Cranes in the United States go through strict inspection criteria annually before they are allowed to be put into service. This ensures that all working and structural components of the crane are in proper and safe working order. According to OSHA 1926.550 “A thorough annual inspection of the hoisting machinery shall be made by a competent person, or by a government or private agency recognized by the U.S. Department of Labor.”

At Commonwealth Crane Service all of our cranes are up to date on their annual inspections, preformed by a reputable third party company. Along with annual, we require monthly as well as pre-job daily inspections to ensure all safety devices and operating aids are functioning properly. Shown above is an example of what a daily inspection checklist may look like.

Having the necessary blocking and cribbing for a mobile crane is crucial to a safe pick. More times than not with a mobile crane blocking such as crane mats, outrigger pads or wooden timber’s will be needed to get the crane within 1 % of level. Being able to get the crane level and stable can be the difference between a successful and safe day or a disaster.

Here at Commonwealth Crane Service we use kiln dried red and white oak timber’s for cribbing to give us a strong stable base for setup. Along with timbers our outrigger pads give us a larger surface to evenly distribute the weight of the crane and the load over a greater area.

Ground conditions are a crucial part in the setup of a crane. It determines many factors including where the crane is setup, the size of the crane needed, and what kind or how much blocking or cribbing materials are needed. Setting up on firm, drained, and properly graded ground is critical to the safety of the crew and equipment. Working in conjunction with proper blocking and cribbing materials the crane must be within 1 percent of level, using a properly working level indicator on the crane, with all stabilizers or outriggers fully extended and locked. The amount of extension must be the same or all outriggers and in accordance with the manufacturers load charts and procedures.

The controlling entity is responsible for the ground preparation to meet the requirements of the manufacturer’s specifications as well as the requirements laid out in OSHA 1926.1402.

Communication is key on a job site, especially when that communication is between a signal person and a crane operator. Placing materials and supplies with pinpoint accuracy is no easy task, but with an experienced signal person and operator it can seem effortless!

Signals can be given by either hand or voice. They MUST be used when the load placement is not in full view of the operator, when the equiptment is traveling and the view in the direction of travel is obstructed or when the operator and the person handling the load determines that it is necessary.

When using hand signals the standard hand signals must be used (shown above) unless when using a non-standard hand signal in which case the operator and signal person must agree upon prior to operation.

Only one person may signal the crane at a time and anyone on site is authorized to give an emergency stop signal to the operator. All signals must be given to the operator from the operators perspective.

Rigging and cranes go hand in hand with each other. Rarely will anyone be around a crane when there is not a piece of rigging within arms reach, whether that be a synthetic sling, chains, shackles, wire rope, master links etc.

Rigging being used should be inspected daily by a competent person and depending on the type of rigging being used depends on what that competent person should be looking for.

For example in wire rope slings the competent person should look for broken wires, severe abrasion, kinking, crushing, bird caging or any evidence of heat damage. While when inspecting synthetic slings the competent person should look for melting or charring, holes, tears, cuts or snags, any knots and discoloration and brittle or stiff areas along the sling.

While different types of rigging have different types of out of service requirements there is a couple that they all share, they all shall have a legible identification tag which include the name of the manufacturer, the manufacturers code or stock number, a rated load for the types of hitches used and angle upon which it’s based, type of sling, and number of legs if more than one applies.

As a construction worker, operator, oiler, rigger or bystander being in the swing radius, hazard area or fall zone when working with a crane is one of the most dangerous places you can be on a job site.

Being within the swing radius of the rotating superstructure of a crane creates numerous hazards including striking, pinching and crushing. Most of the time this area is in the operators blind spot so before entering make the operator aware of your presence. According to OSHA 1926.1424 an employee must erect and maintain control lines, warning lines, railings or similar barriers to mark the boundaries of the hazard areas. When this cannot be achieved the hazard areas must be clearly marked by a combination of warning signs and high visibility markings on the equipment that identify the hazard areas.

Wire rope is arguably one of the most important components on any type of crane. According to OSHA 1926.1413, a competent person must complete daily inspections of wire rope to identify any apparent deficiencies that may constitute a saftey hazard. Apparent deficiencies are defined in three categories.

Category 1: Significant distortion of the wire rope such as kinking, crushing, birdcaging, signs of core failure or steel core protrusion. Electric arc damage (from a course other than power lines) or heat damage. Significantly corroded, cracked, bent or worn end connections.

Category 2: Visible broken wires. In running ropes six randomly distributed broken wires in one rope lay or three broken wires in one strand in one lay. In rotation resistant ropes two randomly distributed broken wires in six rope diameters or four randomly distributed broken wires in 30 rope diameters. In pendants or standing wire ropes more than two broken wires in one rope lay located in rope beyond end connections or more than one broken wire in a rope lay at an end connection

Category 3: In rotation resistant wire rope, core protrusion or other distortion indicating core failure. Prior electrical contact with a power line. A broken stand.

Along with daily inspections,monthly as well as annual inspections are required by a qualified person and all inspection must be documented.
