Signal lamps

Our product range includes type SSV 136 main signal lamps (136 mm diameter), type SSV 70 shunt signal lamps (70 mm diameter) and type SSV 210 or 300 level crossing road signal lamps (210 or 300 mm diameter), based either on the existing or on new technology (bulb filament / LED) and including the appropriate modifications for the signalling system of the Slovenian Railways.

As a manufacturer of signal lamps, we are committed to the ongoing development of new technologies in this field and supplying spare parts for maintenance and repair. As part of our service commitment we also specialise in the refurbishment of signal lamps.

 

Refurbishment of signal lamps

First we disassemble the signal lamp and then clean and repaint it with the standard SSV colour. We replace the most important parts of the lamp, such as the lamp socket, the seals and the fasteners. Other parts, such as the condenser, the colour filters, the diffusing glass and housing parts are usually only cleaned. If they are no longer usable, we replace them with new original parts from our own production. We only use certified genuine spare parts for refurbished signal lamps. After re-assembly, the lamp is calibrated and aligned in accordance with the relevant regulations and standards.

In most cases, the refurbishment process costs less than half that of a replacement.

All new type SSV 136 signal lamps are designed for speeds of up to 160 km/h. Based on the necessary certificates and original technical documentation, HESER has the exclusive right to manufacture and service type SSV signal lamps in their field of application. 

 

Main signals

With HESER, our customers can order complete signals, including a hot-dip galvanized signal head with a silumin cable terminator, a hot-dip galvanized signal post, a silumin signal cabinet equipped with rubber vibration dampers, stainless steel fasteners and a precast concrete foundation.

Signal gantries with one or more signal heads can be supplied by special order. Each signal gantry is unique and requires a static analysis of the foundation and the complete gantry structure. We also supply the required technical and other documents. The steel gantry structure is protected against corrosion by hot-dip galvanizing. All fasteners are made from stainless steel.

We also carry out restoration works on main signal and gantry foundations. Replacement signals are installed after completing a static analysis and obtaining the appropriate permits.

 

 

 

 

 

 

Foundations

In addition to main signal foundations we also supply concrete foundations for shunt signals, road traffic lights, telephone boxes and barrier drives. Individual foundation elements (cubes) are interconnected with studs protected with plastic caps. We have developed our own models for the foundations; these are based on a static analysis and the appropriate permits/certificates. 

 

Signal boards

We manufacture 1 and 2 aspect signal boards with a reflective surface. The mounting brackets are made of stainless steel and are designed for easy installation. The signal board mounting rack is suitable for all different signal post types. Our durable and maintenance free signal boards are equipped with a high quality reflective surface that is highly visible under any light condition (day or night).

 

Indicators

Our indicators consist of a stainless steel housing and feature an extremely light construction, a black paint coating and fibre optic technology, offering numerous advantages:

• extremely good visibility at all distances,
• easy installation and low-cost maintenance,
• only two long life halogen lamps (main and standby) required,
• low power consumption,
• automatic switchover from main to standby lamp,
• The light bulb can be installed up to 18 meters from the indicator housing (on bridges, in tunnels, on signal posts, gantries and in other hard to reach places). Another advantage of this solution is the easier and less dangerous light bulb change.
• after a minor modification of the electromagnetic relay system, the indicator is also compatible with the older indicator type,
• support for all types of indicators used by the railway due to fibre optic technology,
• universal mounting solution for easy installation on any base, 
• indicators with LED technology are currently in the development phase.

  

 

Shunt signals

The cast stainless silumin alloy housing is equipped with type SSV 70 signal lamps. The black painted housing is waterproof and is attached to a hinged base for easier alignment of the signal. The base is mounted on a standard precast concrete foundation and is fastened with foundation bolts. The bolts are protected against corrosion and the top nuts are fitted with plastic caps. The signal door is equipped with a latch and a standard lock.

  

 

Limit track signals

The signal housing is made from a hot galvanized metal structure, which prevents rust and corrosion and requires very little maintenance. The signal can be installed on all standard signal posts. The signal is equipped with type SSV 70 lamps (diameter 70 mm) installed in the closed cabinet. It features superior visibility, easy maintenance and a long life cycle. The signal housing is waterproof and has anti-fog ventilation. The front panel of the signal head is painted black and meets the requirements of the railway signalling regulations.

 

Signal cabinet with vibration dampers, the cable distribution box and signal head cable terminals

All three products are made from silumin and are waterproof. The mounting structure of the signal cabinet prevents the transmission of vibrations from the line to the electronics in the cabinet, which reduces the impact of vibration on the signal (signals reverting to stop).

The lower part of the signal cabinet provides space for a standard connection strip or an appropriate connector version for connecting the cable to the electronics.

The distribution box is equipped with a certified 10 pole connection strip which can be used for connecting the trackside equipment (point machines, switch-on sensors for level crossings, electric points heating, etc.). The signal head cable terminator is equipped with a built-in 21 pole connection strip.

 

Level crossing signals

The version with the 136 mm signal lamps and the 60 L or D diffuser glass is still available. Nowadays, we supply lamps from the traffic light program with a diameter of 210 mm or 300 mm in incandescent or LED technology. We deliver either individual lamps, complete signal heads including a high-quality bell or complete signals with a hot-dip galvanized post and a precast concrete foundation. We also offer precast concrete foundations for barrier drives of different manufacturers, including the appropriate certificate and static analysis.

 

 

 

 

Level crossings barrier arms

We manufacture standard as well as non-standard length barrier arms. Our level crossing barriers are light, made of aluminium and feature a special extruded square profile. Barrier arms are finished in standard red and white signal colours and are equipped with a breakaway insert, reflectors and LED lights.

 

   

 

Barrier arm breakaway inserts

We produce metal (silumin) breakaway inserts for all barrier arm lengths, both in square as well as in hexagonal design.

 

 

  

Point indicators

The point indicator is made of an extremely light yet very strong aluminium casing. Our product range includes three different indicator versions: indicators with electric lighting, indicators with oil lighting and indicators with a reflective surface (highly visible even at night – the most commonly used version nowadays). The indicator is designed and constructed for easy use and maintenance.

To provide high quality at a low cost and ensure a long life cycle, the electric version is equipped with a built-in lamp socket, which enables the use of the standby filament of disused 30V-15/15W signal bulbs.

Impedance & glued joint meter – ZM8

The meter is intended to measure the impedance of railway tracks (bed impedance) and determines the ability of the track bed to ensure the proper functioning of audio frequency track circuits, thus enabling the optimum adjustment and control of track circuits. Impedance measurements are made at 8 kHz. To ensure the minimum influence of external voltages on the measurement accuracy, measurements are frequency-selective. The meter is equipped with a potentiometer and a measurement function selector switch, enabling users to adjust all settings and perform all tests of the circuit in accordance with the appropriate calibration manual for audio frequency track circuits. The additional ZM-8S probe enables the measurement of glued joints and the troubleshooting of normal track circuits. Using the ZM-8S probe, users can selectively measure and track the 8 kHz currents through the rails in order to detect possible leaks. The meter is certified and has its own battery power source and battery charger.
