2500-10000 kN nominal pressing force accommodates large-diameter axle assemblies (up to 5000mm gear diameter). Single machine replaces 2-3 traditional presses. Designed for continuous heavy-duty industrial environments (metallurgical, mining, large motor manufacturing).
Horizontal architecture enables gravity-assisted axle loading via traveling crane (optional on larger models). Eliminates manual vertical lifting; reduces operator fatigue and injury risk. Improved workflow efficiency compared to vertical press designs.
C-frame structure composed of work table, support column, upper cross-beam connected via 5 tension rods. Heavy-duty rigid design without frame deformation. Four precision guide columns (chrome-plated after quench hardening) ensure straightness ±0.1mm.
0-4 mm/s pressing speed (0-2 mm/s on higher-capacity models) enables optimization per material properties and geometry. Slow speed for delicate assemblies; higher speed for standard applications. Maximizes throughput without compromising part integrity.
Pressure relay triggers automatic shutdown at system overpressure. Mechanical overload relief valve provides backup protection. Dual emergency stop buttons (fixed beam + control console). Oil temperature monitoring with automatic alert/shutdown at 60°C.
Air-cooled hydraulic system maintains optimal 45-55°C operating temperature. Prevents viscosity degradation during continuous heavy-load operation. Automatic alarm at 60°C threshold prevents thermal system damage.
Main cylinder: Single-acting piston cylinder mounted on upper cross-beam. Piston rod connects via flange to guide block assembly. Cylinder material: Premium forged steel ensures uniform material properties. Pressing force range 2500-10000 kN accommodates diverse industrial applications.
Premium structural steel, fully stress-relieved. Multi-pass welding per ISO 5817 inspection standards. Furnace annealing eliminates residual welding stress. Precision ground bearing surfaces.
Single-acting piston cylinder, bore 160-400mm, stroke 600-1200mm. Pressure range 180-280 bar adjustable. Premium forged steel cylinders with imported high-reliability seal materials.
Variable displacement swashplate pump 50-100 cc/rev. Pressure 0-280 bar adjustable relief. Proportional valve speed regulation 0-4 mm/s. Accumulator 20-30L surge tank with air-cooled radiator.
Industrial Siemens controller with button interface. Point-action manual jog + semi-automatic cycle control. Pressure relay automatic shutdown on overpressure. Dual emergency stops fixed + console.

Application: pressing large industrial bearings, gear wheels onto axle shafts. Typical load: 3150-6300 kN. Material: steel axles, cast iron gears. Key requirement: precise axial positioning, no part damage.
Application: assembly of large-diameter axles for bucket wheels, reclaimers. Typical load: 5000-8000 kN. Material: forged steel axles (large diameter). Key requirement: heavy-duty reliability, minimal maintenance.
Application: rotor shaft assembly, bearing hub pressing. Typical load: 2500-5000 kN. Material: steel shafts, aluminum hubs. Key requirement: precision alignment, no shaft deflection.

Positioning improved to ±0.2mm; bearing preload consistency ±0.5 kN maintained; production rate +25%; achieved ISO 9001 quality assurance.
Different capacity and speed trade-offs. 2500KN model: larger 700mm stroke, faster speed 0-4 mm/s. 3150KN Standard: smaller 600mm stroke, same speed. Choose based on application: larger diameter gears → larger stroke needed.
Mechanical pressure relief valve (primary) sets maximum system pressure. Pressure relay (secondary) provides electrical shutdown backup. Two independent emergency stops enable rapid machine halt from either control location. Oil temperature monitoring adds third layer of protection.
Depends on load, stroke, speed. Example (3150KN, 600mm stroke, 2 mm/s): Approach (fast) 2s + precise press (slow) 15s + return 3s = ~20 seconds total cycle. Operator manual point-action optional for non-repetitive work.
Yes. T-slot work table accommodates custom fixtures for complex parts. Guide block ensures vertical alignment regardless of part shape. Pressing force distributes uniformly if fixture properly designed.
500-hour intervals: hydraulic oil analysis, seal inspection, bearing lubrication check, guide column cleaning. Thermal monitoring: check cooler efficiency quarterly. Pressure valve calibration: annually. Typical maintenance window: 4-6 hours.
