| Waggon End Tippler | ||
| Waggon end tipplers require unloading flaps at the waggon and walls. Unloading is made, with opened end flap, by tipping in the longitudinal direction. During this procedure the waggon buffers come to rest on to the extended buffer blocks of the platform. Both unilaterally and bilaterally operating end tipplers have been built. Unilaterally acting end tipplers imply that the waggon is introduced in such a way that the brakeman's cabin at the waggon is on the opposite end of the direction of tipping. Bilaterally acting waggon tipplers allow for the unloading of waggons regardless of the position of the brakeman's cabin. Slewing end tipplers allow for this too and offer furthermore the advantage that material can be discharged into several sorting hoppers that are arranged around the platform. | ||
| Waggon and Truck Unloading Systems | ||
| Tipplers perform the task of unloading bulk material from waggons and road trucks. For this purpose different tippler types have been developed including rotary tipplers, side tipplers and end tipplers to suit a range of conditions, client requirements and modes of transport. More and more waggons are equipped with rotary centre couplings which allow the use of rotary tipplers. This saves time by eliminating time consuming coupling and uncoupling procedures and consequently considerably increases the capacity which can be obtained. The design of waggon tipplers generally allows the locomotive to pass through, but the positioning of waggons should rather be done using modern train haulage and marshalling systems which have been developed by ThyssenKrupp Fördertechnik. These are more economical and also offer greater efficiency. The provisions for environmental protection gain an ever increasing importance and that is why ThyssenKrupp-dumper plants can be further equipped with all necessary facilities for de-dusting or dust suppression. We recommend always contacting us when you have a case of need, as we can assist you in selecting the tippler system that suits best your particular requirements. | ||
| Travelling and Slewing Waggon Tippler | ||
| The waggon is first lifted up to an angle of 30°, then slewed through an angle of 90° over the underground bunker, then lifted up to 60° and unloaded. Hourly unloading capacity is 12 waggons. These machines can serve, from a through rail track, whole series of unloading stations. The slewing platform is mounted onto two or three axes standard gauge bogies. Via introducing tongues the waggon is drawn onto the platform. The latter is slewed and tipped. The highest tipping position is with 60°. Following unloading the waggon can run off in both directions. Preference is given to the use of the system with overhead and underground bunker arrangement. | ||
| Side Discharge Waggon Tippler | ||
| Side discharge waggon tipplers are given preference where, as a result of a high water table, the unloading hopper as well as the discharge devices can be arranged underground in shallow limits only. Unloading is achieved by a 150° to 160°turning motion. Because of this unloading action, the waggons must be uncoupled from the train. The waggons are held during the dumping procedure either hydraulically or by using a mechanical system with automatic locking facility. With lower capacities tippler charging is made by locomotives, whereas for higher capacities side arm chargers are used. The special hauling facilities developed by ThyssenKrupp Fördertechnik are much more suitable than locomotives for the exact and quick positioning of waggons, as well as for random cars. These devices are equipped with a lateral pivoting arm that engages with the waggon coupling. | ||
| Truck Tippler | ||
| Truck tipplers are used for unloading bulk materials from road trucks with stationary super-structures. The platforms are lifted with the help of hydraulic cylinders. During the tipping procedure the trucks are held either at the wheels or at the truck chassis. The procurement and continuous maintenance required by more mechanically complex self-discharging trucks results in higher costs. It may therefore be more economical to arrange tipping platforms at the unloading stations and using trucks with fixed load bodies. | ||
| Rotary Waggon Tippler | ||
| Rotary waggon tipplers unload the waggons turning through either 180° or 360°. Vertically and horizontally arranged hydraulically actuated waggon holding devices secure the waggons during the dumping procedure. These hydraulic holding devices make it possible to handle waggons of various sizes and are equipped with on automatic pressure-relief facility for waggon spring reassertion. If the waggons are equipped with rotary couplings, they are tipped in the train unit. In that case 40 unloading cycles and more per hour can be achieved with the rotary dumper. When the waggons which must to be unloaded are not equipped with rotary couplings, they need to be dumped individually, i.e. prior to running into the tippler they must be uncoupled from the train. ThyssenKrupp Fördertechnik have developed a special patented indexer with electrically regulated, shock free positioning of the waggon which allows individual waggons to be moved into the dumper. For advancing a train which may consist of 100 waggons of 120 t each the side-arm chargers can be used achieving tractive forces of up to a 1000 kN. | ||
