Diesel Hydraulic Power Unit for Emergency Cable Car Drive - Grünberg

As part of the modernisation of the Grünberg cable car in Gmunden, a complete overhaul of the main and emergency drives was undertaken.

Project description:

• Two large cabins each with a capacity of 60+1 passengers
• Operating (incline) length: 2025.46 m
• Height differential: 550.89 m
• Diesel engine incl. frame with 129 kW drive power
• After starting, automatic ramp-up of the diesel engine from idle to full operating speed
• DANFOSS POWER SOLUTIONS closed circuit, high pressure variable displacement axial piston pump
  (controlled by a SIEMENS control unit in the driver's cab)
• Hydraulic joystick for emergency operation in the machine room
• Open brake circuit pump (as soon as the operating speed of the diesel engine increases due to a lack of
  braking power, the system is automatically and gently brought to a halt by hydraulic means using a proportional pressure limiting valve)
• REGGIANA RIDUTTORI planetary gearhead in cable car design and DANFOSS POWER SOLUTIONS axial piston fixed displacement motor (engaged in the cable car sprocket during emergency operation)
• The new Grünberg cable car entered public operation on 14/06/2014

Hybrid Valve Block for Harvester Traction Winch

This is a hybrid valve block specially developed for the forestry industry. It consists of a DANFOSS POWER SOLUTIONS PVG32 proportional valve, combined with a COMATROL-HIC block. The subsystem designed by HAINZL combines the main functionality of the proportional control system with the cost effective and space saving design of the cartridge block technique. In addition, the entire system comprises customised HAINZL mobile control which, according to expert opinion, has become one of the most efficient harvester traction winches on the market.

Control System for Forestry Cabin Cranes

HAINZL developed a standalone electro-hydraulic control system for forestry cranes. This system is used in forestry cabin cranes. The major benefit of the new steering system is the time saved during assembly, commissioning and service, due to the customer friendly Plug & Play principle. Settings can be entered via a display panel. To control the crane, there are two joysticks based on fieldbus communication. The valve control block specially developed for mobile use can be mounted on the outside of the vehicle adjacent to the proportional valve. All parameter signals - with ramps and limits - are transmitted to the crane's hydraulics. The control can be configured individually for different users.

Centralised Lubrication for 5-Axis CNC Machine

HAINZL equips machine tools from the world's market leaders in CNC machining with total loss lubrication systems for gears, guideways and spindle bearings. These are modular lubrication solutions designed specifically for each individual customer, and can thus be added easily to existing systems. The high quality and reliability gives our partners total confidence in our expertise.
