Each of the Chicago Dreis & Krump Hydraulic Powered Leaf Brakes were retrofitted with an ISB Merlin 4000 Safety Package mounted vertically to provide protection for the point of operation and a second ISB MX4000 Series Safety light curtain mounted horizontally to protect the operator's legs when the folding beam swings forward.
The Vertical and horizontal Light Curtain Columns are mounted on steel brackets and have built-in protective covers.
The Merlin 4000 is supplied with its Color 7" HMI for easy step by step prompting instructions for the operator.
A custom-built interface was supplied to properly install the safety devices to the machine's existing electrical system.

Making it safe; Two Chicago Dreis & Krump Hydraulic Powered Leaf Brakes recently retrofitted with ISB Merlin 4000 Safety Packages. 

We recently completed installations of Merlin 4000 Systems on two Chicago D&K Hydraulic Powered Leaf Brakes at a plant in Delaware.   What makes these leaf brakes even more challenging to safeguard is that they require a “Smart” safety light to protect the operator’s hands at the point of operation, while still allowing for fabrication of parts with varying side flange heights.  When the part is being bent, we must also ensure that the operator is standing in the proper position so that the folding beam doesn’t strike the operators legs when it swings forward. 

 The Merlin 4000 has features built-in to allow for fabrication of parts on this type of machine with minimal impact on productivity while providing for a completely safe operation.

The ISB MERLIN 4000 is our newest design that is specifically designed to deal with all the challenges of safeguarding a press brake & related fabrication machines such as Folding Machines & Box + Pan Leaf Brakes.  Only the MERLIN concept, pioneered by ISB, can learn each flange profile while making your initial sample part and creates a window exactly the proper size and location required for each specific cycle.  This opening may change from stroke to stroke automatically, completely determined by our processor, not your operator or set-up personnel.    The end result is that you have the most productive and safest system that operates exclusively with ISB’s MX Safety light curtain columns, that are CE certified by TUV for Type 4 Functional Safety.  All wiring boxes are UL listed.

The Merlin 4000 has become the ultimate product for guarding Press Brakes, regardless of machine type,  tooling, or material type and thickness.
