Truck & Heavy Equipment Inspections

With trucks and heavy equipment comes an additional responsibility: clearing safety inspections on time and on schedule, to make sure your business does not violate any governing laws.

It is certainly an additional task, and a very time-consuming one, that often frustrates new owners who want to concentrate on growing their business.

That is why Custom Truck One Source is here to help take care of annual inspections for their customers!

Three principal annual checks – DoT Inspection, ANSI Inspection and Di-Electric Inspection – are tasks you can safely leave in our capable and experienced hands when you buy trucks and ancillary heavy equipment for your business. We undertake to make sure your equipment is compliant with the laws.

But first, what are these inspections?

# 1: DoT Inspection

In order to ensure that all CMV (Commercial Motor Vehicle) parts and accessories are safe and in good working order, a DoT Inspection is required by the Department of Transportation annually. Once your CMV passes the inspection, you receive a sticker to display on your vehicles to show that they have been vetted and cleared.

Obtaining a DoT inspection is easy and hassle-free because Custom Truck One Source can handle the procedure for you. It shouldn’t have much of an impact on the day-to-day running of your business. We’ll conduct the inspection, install the certification sticker for your CMV and give you a hard copy of the inspection check sheet for your vehicle’s file that must be preserved for a period of 14 months.

# 2: ANSI Inspection

Heavy equipment, such as CMVs with mounted aerial lifts, digger derricks, cranes, pressure diggers, etc. must follow inspection standards set by the ANSI (American National Standards Institute).

To secure maximum protection against falls and accidents, and account for any wears and tears that may render any equipment unfit for service, the ANSI Inspection checks for anomalies like absence or illegibility of markings or tags, unauthorized alteration of parts, evidence of defects, damages, etc.

Gear and equipment should be checked before each use by the operator and formally inspected by qualified personnel at least once a year (or more frequently if required by the manufacturer). Custom Truck One Source is ready to handle your ANSI inspection on your truck-mounted aerial devices.

# 3: Di-Electric Inspection

The Di-Electric inspection verifies the electrical insulating strength in the Fiberglass Reinforced Plastic (FRP) upper and lower booms, bucket, liners, FRP extensions on digger derricks, tool circuits, and upper control system.

Insulated aerial devices protect workers from being electrocuted, and Di-Electric testing is required by law to make sure that the insulating portion of the machine is safe and fully functional. A new piece of equipment has to be Di-Electric tested at the factory in accordance with ANSI requirements to verify insulating rating. Additional tests are performed annually (or more frequently if required by the manufacturer) to confirm the insulating value after units are completed and put into operation.
