VEHICLES OF HEAVY SHUNTING SERVICE

 

CME3M HEAVY SHUNTING SERVICE LOCO

The diesel- electric locomotive type 1520 Co´Co´66A ZV is 6 axle locomotive with electric (alternating- direct) power transmission, with weight of 120 000 kg. This locomotive is result of complex reconstruction of the original series CME3. Original parts bogies and main frame was reconstructed because of new aggregates positioning, the cabin is constructed as completely new unit. The locomotive is designed for heavy shunting service and freight transport with gauge of 1520 mm. The maximum speed is 90 km/h-1 , the locomotive is designed according to GOST 15150 (B1), the temperature range for locomotive´s aggregates is -40°C to +45°C.

The driving engine consists of Caterpillar 3508B SCAC (1000 kW) connected with traction synchronous alternator GS523-KUCHL2 (830 kVA) and synchronous alternator of subnets GS1101-UCHL2. Drive unit is used to retain the locomotive at full power with all equipment needed.

The cabin is resiliently placed on silentblocks, closer to rear part of locomotive. The interior equipment consists of two adjustable seats, adjustable footstools, security front heated windshield with washers and blinds, ceiling fans, side double glazed windows with openable part, radio station, fridge, cooking table and lockers.

Modular design of loco allows repairs by individual units and provides easy access to equipment installed in and significantly reduces the complexity of all types and forms of maintenance and repairs. Locomotive cabin provides better view, it is equipped with better ergonomics and it also disposes with high level of automation.

High reliability, simplicity and efficiency of control system allow significantly (more than 20%) reduction of operating costs. Increased reliability of the system reduces the cost of maintenance and repair in more than 50%.

DIESELELECTRIC LOCOMOTIVE 773

The dieselelectric locomotive 774 was created as the result of the complex reconstruction of the original series of 770 (T 669). The reconstruction resulted in increase of the installed power, operating and maintenance savings are supposed to be achieved, as well as improved the ecological parameters and operating life of the locomotive. The locomotive is designed for heavy shunting and freight transport on national, regional lines as well as sidings in Central European climatic conditions up to the altitude of 1000 m above the sea level, at temperature range from – 30°C to + 40°C and maximum relative air humidity of 90% at the temperature of 20°C. From the original locomotive the main frame was taken over, on which the necessary adjustments were made for the fitting of new aggregates, bonnets and cabin. There was a reconstruction on the travel to embed the frame on rubber – metallic blocks. There are two diagonally situated control panels in the cabin equipped with controllers of movement and electrodynamic braking. The cabin is fitted with two overhead ventilators above the operator’s position and with a „tropiko“ double roof in order to improve conditions in the summer months. There are two sprung seats that are adjustable alongside and vertically. The floor covering is made of antiskid treatment.  Front windows are equipped with adjustable sun protection blinds. The top of the panel and bonnet roofs was treated by anti-reflex dim surface. The locomotive has two original triple-axle chassis. Each axle is a driving one and is driven by TE 006 traction engines. The driving engine aggregate consists of CATERPILLAR 3512B SCAC combustion engine connected with SIEMENS DRASOV traction synchronous alternator. The engine cooling system is of liquid type with closed circuit and bypass. The auxiliary drives are driven by three-phase asynchronous engines from the auxiliary network 3x400 V with variable frequency through frequency changers.

The dieselelectric 756 was created as the result of the complex reconstruction of the original series of 753 (T 478.3) by mounting Caterpillar 3512B SCAC combustion engine with maximum output set to 1 455 kW, as a replacement of the original combustion engine K12V 230DR, as well as by mounting of an electrodynamic brake with maximum output of 1 710 kW. The reconstruction should result in significant operating and maintenance savings, as well as improved ecological parameters and the operating life of the locomotive. The locomotive is designed for semi-heavy and heavy track service on national, regional lines and sidings with gauge of 1435 mm, in Central European climatic conditions up to the altitude of 1000 m above the sea level, at temperature range from – 30°C to + 40°C and maximum relative air humidity of 90% at the temperature of 20°C. The maximum speed of the locomotive is 100 km/h. Travel, case, cabins and the min frame were preserved from the original locomotive and necessary adjustments were carried out in connection with the operation and mounting of the new aggregates. There was a reconstruction on the travel to embed the frame on rubber – metallic blocks. In each cabin, there is a control panel on the right side with controllers of movement and electrodynamic braking. The cabin is fitted with two overhead ventilators above the operator’s position in order to improve conditions in the summer months by air-conditioning. There are two sprung seats that are adjustable alongside and vertically in the cabin. The floor covering is made of antiskid treatment.  Front windows are equipped with adjustable sun protection blinds. The top of the panel and bonnet roofs was treated by anti-reflex dim surface. The locomotive has two original double-axle chassis. The locomotive has two original double-axle chassis. Each axle is a driving one and is driven by TE 005E traction engines. The driving engine aggregate consists of CATERPILLAR 3512B SCAC combustion engine connected with SIEMENS DRÁSOV traction synchronous alternator. The engine cooling system is of liquid-type with closed circuit and bypass. The auxiliary drives of the locomotive are driven hydraulically resp. by direct-current electromotors.
