Testing and Inspections

Annual Crane Testing

We now perform the needed safety tests on:

• Utility Bucket Trucks / jib Cranes
• Digger Derricks / Aerial Lifts
• Man-Lifts / Overhead Cranes
• All Cranes Rated up to 100 Tons

We are federally and state regulated to perform these tests. Our forms we use and costs to perform these tests are a phone call away. Please call our staff with your questions. We are very competetive on our pricing, but our service is second to none.

Hi-Pot Testing

The term hi-pot testing is a contraction for high potential, which means high voltage testing. Hi-pot testing has more commonly been further shortened to hipot testing which become a widely accepted term for the process for applying high voltage to a device in order to determine the status of its electrical insulation. Although hi-pot is a commonly used word, there are many it has many terms with similar or identical meanings. Voltage withstand testing, dielectric strength testing and insulation breakdown testing and are popular terms synonymous with hi-pot testing.

Hi-pot testing uses either an AC or DC stimulus voltages dependent on the test specification. The hi-pot test is the most popular form of electrical safety testing. Products which operate from line voltage, often require production line hi-pot testing on a 100% basis. Besides hi-pot testing, ground bond testing and insulation resistance testing are also often required. The test voltage for hi-pot testing is usually specified by the applicable safety standard. As a general rule, the hi-pot test voltage is twice the line voltage plus 1000 volts. Typically hi-pot testing is conducted for a specified time period, for example 1 minute. Many times standards will permit a reduction of the hi-pot testing period, to as little as one second, when the test voltage is increased.

ANSI/SIA A92.2-2001 & OSHA CRANE COMPLIANCE LAWS STATE:
8. Responsibilities of Owners
       8.1 General responsibilities. Each owner SHALL comply with the requirements of this section. The following responsibilities pertain to the owner's inspection, testing, maintenance, modification, training, and transfer of ownership. These activities SHALL be performed by a qualified person(s).
       8.2 Inspection and Testing Classifications
               8.2.1 Initial Inpection and Test. Prior to initial use, all new or modified mob SHALL be subject to inspections and tested to ensation by the manufacturer, the installer or an equivalent entity(s), meets this requirement.
               8.2.2 Regular Inspection and Tests. The Inspection procedure for mobile units is divided into two classifications based upon the intervals at which inspections and tests SHALL be performed. Intervals SHALL be set by the owner in accordance with the manufacturer's recommendations. Such intervals are dependent upon component function and exposure to wear, deterioration and other agents which adversely affect component life. Two classifications are designated:
Frequent Inspection and Test: Daily to monthly interviews
Periodic Inspection and Test: One to Twelve month intervals.
