01 Hand lift check

Is this box too heavy to lift this way?

Eight answers give the recommended weight limit for one two-handed lift, using the NIOSH Revised Lifting Equation. The answer says which part of the lift costs the most, and what to change.

The load

Load weight

Weigh it or read the case label.

Grip

Where the hands are at the start

Reach out from the ankles

Midpoint between the ankles to the hands.

Hand height

Floor to the hands. Knuckle height is about 30.

Vertical travel

Start height to finish height.

Twist

0 = straight ahead; 90 = load ends up beside you.

How often

Lifts per minute

Work spell

Worked example: 33 lb case off a low pallet onto a bench

Caution: change something

1.99Lifting Index

16.6lb recommended limit

01.0 limit3.0

Above 1.0 the risk of a back injury goes up for some workers. Redesign before it becomes routine.

Where the limit goes

Multipliers, 1.00 = no reduction
Reach HM	0.63
Start height VM	0.87
Travel DM	0.88
Twist AM	0.86
Pace FM	0.84
Grip CM	0.95

Biggest gain: Reach. Bring the load closer: remove the reach (lower the barrier, use a side door, slide it to the edge before lifting).

Keep this check

Save it in a private Lift Book (no account, no email) and print it as a job card for the crew.

Free book keeps 5 checks. Lift Pass keeps 500, adds the binder print and CSV export: $1.95 a month or $19.50 a year, free during preview.

What the equation covers

Two-handed lifting or lowering, standing, in a normal workplace, of a load that does not shift. It does not cover one-handed lifts, lifting while seated or kneeling, carrying, pushing or pulling, slippery floors, very hot or cold work, or people with an injury. Limit = 51 lb × reach × height × travel × twist × pace × grip.
