A crane, a forklift, a boom lift, and an excavator all have something a ladder does not: a serial number, a service history, an inspection cycle, and a certificate with a date on it. Every one of those can be demanded in a lawsuit, and every one of them points at a company that is not your employer.
A worker struck, crushed, pinned, or run over by equipment on a Los Angeles job site has claims that run on the certification and inspection rules in Title 8, the California workplace safety regulations, and on who owned and controlled the machine. Highway collisions involving haul trucks off site belong on our Los Angeles truck accident page.
How equipment injuries happen on site
Two mechanisms account for most of it. A struck-by injury is contact from a moving object: a swinging load, a dropped bundle, a reversing loader, a failed rigging component. A caught-in-or-between injury is compression between two objects or inside machinery: a worker pinned between a forklift mast and a wall, or between a swinging counterweight and a fixed structure.
Two terms of art follow those mechanisms into every deposition, the sworn questioning before trial. The swing radius is the area a rotating machine sweeps, and pinch points inside it are why counterweight zones are supposed to be barricaded. A signal person directs a lift when the operator cannot see the load or the landing zone, which is when a general contractor's coordination role becomes an issue of control.
Who has to be certified in California
Title 8 section 5006.1 permits an employer to allow only operators holding a valid certificate of competency to run a covered crane, and requires that the crane operator testing organization providing the certification be accredited by an approved nationally recognized accrediting agency. The section exempts mobile cranes with a boom length under 25 feet or a rated capacity under 15,000 pounds, electric line truck operators running digger derricks, and marine terminal operations.
Section 3668 does the same work for powered industrial trucks, which is the regulation's name for forklifts. The employer must ensure each operator is competent, demonstrated by successful completion of training and evaluation combining formal instruction, practical training, and evaluation of performance in the workplace. Performance must be re-evaluated at least once every three years, and the employer must certify the training with the operator's name, the date of the training, the date of the evaluation, and the identity of the persons who performed them.
That certification record is the first document to request, because it is short, dated, and either exists or does not. Section 3668 also requires refresher training when an operator has been seen operating unsafely, has been involved in an accident or a near miss, has failed an evaluation, is assigned a different type of truck, or when conditions in the workplace change. An accident record with no refresher training after it is a fact a jury understands immediately.
| Equipment | Requirement | Section |
|---|---|---|
| Covered cranes | Operator holds a valid certificate of competency | 5006.1 |
| Cranes and derricks over 3 tons | Annual test and examination, certificate issued | 5021 |
| Forklifts and powered industrial trucks | Training, evaluation, and certification record | 3668 |
| Forklift operators | Performance re-evaluated at least every 3 years | 3668 |
The crane certificate names an outside company
The certificate names an outside company, and that is the point. A licensed certificating agency that examined the crane and passed it weeks before a boom failure becomes a defendant with its own insurance, its own inspection notes, and its own reason to explain what it looked at. Your employer's exclusive remedy shield, the rule that workers' compensation is your only claim against your employer, does nothing for any of them.
Who is liable when the machine fails
- The manufacturer, for a design or manufacturing defect or a failure to warn, in an ordinary product liability claim that does not require proof of carelessness.
- The rental yard or equipment owner, for supplying a machine in unsafe condition, for skipping maintenance, or for delivering it without the required certificate.
- The hirer that supplied the equipment, meaning the company that hired the contractor doing the work, under California jury instruction CACI No. 1009D, which reaches a hirer who negligently provided unsafe equipment that contributed to the injury even where the work itself was fully delegated.
- The general contractor, where it controlled the lift plan, the signal protocol, the ground conditions, or the exclusion zone, and exercised that control badly, under CACI No. 1009B.
- The operator's employer, when the operator worked for a different company than you did, which makes an ordinary negligence claim available against that company.
- The maintenance or certification contractor, for an inspection or repair performed without care.
| Record | What it shows | Who usually holds it |
|---|---|---|
| Annual crane certificate | Whether the machine was fit to lift | Owner or certificating agency |
| Operator certificate of competency | Whether the operator was qualified | Operator's employer |
| Forklift training certification | Names, dates, evaluator, refresher history | Operator's employer |
| Service and repair history | Known defects and deferred maintenance | Rental yard or owner |
| Daily equipment inspection sheets | What was reported and ignored | General contractor or owner |
Preserving the machine before it disappears
Rented equipment goes back. Damaged equipment gets repaired, because it is worth money and the yard wants it earning. Once a boom is straightened or a hydraulic line replaced, the physical evidence of what failed is gone and the case becomes an argument between engineers about photographs. A written demand to your employer, the general contractor, the equipment owner, and the rental company that the machine, its data recorder, and its service file be held changes what can be proved.
Ask for the serial number on the day it happens. Late-model equipment often carries telematics, onboard data systems, that log engine hours, load moment indicator alarms, and fault codes, and that data is overwritten or purged on a schedule nobody will pause voluntarily.
When the equipment was not the problem
- The machine was maintained, certified, and working. A product claim needs a defect, and a claim against the lessor, the company that rented out the machine, needs an unsafe condition. A bad outcome alone is not either one.
- The operator and the rigger both worked for your employer, on a machine your employer owned, on a site where nobody else directed the lift.
- The general contractor wrote a lift plan and never enforced it. Under the Sandoval case, a hirer must actually exercise the control it retained, so an unused plan is closer to no control than to bad control.
- The equipment was returned and repaired before anyone inspected it, which does not end the claim but moves it onto records and witnesses alone.
- You were the equipment owner's own employee, in which case that company is your employer and the exclusive remedy rule applies to it.
Where an equipment case starts
An equipment case starts with three pieces of paper: the certificate for the machine, the certificate for the operator, and the service file. If any of the three is missing or lapsed, the company that should have held it is in the case, and it is not your employer. If all three are in order, the case moves to the lift plan, the signal person, the ground conditions, and who was directing the work.
Send the preservation demand this week, get the serial number, and get treated. How the recovery is later split with the workers' compensation insurer is covered on third-party claims and workers' compensation, the fall hazards that ride along with lift work are on falls from heights and scaffolding, and the full liability framework is on our Los Angeles construction accident lawyer page. A crushing injury that takes a limb belongs with our catastrophic injury practice.
Give us the machine, the company that owned it, and the date. We will send the preservation letters. No fee unless we recover.
