Product Overview
C-Frame Precision. Open-Throat Access. Maximum Flexibility.
The KAVDO Single Column Hydraulic Press (Y41 Series) features a monolithic C-frame cast/welded body with an open-throat design that allows workpieces to extend beyond the frame width. The single-column architecture provides unobstructed access from front, left and right — making it the most ergonomic and space-efficient hydraulic press for straightening, press-fitting, stamping, bending and light forming tasks.
With servo-hydraulic proportional control, the press delivers infinitely adjustable pressure and speed throughout the entire stroke — from gentle press-fit assembly to full-tonnage stamping — all programmable via PLC with touchscreen HMI for instant recipe recall and rapid changeover.
- C-frame open-throat design for oversized workpiece handling
- Three-sided unobstructed access for manual or robotic loading
- Proportional pressure & speed control throughout full stroke
- Built-in return cylinder for automatic ram retraction
- PLC + HMI with 100+ recipe storage for instant job changeover
Performance Highlights
Key Advantages
The KAVDO single column hydraulic press combines an open C-frame structure, servo-hydraulic precision and compact footprint — delivering unmatched accessibility and versatility for straightening, assembly, stamping and light forming operations.
Open-Throat C-Frame Design
The single column C-frame provides a deep open throat that allows workpieces to extend beyond the frame width on three sides. Long shafts, wide plates, pipe sections and irregularly shaped parts can be positioned freely without interference — eliminating the size restrictions inherent in four-column or H-frame designs.
Full-Stroke Tonnage Control
The hydraulic press delivers full rated tonnage at any point in the stroke — not just at bottom dead center like mechanical presses. Adjustable approach speed, pressing speed and return speed via proportional valves allow precise cycle optimization for every application, from slow press-fitting to rapid stamping.
Servo-Proportional Precision
Variable displacement piston pump with proportional pressure and flow valves provides stepless adjustment of tonnage (0–100%) and ram speed via PLC. Stored recipes enable instant recall of process parameters — ensuring repeatable quality on every cycle while reducing changeover time to under two minutes.
Compact Space-Saving Footprint
The single column design occupies up to 40% less floor space than equivalent four-column or H-frame presses. No foundation pit required for models up to 100 tons. The compact design fits easily into existing workshops, production cells and maintenance bays without facility modifications.
Built-In Safety Systems
Hydraulic overload protection prevents frame and die damage from unexpected resistance. Two-hand anti-tie-down controls, optional safety light curtains, adjustable stroke limits, pressure relief valves and emergency stop circuits ensure full operator protection in compliance with CE and ISO safety standards.
Low Investment & Operating Cost
Single column presses offer the lowest capital investment per ton of pressing force in the hydraulic press category. Simple hydraulic circuit design means fewer components, easier maintenance and lower spare parts inventory. Energy-on-demand servo pump cuts electricity costs by 30–50% compared to fixed-pump systems.

How It Works
4-Step Single Column Press Workflow
From recipe selection to finished part — every stage is precisely controlled with programmable tonnage, variable speed and automatic ram retraction for safe, consistent and efficient production.
1
Program & Setup
Select a stored recipe on the HMI touchscreen or create a new one — set tonnage, approach speed, pressing speed, stroke depth, dwell time and return speed. Install die or fixture and verify safety interlocks. Changeover takes minutes.
2
Load Workpiece
Position workpiece on the bolster from any of three open sides. The open throat accommodates long shafts, wide plates and irregular shapes. Sensors confirm material presence and proper positioning before cycle start.
3
Press & Form
Ram approaches at fast speed, transitions to controlled pressing speed on material contact. Proportional valves regulate tonnage in real time. Optional dwell holds pressure at bottom for press-fitting, forming or curing as required.
4
Retract & Unload
Ram automatically retracts at high speed. Finished part is removed from the open throat area manually or via automation. Cycle counter increments and the press is ready for the next workpiece immediately.
