Overhead Reach Limit Height Checker

Resolve actual adjustable overhead-task overlap and fixed tasks beyond individually measured comfortable reach; no maximum anatomical reach inference or recommended overhead-work allowance.

Description

Adjustable task heights and measured comfortable reach can share an interval.

Adjustable task heights and measured comfortable reach can share an interval. Fixed tasks above the upper reach limit are a separate check.^[1]

Enter two ordered nonnegative centimeter bound pairs and nonnegative fixed task heights. Return overlap or empty list, inclusive compatibility flag and strict-above-upper fixed-task flags.

When to use Overhead Reach Limit Height Checker

Use Overhead Reach Limit Height Checker when you need to evaluate the supplied records under the calculation and evidence rules below. No anatomical maximum, safe overhead duration or prescribed adjustment is inferred.

Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.

How to use Overhead Reach Limit Height Checker and understand its results

Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.
Enter measuredComfortableOverheadReachBoundsCm, taskAdjustableHeightBoundsCm, fixedTaskHeightsCm using the field table and calculation rules, then run the tool.
Read compatibleAdjustableHeightBoundsCm, adjustableCompatibilityFound, fixedTaskAboveComfortableReachFlags. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
measuredComfortableOverheadReachBoundsCm	Measured comfortable overhead reach bounds cm	list of number	Required
taskAdjustableHeightBoundsCm	Task adjustable height bounds cm	list of number	Required
fixedTaskHeightsCm	Fixed task heights cm	list of number	Required

Enter two ordered nonnegative centimeter bound pairs and nonnegative fixed task heights. Return overlap or empty list, inclusive compatibility flag and strict-above-upper fixed-task flags.

overlap=[max(lower bounds),min(upper bounds)]

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
compatibleAdjustableHeightBoundsCm	Compatible adjustable height bounds cm	list of number
adjustableCompatibilityFound	Adjustable compatibility found	boolean
fixedTaskAboveComfortableReachFlags	Fixed task above comfortable reach flags	list of number

Limitations and assumptions

No anatomical maximum, safe overhead duration or prescribed adjustment is inferred.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use Reach Zone Primary Envelope Radius Checker: A planar reach envelope can exclude tasks both too near and too far. Distances depend on the caller’s measured origin. For a complementary task, use Grip Span Optimal Range Two-Handle Tool Checker: A comfortable measured grip-span interval can overlap an adjustable tool interval. A single shared endpoint counts as compatible.
