the braking and chocking procedure. When the first car is ready to be moved, remove the chocks and release the brakes on both cars. It may be necessary to brake and chock several cars behind the car to be worked depending on your operating conditions. On flat track, where a line of rail cars remain coupled together, and are moved forward progressively to be loaded/unloaded: Brake and chock the car to be worked (chock both ends of the car). On uneven track if the car tends to roll in one direction, single chocks on the foremost wheel of both wheel sets may be sufficient. Railcar on Slope or Hillĭo not use wheel chocks. Square fenders can be provided in specified lengths and the ends can be bevelled.Idle Railcar on Storage Track and Railcar Being Workedĭouble Chocks on each end of the car provide two-chock blocking against movement in either direction. Square fenders can also be produced vulcanised in a specific radius to ensure that it fits properly around a bow or stern of a ship. The fenders are finished in accordance with your requirements and drawings. The mounting holes required are made through the side or through the top and bottom of the fender. Square fenders can be mounted in several ways by means of bolts and/or strips. Square fenders with a smaller dimension can be produced in very long lengths and in other colours (non-marking). Customer specific sizes and designs can also be produced with short lead times. When compared to D- fenders, square fenders are used when a more rigid and stronger bumper is required for use in more severe conditions.FenderTec produces square fenders in a standard range and most common sizes are kept in stock and can be delivered at short notice. bumper blocks help keep parking lots ordered and prevent vehicles from pulling too far into a parking space, lowering the risk of parking vehicles injuring pedestrians walking through the lot. Concrete bumper blocks installed in your parking lot add to the safety of your commercial property. The production takes place by means of extrusion. They improve the safety of your parking lot.

Square fenders are produced in various designs and sizes and they can be used for a wide range of purposes.
