Break Test Bed

BReak Test Beds

Need to break a specimen?

Our Break Test machines are used by wire rope manufacturers to break test wire rope specimens during the manufacturing process. For quality control and verification, it is necessary for wire rope manufacturers to break test samples of their products to ensure the breaking force is within their published specifications.

The wire rope sample can be as short as a few inches.

Pre-Stretch Bed

Pre-Stretch Beds

Need to pre-stretch wire rope?

Chant Engineering’s Pre-Stretch Beds are used by wire rope manufacturers and fabricators to pre-stretch wire rope before shipment to customers. Pre-stretching seats the individual wires in the rope under load to minimize further stretching of the final product.

Chant Pre-Stretch Beds utilize two hydraulically controlled Chant Wire Rope Grips. One grip is fixed (does not move). The other grip is mounted on the framework, which is then moved by hydraulic cylinders.

Tugger Winch Tester

winch/Tugger Tester

Static and/or Dynamic Testing

This unit comes complete with a heavy-duty frame, an integrated t-slot table for securing different sized winches to the frame and a stand-alone Hydraulic Power Unit (HPU).

Proof Test Machines Upgrades and Options

Upgrades & OPTIONS

We can fix, upgrade, or retrofit any machine

Chant Engineering offers many options to make your testing easier, more accurate and more complete.

We can also upgrade your existing machine with additional functionality and  upgrade it to meet today’s ASTM-E4 accuracy testing standards.

Typically, old machines are reading hydraulic pressure and converting this to pounds of force. Chant can remove the old pressure transducer, and add a load cell to read the lbs. of force.  We can also add our specialized software for additional data acquisition and machine functionality for a fraction of the cost vs. building a new machine.
