Steel Crane Test Weights and Proof Load Testing
Hydro-Wates® provides crane, hoist, and beam proof load testing services using steel test weights in applications where low headroom, restricted access or limited test area prevent the use of water test weights. In many cases, they can be more economical than using water test weights, particularly for smaller machines. Steel test weights for proof load testing are well suited for testing the following lifting appliances:
- Low headroom cranes
- Small overhead hoists running on I-beam trolleys
- Small jib cranes
- Cranes located in confined spaces
- Building elevators
- Construction elevators
- Manlifts
- Forklifts
Hydro-Wates® rents steel test weights and provides on-site proof load testing. The weights are not sold, so quote requests cover rental and on-site service only.

Steel Test Weight Inventory and Certification
Hydro-Wates® maintains an extensive rental inventory of steel test weights, with carrier baskets and lift stands. Our individual steel test weights range in size from 25 lbs up to 2,500 lbs, with the larger weights configured to enable stacking on lift stands.
All of our weight-carrying stands and baskets have been designed and developed by qualified experts and are provided with extensive certification packages. All weight-carrying appliances have been proof load tested to a minimum of 200% of the working load limit (WLL). Each individual test weight can be provided with a scale weight certificate traceable to ASME and NIST standards.
Advantages of Steel Test Weights for Crane Load Testing
- Low working height to enable use in limited headroom applications
- Proof load tested carrier baskets and lift stands to ensure operator safety
- Compact and capable of being moved into tight spaces, using rollers, if necessary
- Can be lifted using shackles and other standard rigging hardware
- Stackable in capacities up to 10 tons
- Smaller test weights (50 lb) can be hand-carried by technicians into restricted areas
Our steel test weights are suitable for use in many industries, including oil & gas, maritime, power generation, construction, and military. We can also design, build, and fabricate custom lift frames to suit your very specific project application.
Steel Test Weights vs. Water Test Weights
Steel test weights fit jobs where low headroom, restricted access, or a limited test area rule out water test weights, and they often cost less on smaller machines. Where space allows, water test weights may be the better fit for larger lifts. Hydro-Wates helps match the test method to each crane, hoist, or lift.
