Busbar systems are a modern and efficient way to supply power to moving equipment—cranes, hoists, trolleys, and other industrial mechanisms. They have long outperformed traditional solutions due to their reliability, convenience, and durability.
Among the different types of busbar systems, trolley and monorail (single-pole) systems hold a special place. At first glance, they perform the same task—but in reality, they differ in design, technical specifications, and most importantly, the conditions in which they are used. Let’s look at the key differences and which option may be right for you.
Trolley Busbars: A Classic for Stable Environments
A trolley busbar is a power supply system where copper conductors are housed within a shared protective casing (PVC or aluminum), and the current collector with copper-graphite brushes glides along these conductors.
This type of busbar is widely used indoors—in workshops, warehouses, and logistics zones. It’s well-suited for standard operating conditions without extreme temperature fluctuations or high moisture exposure.
Advantages:
-
Simple construction
-
Easy to install and maintain
-
Great for stable indoor environments
-
Cost-effective solution
However, for outdoor use or in challenging conditions (moisture, dust, snow), trolley busbars require more maintenance. Dirt can enter the casing, and in cold seasons, ice can form inside.
Monorail Busbars: Built for Harsh Environments
Monorail busbars are specifically designed for outdoor and aggressive environments. In this system, each copper conductor is insulated within its own channel, and contact with the current collector occurs through a narrow, protected slot. This design prevents the ingress of snow, dust, and moisture, significantly reducing the risk of malfunction.
Advantages:
-
Protection from ice and contamination
-
Reliable performance at temperatures down to –50°C
-
Suitable for outdoor installations and harsh indoor environments
-
Minimal maintenance required

What About Flexible Cable Systems?
Flexible cable systems are still used in some facilities, especially in older projects. However, they have several serious limitations when applied to systems with frequent or intensive movement:
-
Limited lifespan: cables wear out due to constant bending and friction
-
Higher risk of mechanical damage, especially with unstable suspension systems
-
Difficult maintenance and replacement, particularly in busy production areas
-
Restricted mobility: cables require more space for movement
Unlike suspended cable systems, busbars are fixed, rigid solutions that ensure stable contact and predictable performance even under heavy loads. For equipment that moves along a defined track and requires uninterrupted power, a busbar system is a more reliable and long-lasting choice.
Which One to Choose: Trolley or Monorail?
Trolley busbars are ideal for:
-
Indoor environments with mild climate control
-
Relatively clean settings
-
Normal temperature ranges
Monorail busbars are the best choice for:
-
Outdoor installations
-
Dusty industrial facilities
-
Locations with high humidity and temperature fluctuations
