3 0 Vehicle characteristics The VEL400 track car is a two-axled vehicle designed for the servicing and maintenance of the overhead contact line (also known as catenary). It is fitted with a work platform (currently tower), a crane for lifting loads, a platform for carrying various items and tools, and a soundproofed cabin able of carrying a team of six people. As options, it can carry a pantograph and other equipment to measure catenary parameters and a cage for two operators (attachable to the crane). It is driven by a 6-cylinder diesel engine and has a maximum horsepower of 450 C.V. This power is transmitted to the axles by means of an electronically controlled hydrostatic transmission. The vehicle is fitted with all of the equipment required to circulate on railtrack, such as dead man s handle equipment (security device), and UIC-approved traction and buffer gear elements. Moreover, it is fitted with an electro-pneumatic brake system with compact brake blocks and shoes in accordance with UIC standards. The VEL400 has two speed ranges: Km/h and 0-5 Km/h. There is a control at the tower that allows circulation at 5 Km/h, as well as the proper movements of the platform. Besides, the crane has a remote control for itself. In case of an emergency, both crane and tower movements can be done with a manual hydraulic pump. All vehicle operations are controlled by means of a PLC, and a touch screen displays all the information concerning the track car. The VEL400 has power and pneumatic plugs to connect tools during work. VEL400 description leaflet Page 3 / 16

5 1 Cabin In this section, some photographs and drawings of each one of the track car s cabin components are shown: 1.1 Control desk It includes all the engine, brake, lighting and auxiliary controls, as well as the engine and vehicle information touch screen. A general view of the control desk can be seen on this page. VEL400 description leaflet Page 5 / 16

6 1.2 Side view of the control desk DEAD MAN S HANDLE JUNCTION BOX REMOTE CONTROL BATTERY CHARGER VEL400 description leaflet Page 6 / 16

7 1.3 Cabin view The cabin is able to carry up to 7 people, including the driver. The seats and cabin layout should be decided upon customer s likes. Inside, you can find also the auxiliary equipment, such as the heating devices, the cabinets and the fire extinguishers. 1.4 Remote control Located at the tower, the vehicle has a control that governs the tower hydraulic movements, the vehicle movement to a maximum speed of 5 km/h (accelerator and brake), and the horn. Besides, the crane has also a remote control, please see picture below: VEL400 description leaflet Page 7 / 16

8 2 Performance. The 336 kw (457 HP) diesel engine provides enough power to the hydraulic transmission to accomplish the daily tasks. The engine has a displacement of 11.1 litres and a maximum torque of 2080 N*m. As it was said, the VEL400 track car has two speed ranges, Km/h and 5 Km/h. The following are the average performances: top speed on a level track with no loads: 100 Km/h, on a 2% sloped track with no loads: 80 Km/h, on a 1.25% sloped track with no loads: 90 Km/h, on a level track and towing 150 T: 70 Km/h. Please see next chart, where high resistance forces and low friction coefficient have been considered, in order to get realistic results: 2% gradient resistance (no towing) Tractive effort Level track resistance (towing 150 T) Maximum adherence 1.25% gradient resistance (no towing) Force (N) Speed (Km/h) The diesel engine comes with silencer (catalytic filter as an option), so working on difficult places like tunnels can be achieved. The hydraulic transmission allows an easy driving, because all acceleration manoeuvres can be done with one lever on the control desk. It can pull another vehicle or can be towed, we can see its UIC equipment for those purposes on the next shot: VEL400 description leaflet Page 8 / 16

9 The brake system is also UIC standard, and its manufacturer is a reputed UICapproved maker. The system includes service, direct, parking and emergency braking, and then the sanding and horn devices. The driver can control all features from the desk. On that picture, we can see also the coupling hoses for the braking system. VEL400 description leaflet Page 9 / 16

10 3 Wheelset and suspension. There are two driving axles, powered by hydraulic motors of regarded maker. On this shot we can also see the suspension system: VEL400 description leaflet Page 10 / 16

11 4 Lighting While working by night, it is mandatory a good equipment to work efficiently. The VEL400 track car carries a complete range of 24 v and 220 v lights to do the task. Besides, with the help of a 15 KVA generating set, tools can be plugged for working. If preferred, work lamps can be installed instead of fluorescent ones, so lighting will be decided upon customer s likes. VEL400 description leaflet Page 11 / 16

12 5 The crane The crane plays an essential role on the VEL400 track car. It is located at the rear bottom of the vehicle, and it is folded in a way that provides good visibility to the driver. The crane can be manipulated by remote control or by levers. This is a picture of the crane and its jacks: The crane is incorporated with OLP system for overloading protection and stability assurance during turning. VEL400 description leaflet Page 12 / 16

13 6 The tower It allows to work at the catenary area. The tower has two movements: vertical and horizontal. It has folding handrails, 230 V electrical and pneumatic plugs for tools. There are also two steel rollers to allow the contact line a better positioning. Here we can see the tower from above: The floor dimensions are 2.4*2.9 m. The tower height from its floor to the rail is 3.5 m (folded) and 5.5 m (completely unfolded). The maximum lateral reach from the track center line is ± 2.9 m (horizontal movement). 6.1 Tower controls The work tower can be handled either from the local control or from the crane s hydraulic distributor. Please, keep in mind that the local control located on the tower should always be used, therefore the levers on the crane distributor are for emergency purposes only. The cylinders that move up/down the platform have security valves to prevent an unwanted comedown. Besides, the hydraulic motor that allows the horizontal movement has a negative brake, as a blocking device. In case of a general failure of the hydraulic system, there is a manual pump for keeping both the crane and the tower to their folded position. VEL400 description leaflet Page 13 / 16

14 7 Options 7.1 Catenary height measurement and viewing monitor. The catenary measurement consists of a pantograph, a device for knowing the height of the contact line, a display to show it, and a CCTV camera to see the horizontal alignement. There is a monitor inside the cabin (facing the driver) that enables both the catenary distribution and the two front-ends to be viewed. The latter is used to watch areas near the buffers, to enhance security during work. Moreover, the pantograph controls are to be found under the monitor, as well as its height record. And here we can see the cabin roof, where the measuring pantograph and other auxiliary devices are located: VEL400 description leaflet Page 14 / 16

15 7.2 Work cage Instead of the cargo hook a work cage can be coupled to the crane. It is made in polyester and it can carry two people and a tool box (maximum 220 Kg). 7.3 Diesel engine catalyst The diesel engine can include a catalytic filter to reduce emissions and therefore, protect environment and workers during tasks at tunnels, for example. 7.4 Remote control A remote control can be included with the vehicle. The operator would be able to control both the crane and the tower with only one device. VEL400 description leaflet Page 15 / 16

16 7.5 Air conditioning device The air conditioning device allows cool temperature in the cabin during hot days, therefore bringing some comfort during transport. It is located on the cabin roof, and controls are accessible from inside. The device can handle 3.5 KW of cooling power. VEL400 description leaflet Page 16 / 16
