Proof Tests

A proof load test is performed on lifting and anchoring equipment to ensure they can withstand the design load without failure.

Proof load tests are performed when lifting equipment is new, as well as periodically.

Crane scales, dynamometers, hook scales and hoist scales that are used for below hook weighing are often used also for proof test applications, hoist and crane load testing as well as anchoring point proof testing.

Proof load test is an important safety practice and its purpose is to prevent equipment or structure failure,

Ron Crane Scales and dynamometers are especially suitable for proof load test:

Lightweight design enables portability

High accuracy: 0.1% f.s.

Standard remote display allows the user to read the result from a safe distance

Small dimensions enable low headroom loss

2000h battery life

Peak hold (max value)


Data logger

Fatigue rated load cells

40 years of experience
