Description
For all repair and assembly jobs.
According to European standards, all Yale workshop presses can be used without any additional protection devices as the piston speed is below 10 mm/s.
For special applications additional safety equipment (e.g. protection grid or two-hand-safety-control) can be offered on request.
Applications
• Pressing and removing of bolts, shafts, bearings.
• Straightening of beams, profiles, axles, shafts.
• Forming, bending, crimping.
• General load tests and tests of weld specimens.
• Stamping, cutting, punching.
• Pre-adjustment of tools.
Equipment of all presses
Features
• All workshop presses are ready to use, including hydraulic oil, oil level gauge.
• High pressure-hydraulic hoses.
• Glycerine-damped pressure gauges.
• Fixing holes in base profiles, adjusting device for press table and head, swivelling pump console, conversion chart: Pressure-force etc.
Description of the hydraulic cylinders
Features
• Cylinders made from chromium-molybdenum steel, heat-treated and with metric mounting threads in the piston.
• Double bronze bearing of the hard chromium-plated piston.
• Piston return through spring or hydraulically.
• Mounting thread in the piston.
• Available piston strokes from 150 up to 500 mm.
Description of the press-frame
Features
• Robust, torsion-resistant construction.
