AI for crane and rigging companies, tested on quotes and machine files you already closed.

Renting with an operator puts you inside the rule. OSHA's small entity guide to its crane standard, 29 CFR 1926 Subpart CC, says a company that leases a crane and provides the operator must comply, even when the customer's foreman alone supervises that operator. A company that sends no one to the site is not subject to it, though its customer may still ask for written records of past inspections. So every request has to settle early whether the rental is operated or bare. The chair of the Specialized Carriers and Rigging Association's crane group has said crane contracts are usually written for maintained and operated rentals, wording that doesn't apply to bare rental, and the association now gives members a separate guide to those agreements, with insurance, indemnity and liens among its topics.

A customer's first message is short, and your closed jobs show what it became. A plant calls about moving a press. A contractor emails asking for a crane by size. What comes back from your office is a job sheet and quote lines. Twenty to thirty requests your desk already quoted make a complete test, because each one holds the message that started it and the quote your estimator actually sent.

Public buyers show how much a quote has to carry. California's Department of Water Resources buys operated crane rental field division by field division. A San Luis listing posted July 21, 2026 runs by ton class and by hydraulic or lattice boom, asks for at least one ground crew member as rigger or signal person, and wants emergency service around the clock with a four-hour response. A San Joaquin listing posted June 16, 2026 prices straight time, overtime and double time for each crane type, makes accessory load delivery its own hourly line, and expects a bidder within 50 miles of the Bakersfield operations center.

Plant work and site work can fall under different rules. Subpart CC covers cranes used in construction. OSHA's general industry rule for crawler, locomotive and wheel-mounted cranes, 29 CFR 1910.180, has its own inspection schedule and records. The City of Tracy, California, in its April 16, 2026 notice for on-call crane services at water, wastewater and storm facilities, holds equipment to the state Vehicle Code and Cal/OSHA's General Industry Safety Orders. A fleet that sets rooftop units one week and pulls a gearbox from a treatment plant the next may answer to both, depending on the work and the site.

Your customers read that file too. OSHA's guide tells a crane's lessee not to rely on the lessor's word that it complies, and names the most recent monthly and annual inspection reports as one way to check. Without those documents, the lessee needs its own annual inspection, documented, before running the crane. The machine files you already keep show a reviewer what a complete answer looks like.

One limit covers both jobs. The proof of concept never touches your dispatch, rental or maintenance system or a live quote or record. It never picks a crane, plans a lift, reads a load chart for use or decides that a machine is safe to operate. A qualified person on your team plans every lift, and a competent or qualified person performs and signs every inspection. We cite OSHA and state rules so you can recognize your own paperwork, not as legal or engineering advice.
