Hand Signals forCrane Operations

Hand Signals

1. ANSI B30.5 Hand Signals2. Standard Hand Signals

Who ever is in charge of any crane or hoist operations using any crane or hoist must ensure that a competent, qualified signal person is assigned to work with the crane for as long as it is working within their area of responsibility.

Mobile Crane Communications

è The code of federal regulations OSHA CFR Part 1926.550and the American National Standards Institute (ANSI B30.5) Mobile Crane, Crawler And Locomotive Crane Standards requires that a signalperson be present at all times whenever:

1. The crane is working within a boom’s length of power lines.

2. The operator cannot clearly see the load block/hook and the load at all times.

3. The crane is being backed up or moved and the operator cannot see all parts of the crane and its intended path of travel.

Standard Hand Signals

The signalperson assigned to the crane shall:

è Be positioned in full view of the operator and if using hand signals close enough for the signals to be seen clearly. The signal persons position must give him/her a full view of the load and equipment at all times without creating a hazard of being struck by the crane and/or load.

è The signalperson must be qualified with the crane and lifting operation.

è Responsible for the public and all (unauthorized personnel outside of the crane’s operating radius).

è Direct the load so that it never passes over anyone.

Signal Person Requirements

è Be in constant communication with the operator at all times with either the standard hand signals as required in accordance with ANSI B30.5 or by direct radio communication.

èHand signals should only be used when the distance between the operator and the signalperson is not great and atmospheric conditions allow for clear visibility.

Signal Person Requirements

Crane operator practices:

è The crane operator Shall Not engage in any practices that will divert attention while actually engaged in operating the crane.

è The operator Shall Not engage in the operation of the equipment when physically or mentally unfit.

è The operator Shall respond to signals given by a designated signalperson only.

è The operator Shall obey a stop/emergency stop signal at any time, no matter who gives it,

Crane Operation Procedures

Crane operator practices:

è The crane operator Shall be responsible for those operations under the operator’s direct control.

è Whenever there is any doubt as to the safety, the operator Shall have the authority to stop and refuse to handle loads until safety has been assured.

è If it is desired to give instructions to the operator, other than those provided by the established signal system, the crane operator Shall Stop all crane motions.

Crane Operation Procedures

ANSI B30.5 Standard Hand Signals:

è Standard hand signals to the operator shall be in accordance with the standards that are prescribed in ANSI B30.5-3.3.2, unless voice communication equipment (telephone, radio, or equivalent) are utilized.

è Signals shall be Discernible or audible at all times. No response shall be made unless signals are clearly understood.

ANSI B30.5 - Hand Signals

è It is strongly recommended that 2-way radios be used on all craning operations where the signaling is required. There are far too many accidents that result from misunderstood or misinterpreted hand signals and all could have been avoided by using voice communication.

è The signalperson must constantly talk to the operator at all times during loading operations. If for any reason the signalperson stops talking the operator must stop the operation.

è Adequate lighting arrangements and radio communications must be provided for all night operations.

Two-Way Radio Communication

Hand signals shall be post on the equipment or conspicuously at the jobsite.

ANSI B30.5 – Hand Signal Chart

Signalperson: Signals shall be Discernible or audible at all times. No response shall be made unless signals are clearly understood.

Hand Signals

Hoist/Raise the Load: With the forearm vertical, forefinger pointing up, move hand in small horizontal circle.

Hand Signals - Hoist

Lower: With the arm extended downward, forefinger pointing down move hand in small horizontal circle

Hand Signals - Lower

Use Main Hoist: Tap fist on top of head then use regular signals.

Hand Signals – Main Hoist

Use Whip-Line: (Auxiliary Hoist) Tap elbow with one hand, then use regular signals.

Hand Signals – Whip-line

Raise Boom: Arm extended fingers closed with thumb pointing upward.

Hand Signals – Raise Boom

Lower Boom: Arm extended fingers closed with thumb pointing downward.

Hand Signals – Lower Boom

Move Slowly: Use one hand to give any motion signal and place the other hand motionless in front of hand giving the motion signal (Hoist slowly shown as example).

Hand Signals – Move Slowly

Raise the Boom & Lower the Load: With arm extended, thumb pointing up, flex fingers in and out as long as load movement is desired.

Hand Signals – Raise Boom & Lower the Load

Lower the Boom & Raise the Load: With arm extended, thumb pointing down, flex fingers in and out as long as load movement is desired.

Hand Signals – Lower the Boom& Raise the Load

Swing: Arm extended, point with finger in direction of swing of boom.

Hand Signals - Swing

Stop: Arm extended, palm down, move arm back and forth horizontally.

Hand Signals - Stop

Emergency Stop: Both arms extended, palms down, move arms back and forth horizontally.

Hand Signals – Emergency Stop

Travel: Arm extended forward hand open and slightly raised make a pushing motion in direction of travel

Hand Signals - Travel

Dog Everything: Clasp hands in front of body.

Hand Signals Dog Everything

Travel Both Tracks: Use both fists in front of body, making a circular motion about each other, indicating direction of travel, forward or backward. (For land cranes only)

Hand Signals – Travel Both Tracks

Travel One Track: Lock the track on side indicated by raising fist. Travel opposite direction indicated by circular motion of other fist, rotated vertically in front of body. (For land cranes only)

Hand Signals – Travel One Track

Extend Boom: (Hydraulic cranes) Both fists in front of body with thumbs pointing outward.

Hand Signals – Extend Boom

Retract Boom: (Hydraulic cranes) Both fists in front of body with thumbs pointing towards each other.

Hand Signals – Retract Boom

Extend Boom – One Hand Signal: (Hydraulic cranes) One fist in front of chest with thumb tapping on chest.

Hand Signals – Extend BoomOne Hand

Retract Boom – One Hand Signal: (Hydraulic cranes) One fist in front of chest with thumb pointing outward and heel of fist tapping on chest.

Hand Signals – Retract BoomOne Hand

ANSI B30.5-3.3.3 Special Signals:è For operations not covered by ANSI B30.5-

3.3.2, or for special conditions that occur from time to time, additions to or modifications of the standard signals may be required. In all such cases, these special signals shall be agreed upon in advance by both the operator and the signalperson, andshould not be in conflict with the standard signals.
