Typ PUDZ III – Heavy Duty Shock Absorbers

Application areas:

• Crane systems
• Offshore / Ship
• Steel industry
• Mining / Material handling
• Railway technology
• Railbound hall roofs / gates
• Mechanical / Plant engineering

Product type:

• Buffer / Damper

Product description

Particularly suitable for crane systems, heavy machinery and handling equipment of all kinds.
MADE IN GERMANY.

• Own production in Germany
• Buckling loads, especially for long strokes will be includes into the buffer calculation / Highest safety!
• Integrated piston accumulator with nitrogen filling
• Progressively rising restoring force (buffer force) at the end of stroke
• Suitable down to -50°C – with special heating pad!
• Piston rod double chromed – Marine protected (standard)

PUDZ III is an optimization of the known PUDZ II and corresponds to its technical performance data.

Functional principle

• Piston size ø 63 mm – ø 160 mm
• Stroke lengths 50 mm to 1600 mm
• Energy absorption up to 582 kJ/stroke
• Buffer force up to 1000 kN
• Flange mounting:
  – Front flange “EF”
  – Bottom flange “FF”
  – Pedestal flange “SF”

With Pressure-Closing-Valve: Allows pushing the hydraulic buffer at creep mode (10% of the nominal speed) WITHOUT getting a real buffer impact at the end of the stroke!

Technical benefits

• Self-contained system, suitable for any mounting positions
• Buckling loads, especially for long strokes will be includes into the buffer calculation / Highest safety!
• Integrated piston accumulator with nitrogen filling
• Progressively rising restoring force at the end of stroke
• Short delivery times

Options

• Bellows for dust protection
• Pressure-Closing-Valve (Buffer stroke can be used in normal operation without getting a buffer impact)
• Special flange mounting
• Low temperature (-50°C)
• High temperatur
• Piston rod monitoring system
• Piston rod protection (Suitable for outside)
• Buffer head catching system (buffer against buffer)
• Buffer head catching ring (position stabilization)
• Special painting (Please specify RAL color)
