Crane Pre-Use Inspection Checklist (OSHA & DGMS Compliant)

A crane must be inspected before every shift it will be used, by a competent person, before the first lift. This is the pre-use, pre-shift, or frequent inspection required under OSHA 1926.1412(d) and reflected in DGMS expectations for lifting equipment on Indian sites. Beyond the daily check, there are two more tiers: a documented monthly inspection by a competent person covering structural members, sheaves, and drums, and a comprehensive annual inspection by a qualified person that includes non-destructive testing, load testing, and full recalibration of safety devices. A thorough pre-use inspection takes about 15 to 30 minutes — overhead cranes are quicker, while mobile cranes take longer because of ground conditions, outriggers, and full wire rope travel inspection.

The seven critical systems are: hooks and hook block (cracks, throat opening, safety latch, twist); wire rope (broken wires, kinks, bird-caging, corrosion, seating); controls and hydraulics (lever return-to-neutral, function tests, leaks); brakes (hoist, swing, boom, and travel brakes holding without drift); load chart and structure (chart present and legible, correct counterweight, boom and pins sound); outriggers and ground (full extension, proper pads, firm ground, tyres or tracks); and safety devices (anti-two-block, load moment indicator, boom angle indicator, limit switches, emergency stop). Of these, wire rope is the most critical and most commonly cited defect, because a rope failure under load means a dropped load.

Under OSHA criteria, a running wire rope must be removed from service if it has six or more randomly distributed broken wires in one rope lay, or three or more broken wires in one strand in one lay. It must also be rejected for kinking, crushing, bird-caging, core protrusion, significant diameter reduction below specification, heat damage, or severe corrosion. The most common inspection mistake is checking only the visible section of rope between the boom tip and hook — the full travel of the rope must be run out and inspected slowly, because broken wires are easy to undercount. Wire rope is not an item to watch for a few days; once it hits a rejection threshold, it must be replaced before the next lift.

The pre-use inspection must be done by a competent person — someone trained to recognise crane hazards and authorised to take corrective action. For daily checks this is typically the crane operator running the machine that day, or a designated equipment person who covers several cranes on a large site. The competent person does not need to be a certified third-party crane inspector for the daily check — that higher qualification is required for the comprehensive annual inspection, which must be done by a qualified person. The critical principle is that the competent person has the authority to stop a lift: if a critical defect is found, the crane is removed from service until repaired and re-inspected, and the project schedule does not override that decision.

Crane inspection records are central to how compliance is judged — in an audit or after an incident, the absence of a record is treated as the inspection not happening. A digital checklist on HVI ensures the inspection actually takes place and is documented properly: it requires a photo of the wire rope, hook, and safety devices on every shift, captures a competent-person digital signature with GPS and timestamp, and cannot be closed with a critical item unresolved. Critical defects trigger an instant alert and lock the crane out of service. The records are retained automatically for the required periods — ongoing for shift checks, three months for monthly, and twelve months or more for annual — and can be pulled up instantly for an OSHA, DGMS, or client audit. This turns the checklist from a box-ticking exercise into genuine, defensible proof of safe lifting.
