Product Overview

Struggling with mixed cargo contracts?

Stop buying multiple specialized trailers. From concentrated 80-ton mining excavators to oversized wind turbine blades, solve all your transport challenges with one versatile solution designed for rugged terrains.

Why Choose Kales Telescopic RGN?

In the heavy transport industry, versatility is profit. We engineered this trailer to solve three major problems:

1. One Trailer, Two Missions

Closed Mode (80T): For concentrated heavy loads like crushers.
Extended Mode (+4.5m): For long cargo like wind towers and pipes.

2. Safer Front Loading

Drive equipment directly onto the deck from the front. Eliminates dangerous rear ramp climbing angles for top-heavy machinery.

3. Low Ground Pressure

2-Line 4-Axle (16 tires) design doubles tire contact area. Ideal for preventing sinking in soft soil or muddy mining sites.
