Catenary Masts for tram and trolleybus lines
We design and manufacture steel load-bearing structures for electric transport catenary systems based on bent multi-sided shafts. The masts carry the tram and trolleybus overhead line and can also carry insulated cable and lighting. Multi-sided poles start from UAH 35,000 each including VAT.
Types of masts
The masts are designed to the standards in force in Ukraine. The range for ground installation is 7.3 to 9 m high.
Multi-sided catenary masts
For suspension of the overhead line of urban transport: tram, trolleybus, metro.
Heavy-duty multi-sided masts
Load-bearing masts for higher loads, including those with additional equipment.
Combined masts
Overhead line, insulated cable and functional lighting of squares, road interchanges, roads, embankments, alleys and boulevards.
Masts for ground installation
The BKMG and BKM series, 7.3 and 9 m high, with design loads from 800 to 2500 kg.
Advantages of steel masts
Lighter than concrete
Smaller size and weight: cheaper transport and installation, less load on the foundation.
Strength and durability
High tensile and bending strength, longer service life and lower risk of accidents.
Flexible design
The design can be adapted to the specifics of the road and transport infrastructure.
Neat appearance
The masts fit the architecture of the city. Protection: hot-dip galvanising to DSTU EN ISO 1461:2024, optionally painting.

Catenary masts: technical specifications
Catenary pole prices
Indicative prices from the price list (September 2026, including VAT, excluding delivery and installation): multi-sided tram and trolleybus catenary poles from UAH 35,000 each; multi-sided power poles 7–12 m from UAH 25,000; combined poles 7–12 m (catenary and lighting) from UAH 28,000. Poles for installation in the ground (BKMG / BKM foundations) are priced on request.
What we take into account in the calculation
- mechanical loads: wind, snow, self-weight, load from the contact wires
- soil type at the installation site
- geometry of the mast: height, tube diameter
- mast material
- distance between masts
- load from the contact wires depending on the type of electric transport
BKMG and BKM series (catalogue)
Catenary masts for ground installation 7.3 to 9 m high, made to TU U 25.1-39573934-001:2016. The sizes differ by standard load P (800, 1200, 1500, 2000, 2500 kg) and shaft dimensions.
Marking example: BKMG-9-15 is a catenary mast 9 m high with a standard load of 1500 kg.
Manufacturing
Multi-sided masts are made on a production line: cutting of trapezoidal blanks, automatic plasma cutting, a hydraulic sheet bending press with automated blank feeding and automatic welding of longitudinal seams.

Catenary masts: frequently asked questions
What transport are the masts for?
For the catenary of trams, trolleybuses and metro. The masts can also carry insulated cable and luminaires to light squares, interchanges, roads, embankments, alleys and boulevards.
What heights are available?
In our catalogue the range for ground installation is 7.3 and 9 m. Other sizes are designed individually.
What do you need for the calculation?
The load from the contact wires, the wind and snow regions, the soil type, the mast height and the distance between masts. A technical specification form is available. Leave blank whatever you do not know and we will clarify.
What coating do the masts have?
Hot-dip galvanising to DSTU EN ISO 1461:2024, optionally with an extra paint coat.
Do you install the masts?
We design and manufacture the masts. Installation is carried out by a specialised organisation according to the work execution plan.
How much do catenary poles cost?
Multi-sided tram and trolleybus poles start from UAH 35,000 each, power poles 7–12 m from UAH 25,000, combined poles 7–12 m from UAH 28,000 (including VAT, excluding delivery and installation).
