Cable transport carriage HY series

The HY-4 carriage is used principally as a long-distance cable crane in the forestry and construction industries. It has four distinguishing guide pulleys to conserve the skyline and for gentler transit over the supports. The load pendulum is available with or without a large-dimensioned mainline clamp. In both versions the load hook is incorporated into the pendulum and the mainline is relieved of the weight during the run, so that the mainline will not be damaged, even by the heaviest impacts of long timber loads during rapid descents. The suspended load is also protected against the cable twisting, so that damage to the steel wire cable is also prevented. Like the HY-2 type, the HY-4 carriage is also equipped with theWyssen FSI carriage control system. It is operated using specially programmed buttons on the radio, as are all of our carriages. It can, however, be switched over at any time to the conventional timer switch, so that the system can be operated without remote radio control. In addition to the standard version, the HY-4 carriage can be fitted with various options, such as a motorised slackpuller, a trailer carriage with bar or a mainline clamp. The HY-7 carriage is technically identical to the HY-4 carriage and is mostly used in the construction industry. The difference is that the HY-7 is significantly larger and stronger and is designed for load capacities of up to 7 tonnes.
