Overview
Solutions ready for installation to meet individual requirements
Our crane end carriages, which we have developed in various designs, offer flexibility and high operating reliability. These compact, modular rail-mounted travel units can be connected direct to crane girders and load-bearing structures. Our end carriages consist of a torsionally rigid box section and complete travel units with geared motors and wheels from the Demag modular system, which can be configured for all load capacity ranges. These combinations result in solutions to meet specific application requirements for safe crane and machinery travel motions that are kind to the rails.

KTL corner-bearing end carriages
Convenient long and cross-travel motions
Our corner-bearing end carriages are versatile, modular rail-mounted travel units of torsionally rigid box-section design. They can be connected direct to load-bearing superstructures – for cranes or crabs. Further benefits:
- precise single or double-girder design with up to four travel wheels
- can be configured for all load capacity ranges
- optimised design of the entire crane system
- convenient adjustment and maintenance
- save time for handling during assembly.
Compact, robust, high performance
Outstanding performance
- Travel wheels made of high-quality spheroidal-graphite cast iron for low operating noise
- High resistance to wear
- Design to DIN 5018 (H2B3 – H4B6)
- Buffer options (hydraulic buffers, cellular plastic buffers)
- Tandem end carriages with connecting elements
Individual solutions
- Drive option with one, two or four driven travel wheels
- Corner-bearing wheel sets with diameters from 250 to 630 mm
Convenient assembly
- Direct connection to the crane girder – with one or two machined connection surfaces depending on the design
- Simple, time-saving handling
- Simple maintenance and adjustment thanks to corner-bearing wheel sets that can be rolled out of the girder
- No additional components need to be removed
Low-maintenance drives
- No special tools required
- Compact, matching ZBA motors and AU gearboxes
- Direct splined-profile connection to the travel wheel shaft (easy to remove)
- Flexible torque-load connection to the end carriage thanks to elastic torque arm
- Low-noise operation thanks to ground helical gear wheels running in an oil bath
