ALSGN-004

Draw attention to a crane overhead with this DANGER — CRANE OVERHEAD sign with a red upward arrow. The design has an OSHA danger header with white DANGER lettering inside a red oval on black, plus bold black CRANE OVERHEAD wording on a white panel. The arrow appears to the right of the wording.

Size and material options

  • Stock size: 18 inches wide × 12 inches tall.
  • Laminated vinyl decal: SKU ALSGN-004.
  • Aluminum sign: SKU ALSGN-004-12x18-Aluminum.

The vinyl option is an adhesive decal for a suitable surface; the aluminum option is a rigid sign. Both stock options carry the same wording and arrow design. Other sizes are available by special order; contact us to discuss your requirements.

What the upward arrow means

The red arrow points upward to draw attention to the crane overhead. It is part of the hazard warning, not a crane travel-direction marking or an instruction to raise a load. Keep the design upright so the arrow retains its intended upward orientation.

Placement and mounting

As general guidance, choose a visible fixed location where people approaching the crane operating area can read the warning before entering. Follow your facility’s procedures and equipment manufacturer’s label-location guidance. Consider the approach direction, lighting, mounting space, and viewing distance when choosing the position.

Apply vinyl to a suitable clean, dry surface following the supplied application instructions. For aluminum, confirm your mounting arrangement before ordering; do not assume mounting holes or hardware are included. Do not cover controls, equipment nameplates, instructions, or other warnings.

A warning, not a protective measure

“OSHA danger header” describes the header design, not a certification of the installation or workplace. This sign communicates a warning; it does not establish a restricted zone or replace barriers, training, supervision, or safe operating procedures. The sign alone does not guarantee OSHA or ANSI compliance or accident prevention.

For the same CRANE OVERHEAD wording without an arrow, compare our text-only Danger Crane Overhead sign.
