Staying on schedule

Heavy Lifting Test Device

All too often, operators must test lifting equipment and tools once they are installed alongside other equipment. With everything in its final configuration, there is significant pressure to ensure things go smoothly. So Mammoet created the Heavy Lifting Test Device.

Straight to work

Accurately testing high-capacity equipment is a vital part of any heavy lifting project, in order to guarantee quality and safety.

Even when testing goes perfectly, it is time-consuming and occupies key equipment such as cranes, crane ships, ballast and long slings - delaying project work. When tests do not go as planned, there can be a significant impact on the schedule.

Mammoet's testing device can test high-capacity equipment to high loads with low risk and minimal impact to operations. As well as removing the risks of testing components in their final setup and layout, the testing device allows other activities to continue simultaneously by freeing up equipment to be used elsewhere on a project. It also removes the need for time-consuming activities like rigging blocks and tools.

Mammoet aims to play an important role for our customers in realizing efficiencies and optimizing projects to ensure the maximum return on investment and safety.


  • Hook blocks
  • Shackles
  • Shackle connections
  • Three or four-jump slings
  • Other specialist lifting tools

Testing safely away from live work

The testing device uses specifically designed connections, engineered to directly match each piece of equipment to its purpose.

It can simulate lifting angles from 30 to 60 degrees, ensuring tests reflect the equipment's working environment. With digital readings and recordings aligned with various international marine warranty survey requirements, the testing device provides accurate testing for controlled loads.

The device can test equipment in various configurations. Loads can be gradually increased according to your test protocols, up to 6,000t. The system can perform tests at Mammoet’s waterside yards in the Netherlands, or be shipped to site for on-site testing.
