Horizontal Test Bed with Grip

Mobile Test Beds

All Chant Engineering Mobile Test Beds are designed for on the job site testing. By bringing the machine to your customer’s site, you eliminate shipping costs, downtime and employee expense.

This is a value added service for your customers.

Pre-Stretch Test Beds

Chant Engineering 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 Engineering 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.

Vertical Test Beds

Chant manufacturers Vertical Test Beds in a variety of sizes and capabilities to test slings, lifting devices and chain hoists.

  • Small Capacity (5K-40K)
  • Medium Capacity (50K-100K)
  • Large Capacity (100K+)
  • Vertical Testing Towers

Custom Test Beds

Need a custom made test bed? We have the solution for you! Our company slogan is: “If You Can Imagine It…We Can Build It!”

Chant Engineering has extensive experience designing and manufacturing Custom Test Beds. One of the strengths that separates Chant Engineering from our competitors, is our extensive in-house engineering capabilities.

Break Test Machines

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.

Test Bed Upgrades and Options

Chant can customize any machine. We offer additional upgrades, options and customization. Chant Engineering can provide design and engineering solutions for your specific testing environment based on your project needs and specifications.


Chant Engineering can upgrade your existing old Test Beds to meet today’s ASTM-E4 accuracy testing standards. Typically, old machines are reading hydraulic pressure and converting this to pounds of force.

This method cannot take into account the internal friction of the hydraulic cylinder seals and thus can be extremely inaccurate.If your machine is in good working order, Chant Engineering can provide a complete load cell, digital indicator, and software package to bring your machine up to date.


You can add optional items to your test bed project, a few of those items are:

  • Cycling Control
  • Elongation Management
  • Low Load Cylinder
