Crane Inspection and Safe Operation Instructions

Positioning of Casters

Positioning of Casters |

A. To secure crane position while lifting load, lock diagonally opposite casters as shown.
B. To utilize maximum crane strength, lock the casters as shown.
C. To move the crane and/or load it perpendicular to the I-beam, lock casters as shown or allow casters to pivot freely.
D. To move the crane and/or load it parallel to the I-beam, lock casters as shown or allow casters to pivot freely.

Wallace Built-In Safety

Wallace Fixed-Height Visual Checkpoints |

Read, understand, and comply with the instructions on the crane and:

A. Rated load clearly stenciled on opposite sides of the I-beam.
B. Rated load clearly stenciled on hoist and trolley
C. Form 379F (this form) is attached in a convenient location by the user.
D. Caution tag attached to locking pins.

Click pins in closed position |


Make certain that all CAUTION labels are in place and legible. Replacements for damaged or missing labels are available upon request. 

Inspect that rated capacity is plainly marked on each side of the I-beam. Each hoisting unit shall have its rated load clearly marked and shall be legible from the ground or floor. 

Wallace Fixed-Heigth Visual Checkpoints

To ensure the safe operation of your crane, inspect it for bent, broken, worn, corroded, cracked, or missing parts. A series of vital checkpoints are described and shown below. Check these areas closely to ensure that all pins and fastening hardware are in place and securely attached.

Caution Tags are attached to the Locking Rings and Locking Pins in these critical areas to aid in your inspection. DO NOT USE the crane if it does not meet these and the relevant ANSI B30.17 inspection requirements.

Locking Rings on i-beam |

Locking Rings on I-Beam

Klick Pin on Main Gantry Leg |

Klik Pin

1. Brace and main legs are attached to the pin assemblies and secured with locking rings. Locking rings at each end of the I-beam should be in place and secured to ensure the I-beam hardware never slides beyond the end of the I-beam.

2. Lower main legs are attached to the caster frame casting with pins, secured with a Klik pin. Inspect casters and wheels for damage, such as cracks, bent king pins, and freedom of movement. Replace any damaged casters immediately.

General Safety Instructions for Crane Adjustments 

  • ADJUSTMENTS and/or repairs should be made in an area where they will have the least interference with ongoing operations.
  • DO NOT make adjustments when the crane is under load. If the crane is in operation, lower and disconnect the load before making any adjustments.
  • SECURE TROLLEY AND HOIST to prevent movement during adjustment of the crane.

Methods of Supporting Crane for Assembly

DO NOT ASSEMBLE, DISASSEMBLE OR MAKE ANY ADJUSTMENTS TO CRANE UNTIL the unit is supported by one of the five methods illustrated below.
