Crane Load Testing in Nevada: When and How It’s Done

Crane Load Testing in Nevada: When You Need One and What Happens on Test Day

A crane load test is one of those jobs people put off until a deadline forces it: a new crane that needs to go into service, an insurance audit, or a customer asking for paperwork. Then everyone wants it done this week.

Here is how crane load testing in Nevada works, when the federal rule actually requires one, and what to expect on test day so it goes smoothly.

When Does Nevada OSHA Require a Crane Load Test?

Nevada runs its own OSHA state plan, and for overhead and gantry cranes it applies the federal standard, 29 CFR 1910.179.

Section (k) of 1910.179 covers testing:

  • Operational tests: New and altered cranes must be tested before first use. The test covers hoisting and lowering, trolley travel, bridge travel, and limit switches, locking and safety devices.
  • Rated load test: Test loads cannot be more than 125 percent of the rated load unless the manufacturer recommends otherwise.
  • Reports: Test reports have to be on file where they are readily available to appointed personnel.

There is also a specific case in section (l): if a hook is repaired by welding or reshaping, which is not generally recommended, it must be tested to the (k)(2) load requirements before going back into use.

What About an Existing Crane?

Common Reasons to Schedule a Load Test

  • A new crane before first use
  • A crane that was altered, such as a hoist change, capacity change or span change
  • A crane moved to a new building and reinstalled
  • A hook repaired by welding or reshaping
  • Insurance or corporate safety program requirements
  • Documentation for a customer audit

The Hoist Limit Switch Test

1910.179 spells this one out. The trip setting of the hoist limit switches is found by running an empty hook into the switch at increasing speeds, up to the maximum speed. The switch has to trip under all conditions in time to keep the hook or hook block from contacting any part of the trolley.

What Happens on Test Day

1. Pre-Test Inspection

Before any weight is lifted, the technician inspects the crane: structure, hook, rope or chain, brakes, wheels, controls and electrical. A crane with a defect does not get tested until it is fixed.

2. Operational Tests

Each motion is run without load: hoisting and lowering, trolley travel, bridge travel. Limit switches and safety devices are checked.

3. Rated Load Test

The test weight is rigged and lifted. The technician watches for brake slip, abnormal noise, structural deflection and control problems while moving the load through each motion.

4. Post-Test Inspection and Report

After the test, the crane is inspected again and the results go into a written report for your files.

Test Weights: Solid or Water

Test weight is often the hardest part to arrange.

Solid weights are steel or concrete blocks with known weights, brought to the site on a truck.

Water weight bags are filled on site and weighed with a load cell. They are handy for heavy capacities or tight access.

CraneVeyor performs 125 percent load tests and keeps test weights in house.

What If the Crane Fails the Test?

It happens. A brake that slips under load, a limit switch that trips late, or excessive deflection all mean the crane does not pass that day. The crane stays out of service until the problem is fixed, and then the affected part of the test is repeated.

That is one reason I like to see a pre-test inspection a week or two before test day on an older crane. Finding a worn brake ahead of time lets us bring the parts and avoid a second trip.

Common Reasons a Test Gets Stopped

  • Hoist brake slipping or overheating
  • Hook, rope or chain damage found during the pre-test inspection
  • Limit switch not tripping reliably
  • Loose bolts or cracked welds on the end trucks or girder connections
  • Electrical faults that show up under load

How to Prepare Your Site

  • Clear the floor under the full crane travel area
  • Arrange a forklift or other way to unload weights, if needed
  • Plan around production. Nothing else moves on that runway during the test
  • Have someone available who can make shutdown decisions
  • Gather old inspection and test reports

Frequently Asked Questions

When is a crane load test required in Nevada?

Under 29 CFR 1910.179, which Nevada OSHA enforces, new and altered cranes must be tested before first use. A hook repaired by welding or reshaping must also be load tested before further use.

How much weight is used in a crane load test?

Under 29 CFR 1910.179(k)(2), test loads cannot be more than 125 percent of the crane’s rated load unless the manufacturer recommends otherwise.

What is included in a crane operational test?

Operational tests cover hoisting and lowering, trolley travel, bridge travel, and limit switches, locking and safety devices.

Do existing overhead cranes need yearly load tests in Nevada?

Federal rules rely on frequent and periodic inspections for cranes in service rather than scheduled load tests. Many owners still test on a schedule for insurance or company safety programs.
