HY-4 and HY-7 Carriages The ideal unit for long-distance cableways. The HY-4 and HY-7 carriages are characterised by 4 guide pulleys and a pendulum to support the load hook and to relieve the mainline cable while travelling. As a result, the mainline cable will not be damaged, even by the heaviest impacts due to long timber loads. Various options are possible: - Remote radio control of the clamping to the skyline cable - Mainline cable clamp in the pendulum - 3-cable drum slack-pulling device - Motorised slack-pulling device with the power unit as trailer For the transportation of long and heavy goods, a trailer with a transport bar is installed. The carriages are all equipped with a mainline cable breakage safety device. 12 Technical Data HY-4 HY-7 Length 1,270 mm 1,560 mm Width 280 mm 390 mm Height 900 mm 1,116 mm Hydraulics 100 bar 100 bar <strong>Skyline</strong> cable 14 - 36 mm up to max. 45 mm Mainline cable 9 - 16 mm up to max. 20 mm Carriage weight up to max. 320 kg approx. 630 kg Load capacity 4,000 kg 7,000 kg Time switch with clamping and delay time Advantages of the HY-4 and the HY-7 . Novel conception with very few moving parts . Self-contained compact construction with moving parts on the inside . Easy to service despite the compact construction . Minimum wear to skyline cable due to 4 large glide pulleys . Minimum wear to mainline cable through the increased size of the lifting pulley . Plenty of room for the simplified pull-in of the mainline cable . Smooth passage over the supports thanks to the 4 guide pulleys . Passes over large and small WYSSEN support saddles . Complete construction made from high-grade steel . Safety guards to prevent derailment from the skyline cable, allowing fast travelling across saddles . Large swinging angle of pendulum . Very careful handling of the skyline cable thanks to the special clamping grove . Screwed construction, allowing the chassis to be dismantled into small replaceable parts . Standard cable breakage safety device
Options In addition to the standard models, the HY-4 and HY-7 carriages can also be fitted with the following options (can also be retro-fitted): HY-4F radio switching For moving over short distances with the load docked Advantage . Precise clamping and release at the touch of a button . Hooks swings out for clamping during slow descent Clamp Speak Open . Does not have to be raised when clamping during slow descent, even with load . Remote control integrated into hand held radio . Electronic time release remains active if the wireless communication is interrupted . Protected against clamping when travelling too fast • Protected against clamping when the battery is low 1 2 3 4 Traction cable clamp HY-4Z For travelling with lowered load Advantages . Clamp integrated into the load pendulum • With the hook fully withdrawn, the load is docked in the pincers • Can be retrofitted to any HY-4 Trailer Carriage For the hoisting, transportation, lowering and laying of long and heavy parts, such as pressure pipes and gas pipelines Advantages . The trailer is directly controlled from the carriage . More safety and load capacity Load hooks for the HY-4 HY-4M motorised slack-pulling device HY-4MF, HY-4MZ Advantages . The hook rarely jumps out, even in horizontal runs . On request, the slack pulling procedure can start automatically . Traction adjustable from 50 - 400 kg . The mainline cable always remains pre-tensioned up to the winch . Das Zugseil bleibt immer vorgespannt bis zur Winde The HY-4M is also available with radio switching or mainline cable clamp.
