KONAR Lift-gate systems

KONAR is the only manufacturer in Poland producing lift-gate systems designed for loading mini-mulda containers. Commonly known as “bramowiec,” these devices are available in two models: BK25S with a lifting capacity of up to 2,500 kg and BK35S with a lifting capacity of up to 3,800 kg.

These lift-gates are mainly mounted on light commercial vehicles ranging from 3,500 kg to 7,500 kg GVW. Due to their compact size, they are ideal for municipal and construction companies, allowing easy maneuvering in urban areas, especially in residential neighborhoods. The small vehicle GVW also helps minimize damage to city infrastructure during tight loading operations.

KONAR BK25S Lift-Gate

The KONAR BK25S, installed on a Mitsubishi Canter, is a classic example of a “bramowiec.” Its compact design makes it particularly suitable for municipal services and construction companies operating in urban environments.

Our KONAR dump trucks, available with single-, double-, or triple-side tipping, are mounted on two- and three-axle chassis and are widely used in transport, construction, municipal, and agricultural sectors.

Key Features of KONAR Dump Trucks:

• Robust construction using high-strength steel for superior durability (HARDOX, STRENX)

• Choice of steel or aluminum side panels

• Steel components and side panels are shot-blasted, galvanized, and multi-layer painted

• Side panels open on top or bottom hinges, with hydraulic tailgates allowing 180° rotation

• Hydraulic components from reputable manufacturers such as HYDROCAR and Binotto, ensuring easy access to spare parts

• Custom designs tailored to client needs and the capabilities of the supplied chassis

• All projects designed using modern 2D and 3D CAD systems

Since its inception, box bodies have been one of KONAR’s flagship products. With over 30 years of experience, a creative and modern design office, and an individual approach to each client, our bodies have gained recognition across Poland and abroad, including Scandinavia and Western Europe.
