Construction (29 CFR 1926)

Free Fall and Controlled Lowering

Verified vs OSHA sources · 2026-10-05

29 CFR 1926.1426

29 CFR 1926.1426 restricts free fall and requires controlled lowering on cranes. Using equipment in which the boom is designed to free fall (a "live boom") is prohibited in specified dangerous circumstances: such as when workers are in the fall zone, when personnel are being hoisted, or near power lines. The section also limits load-line free fall and requires controlled load lowering so loads and booms stay under powered control.

What 29 CFR 1926.1426 requires (plain English)

29 CFR 1926.1426 governs "free fall and controlled load lowering" on cranes. Free fall is when the boom or the load descends by gravity, the brake is released and it drops, rather than being lowered under power through the hoist mechanism. Free-fall (or "live boom") capability exists on some cranes, particularly older friction machines, and is faster but far less controllable than powered lowering.

The section prohibits the use of equipment in which the boom is designed to free fall (a live boom) in each of several specified circumstances, including where an employee is in the fall zone of the boom or load, where employees are being hoisted (personnel lifting), where the crane is being used near power lines, and in other high-consequence situations. The idea is that where a loss of control would be catastrophic, the boom must be under powered control, not free-falling.

1926.1426 also addresses load-line free fall and controlled load lowering, restricting when the load line may free fall and requiring that certain lowering be done under power. Together these rules ensure that in the dangerous situations (over people, hoisting personnel, near energized lines) the crane's boom and load are lowered in a controlled, powered manner rather than dropped by gravity.

What the source requires, in summary

Common Crane Free Fall violations

Deficiencies OSHA cites under 29 CFR 1926.1426 include the ones below, in no particular order. Distinct deficiencies can be cited as separate items, and each serious item carries up to $16,550 (2026). Broader per-instance stacking exists but is a discretionary, case-by-case OSHA enforcement policy, not an automatic multiplier.

Using a live-boom (free-fall) crane while hoisting personnel (1926.1426(a)).
Free-falling the boom with an employee in the fall zone (1926.1426(a)).
Using a live-boom crane near power lines in prohibited conditions (1926.1426(a)).
Load-line free fall where controlled lowering is required (1926.1426(d)).
Not using controlled load lowering in the specified situations (1926.1426).

Free fall is fast, but it is exactly what you cannot use where a loss of control would kill

Some operators favor free fall (live boom, or free-falling the load line) because it is quick and can feel efficient for certain routine tasks. 1926.1426 does not ban free fall outright, but it prohibits it in the situations where losing control would be catastrophic, when an employee is in the fall zone of the boom or load, when personnel are being hoisted, when working near power lines, and other specified conditions. The mistake is treating free fall as a normal operating mode everywhere. In the dangerous scenarios, the boom and load must be under POWERED control (controlled lowering), not dropped by gravity. Using a live-boom crane to lift people, for instance, is flatly prohibited.

What OSHA inspectors look for

A compliance officer checks whether a live-boom (free-fall) crane is being used in any of the prohibited situations, and whether load lowering is controlled rather than free-falling. Using a friction/live-boom crane to hoist personnel or over workers, or free-falling loads, are the findings.

Example: how a violation is cited

A contractor uses an older friction crane with a free-fall boom to hoist a personnel platform; the boom is not under continuous power and a control problem develops. OSHA cites 1926.1426 for using a live-boom crane to hoist personnel, a prohibited free-fall situation, with penalties from $16,550.

Determine whether the crane has free-fall (live-boom) capability.
Do not use a live boom where an employee is in the fall zone or personnel are being hoisted.
Do not use free fall near power lines in the prohibited conditions.
Use controlled load lowering (under power) where free fall is not allowed.
Restrict load-line free fall to permitted situations only.
Train operators on when free fall is prohibited and controlled lowering is required.

2026 penalties for 29 CFR 1926.1426

Maximums set by 29 CFR 1903.15(d). 2026 amounts unchanged from 2025 (no CPI adjustment; OMB M-26-11). Not an increase. The 2025 OSHA penalty levels remain in effect for 2026; OSHA made no inflation adjustment for 2026. 29 CFR 1903.15 identifies January 15, 2025 as the effective reference for these amounts, while OSHA's public penalties page currently references penalties assessed after Jan. 15, 2026.

Violation type	Minimum	Maximum	When it applies
Serious	$1,085	$16,550	Substantial probability of death or serious physical harm.
Other-Than-Serious	$0	$16,550	Relates to safety/health but unlikely to cause death or serious harm.
Willful	$11,823	$165,514	Intentional, knowing, or voluntary disregard of the requirement.
Repeated	$4,256	$165,514	A substantially similar violation cited within the last 5 years.
Failure to Abate	None	$16,550/day	up to $16,550 per day; total capped at 30x the daily amount (FOM Ch.6)

Free-fall violations are cited when live-boom cranes are used in prohibited situations. Serious violations reach $16,550 and willful or repeat violations $165,514.

Maximums and the willful minimum are set by 29 CFR 1903.15(d); the serious and repeated minimums are OSHA policy floors from its annual penalty adjustment memo. OSHA applies gravity-based and size, good-faith and history reductions (FOM CPL 02-00-164 Ch.6). Estimates only, not legal advice.

The business case for Crane Free Fall compliance

Free fall means the boom or load descends by gravity, released from the brake, rather than being driven down under power: fast and far harder to control. In the wrong situation (over workers, hoisting people, near power lines), a free-fall boom or load can drop or swing catastrophically. 1926.1426 bans free fall exactly where the consequences are deadly and requires controlled lowering, keeping the crane under powered control when it matters most.

Frequently asked questions about 29 CFR 1926.1426

What is a 'live boom' on a crane?

A live boom is a boom designed to free fall, to descend by gravity when the brake is released, rather than being lowered under power through the hoist mechanism. It is faster but far less controllable, and is more common on older friction cranes. Under 1926.1426, using a live boom is prohibited in specified dangerous circumstances.

When is crane free fall prohibited?

Under 1926.1426, free fall of a live boom is prohibited in several high-consequence situations, including when an employee is in the fall zone of the boom or load, when employees are being hoisted (personnel lifting), and when the crane is used near power lines, among others. In those situations the boom and load must be under powered, controlled lowering.

What is controlled load lowering?

Controlled load lowering means lowering the load under power through the hoist mechanism, with the drive train engaged, rather than letting the load line free fall by gravity. 1926.1426 requires controlled lowering in the situations where free fall is prohibited, so the load stays under the operator's powered control throughout the descent.

Can a free-fall crane be used to lift people?

No. Under 1926.1426, using equipment in which the boom is designed to free fall (a live boom) is prohibited while employees are being hoisted. Personnel hoisting demands maximum control, so a live-boom/free-fall configuration cannot be used for it: this connects to the strict personnel-hoisting rules in 1926.1431.

Regulatory history of 29 CFR 1926.1426

The free-fall and controlled-lowering restrictions in 1926.1426 took effect with Subpart CC on November 8, 2010 (75 FR 47906). As cranes moved from older friction (free-fall-capable) designs toward hydraulic powered control, the standard prohibited free fall in the high-consequence situations (over people, hoisting personnel, near power lines) where controlled lowering is essential.
