Carriage with trailer carriage and transport bar
Carriage System for construction sites
Set up and function
The carriage with trailer carriage and transport bars is mainly used in gravitational operation in the construction industry for lifting, transporting, lowering and moving of long and heavy parts such as e.g. pressure pipes and gas pipelines, or also for transporting concrete and gravel. The transport bars also prevents the load twisting and twisting of the mainline cable is also not possible even if the lowered load is left hanging for some time. The retracted load is locked in both the carriage and in the trailer carriage, so that the load is doubly protected against falling during the run. The trailer carriages are used with our standard HY-4 and HY-7 carriages for maximum load capacities of 5 t for the HY-4 and 10 t for the HY-7. The carriages are also controlled using our radio-telephones. The system with carriages, trailer carriages and transport bars is recognised as being very reliable and the costs for service and maintenance compared to motor-driven skyline crane are very low. The transport bar is available in two different lengths, 2.5 m and 3.5 m.
Advantages
- The trailer carriage is directly controlled from the carriage
- Increased safety through 2-fold hoisting when raising and lowering
- Increased safety during the run though locked load on the carriage and trailer carriage when the hook is completely retracted
- Higher load capacities – 5 tonnes for the trailer carriage with transport bar
- Long and heavy loads can be transported, lifted and lowered horizontally
- The lowering height is not limited by a hoist-drum in the carriage. (Depends on the mainline on the pulling winch)

HY-4 Mainline Clamp with Transport bar
The HY-4 carriage with transport bars can also be used with a mainline clamp. The mainline clamp in the pendulum allowed repeated movements for loads lowered at any height. It is operated with the portable radio equipment and can be used with trailer carriages with transport bars. The especially large mainline clamps in the load pendulum reduce wear on the mainline cable, which is also locked in the load pendulum when the load is completely retracted.

FSI control sytem
Wyssen’s own developed FSI control system is installed in the HY-4 and HY-7 carriages.
Advantages
- operable with radio
- Conventional timer switch possible (without radio signal)
- automatically switches off when not in use
- Erroneous clamping after passing a support is prevented
- clamping with a radio signal during the journey via set speed no longer possible
- Automatic emergency stop if the programmed speed limit is exceeded
- All parameters can be individually adjusted (speed, clamping and delay times)
- depending on the mode set, it is also possible to start/stop the diesel engine or rewind the haul-back cable
- protected against clamping if the battery is discharged
- Battery status display
- Resistant against moisture, vibration and impact due to completely enclosed electronics
- Software updates with improvements and upgrading are possible at any time, latest micro-computer control system
