Overview
The Ermak CRV Press 3100-220 is a heavy-capacity hydraulic CNC press brake from Ermaksan's CRV series, delivering 220 tonnes of pressing force across a 3,100 mm working length. Designed for structural steel fabricators, heavy plate forming operations, and general fabrication shops requiring high-force bending at competitive pricing, the CRV series occupies the upper tonnage tier of Ermaksan's hydraulic press brake lineup, filling applications that exceed the capacity of the mid-range CYB and Falcon Bend series.
The CRV 3100-220 uses a conventional synchronised hydraulic drive system with electro-hydraulic proportional valve control for Y1/Y2 cylinder synchronisation. The CNC system — typically a Delem DA-66T or equivalent Cybelec control — provides graphical bend programming, stored program management, and back-gauge sequencing for repeat-job production efficiency. While the CRV does not include the servo-hydraulic energy recovery of Ermaksan's Falcon Bend or Servo Bend series, it delivers the raw bending force needed for heavy structural and plate work at a fraction of the cost of comparable Western European machines.
The CRV's frame is a heavy welded steel monoblock construction, stress-relieved after fabrication to minimise residual stresses that could affect long-term frame parallelism. The press beam and table are engineered with sufficient stiffness to maintain acceptable ram-to-die parallelism at maximum pressing force over the full 3,100 mm working length. A mechanical or hydraulic crowning system compensates for beam deflection during bending to maintain angle consistency across long workpieces.
Ermaksan supports the CRV series with standard European-style tooling compatibility, allowing shops to use Wila, Rolleri, or Trumpf-style punches and dies alongside the machine's native tooling. The CRV 3100-220 ships with a motorised multi-axis back-gauge as standard, with options for additional Z-axis and R-axis configurations to accommodate complex part families.
For fabricators who need 220 tonnes of bending capacity at 3,100 mm working length and prioritise total cost of acquisition over the energy efficiency benefits of servo-hydraulic drives, the CRV 3100-220 delivers a well-built, productively capable machine supported by Ermaksan's growing European and export distribution network.

Strengths & Limitations
Strengths
- 220-tonne capacity at 3,100 mm handles heavy structural steel plate bending at a substantially lower price than European equivalents
- Delem DA-66T control provides 3D graphical programming and offline simulation for efficient setup on complex part programs
- Standard European tooling compatibility allows use of existing Wila, Rolleri, or Trumpf-style tooling without adapter kits
- Heavy welded frame construction with stress relief provides long-term dimensional stability for high-force production bending
- Crowning system compensates for press beam deflection to maintain angle consistency across the full 3,100 mm working length
Limitations
- Conventional hydraulic drive is less energy-efficient than servo-hydraulic equivalents, with higher power consumption on high-cycle schedules
- Brand recognition in North American markets remains lower than European competitors, which may affect resale value and financing availability
- Service support outside Europe and the Middle East can involve longer lead times for on-site technical assistance

Frequently Asked Questions
01
The CRV series uses a conventional fixed-displacement hydraulic drive, while the Falcon Bend upgrades to a servo-hydraulic system. The CRV offers higher maximum tonnage options (220 tonnes and above) at a lower purchase price per tonne of capacity, making it the preferred choice for heavy structural work where raw force is the priority. The Falcon Bend is better suited to medium-capacity precision applications where energy efficiency and faster cycle times justify the price premium.
02
At 220 tonnes over 3,100 mm, the CRV can bend mild steel plate up to approximately 15–18 mm across the full working length, and up to 25 mm on shorter bends concentrated over a portion of the working length, depending on material grade and bend radius. High-strength steel capacities are reduced proportionally. Ermaksan's bending force charts should be used to confirm capacity for specific applications.
03
The CRV 3100-220 includes a crowning compensation system to counteract press beam deflection under bending load. The crowning configuration — mechanical wedge or hydraulic — varies by specification; buyers should confirm the specific crowning system included with their machine at time of order. Proper crowning setup is essential for achieving consistent angles across the full 3,100 mm working length at high tonnage.
04
The Delem DA-66T supports direct import of bend programs from Delem's Profile-T offline programming software, allowing complex parts to be programmed at a workstation and downloaded to the machine. The control also supports 3D simulation for interference checking before running a program on the machine, reducing costly collisions during setup.
05
The CRV 3100-220 typically ships with a 4-axis motorised back-gauge including X (depth), R (height), and Z1/Z2 (independent finger positioning). This configuration supports the majority of complex part families encountered in structural fabrication. Additional axes or power-assisted finger options may be specified for shops handling very large or heavy workpieces where manual part positioning is impractical.
