Below-the-hook lifts are crucial for the safe transport and movement of loads when using cranes and hoists. The goal of a below-the-hook lift is to attach a load to the crane or hoist and secure that load until it reaches its final destination. The lift serves as the connection between a hoist and its load, and must therefore be able to sustain heavy loads while maintaining a high level of stability.
A below-the-hook lift may consist of magnets, lifting beams, grapples, or vacuum lifters, and often includes secondary components such as slings, hooks, and rigging hardware. The materials and equipment used in below-the-hook lifts vary widely depending on the application. Due to their critical nature, below-the-hook lifts are highly regulated by the American Society of Mechanical Engineers (ASME), which provides guidelines for designs, inspections, and testing to ensure a standard level of quality.
An Overview of Below-the Hook-Lifting
Cranes and hoists are necessary for a wide variety of circumstances, which often requires engineers to customize the design of below-the-hook lifts to meet the needs of a given project or application. Below-the-hook lift designs are frequently adapted to account for a load’s center of gravity, shape, and size, and customization of these designs helps to guarantee safe operation of crane equipment and efficient transport of the load or loads.
In order to ensure that the below-the-hook lift is designed for optimal use, both the manufacturer and the customer participate in the engineering process for each application. This ensures design engineers and project managers consider the precise needs for the project so that they can produce a lifting solution that meets every need.
There are a wide variety of mechanical below-the-hook devices for use with cranes and hoists, including:
Spreader and lifting beams
Each design can be specifically modified with custom designed claws, hooks, tongs, and latches to ensure the most secure fit. Depending on the needs of the application, mechanical below-the-hook devices can be operated using electronic or hydraulic means.
Advantages of Below-the-Hook Lifting Devices
Below-the-hook lifting devices are the ideal option to provide the safest and most reliable load transport. Although traditional slings of wire rope, alloyed metal chains, or durable synthetic materials are easier to construct, they are not the safest way to move loads and often move or shift unexpectedly. Unpredictable load bearing puts both equipment and workers at risk, especially when transporting loads with an unusual shape, size, or weight.
Below-the-hook lifts are specifically designed to ensure optimal control of the load. Not only do they enhance the safety of the worksite, they save you time and money that would otherwise be spent finding a creative workaround with a sling or other existing equipment.
Since they are highly customizable, below-the-hook lifts are useful for even the most difficult loads. For example, if your project requires the ability to lift loads with varying centers of gravity, they can easily be managed with a custom designed below-the-hook lift with an adjustable bail. Whatever your project needs, a lifting device can be designed to move your loads more efficiently and safely.

Employees move in and out of manufacturing facilities and shipping/receiving areas many times during a normal work day. When doing so, they must coexist with a wide variety of large and dangerous equipment.
Overhead lifting systems work within a specific area to limit potential risks posed to employees and bystanders. Doing so allows lifting equipment to operate as efficiently as possible without affecting your facility’s safety levels.
Properly implemented overhead lifting systems allow product to be transported safely. Have you considered the costs related to OSHA citations, increased workers’ comp rates, potential lawsuits, medical expenses, and the temporary or permanent replacement of an injured employee? These issues cost employers billions of dollars annually. This makes investing in the safest lifting and moving systems more than just ideal—doing so is a practical, cost-saving proposition.
Inspection Requirements for Overhead Cranes and Parts
Overhead Crane Requirements
Routine inspections are required to guarantee continued safe operation of overhead cranes because of the size and weight of the objects they regularly lift and transport overhead. Whether a crane is new or altered, an initial inspection is necessary before it can be used.
Once overhead cranes are placed into service, they require two unique types of inspections:
Frequent inspections, which occur daily to monthly
Periodic inspections, which are completed 1–12 times per year
These types of inspection are intended to examine key components of the crane. This helps to determine the extent of malfunction, deterioration, or wear and tear on the crane’s components.
Items that Need Inspection and Their Frequency
The following items require daily inspection:
Functional operating mechanisms: These systems must be checked for maladjustment
Hydraulic and air system components: Valves, lines, tanks, drain pumps, and other components must be checked for deterioration or deficiency
Crane hooks: These must be checked for cracks or deformation
There are also several features that require monthly inspections or other actions:
Rope and end connections: These must be run to check for broken strands or wear every month
Hoist chains and end connections: These must be checked for distortion, twit, excessive wear, or anything else that may interfere with their proper function or cause them to stretch beyond their manufacturer’s recommendations
Written records: All records must be carefully updated with each inspection that is performed
Other inspections are performed on an as needed basis. Test functional operating mechanisms for excessive wear regularly. This may be daily or monthly depending on the amount of use your crane system gets. Rope reeving inspections should be completed as needed or recommended per the manufacturer’s instructions.
Maintenance and Design Requirements
OSHA specifies a number of design requirements pertaining to the construction of the crane’s cab and its controls. OSHA also outlines many regulations that govern the cab’s lighting, footwalks, ladders, and stairways. OSHA recommendations additionally cover the following components:
Bridge and trolley bumpers
Hoist, holding, trolley, and bridge brakes
You must implement a preventative maintenance program according to the recommendations of the crane manufacturer. If you detect any unsafe conditions or deteriorated components during your required inspections, you must complete maintenance before you can use the crane again.
Only designated personnel are allowed to perform the necessary repairs and maintenance. The requirements of 29 CFR 1910.147, the control of hazardous energy or tagout/lockout, should be used to de-energize the crane.

This problem-solving culture is reflected in every machine we make — overhead lifting systems from American Crane are designed to solve problems in workplaces of all kinds.
Hooks, hoists, magnets, and other devices affixed to overhead cranes can lift, move, and place loads for maximum facility coverage. Their range can span a narrow corridor for a dedicated task, or be designed to span an entire facility, moving any material for any process.
Simply versatile, this type of machine is similar to a crane, designed to lift and move freely suspended loads. They’re useful in manufacturing facilities as well as in construction and warehousing environments, using wire, rope, or chain to move materials.
This unique overhead lifting solution runs on tracks in either a single circuit or a route network. Installed directly into the roof of a facility, one or more carriers traverse the tracks to transport materials. They’re ideal for dangerous or hard-to-reach applications, eliminating the opportunity for human error with the fixed track system.
Each of these systems can be adapted and engineered to solve a company’s specific problems. Additionally, they do so while taking up minimal space, being installed along the edges or — in the case of monorails — on the roof of a facility. As a strong, long-lasting high-load solution, these machines offer durability and versatility in moving a wide variety of materials and containers, making workflow easy and effective.
Beyond all of these benefits, these overhead lifting systems reduce injuries and physical stress on employees. Workplace safety is the number one priority at American Crane.

October is a month full of awareness campaigns and holidays – some more widely recognized than others. We’ve become accustomed to seeing football players don bright pink shoes and gloves in support of breast cancer awareness; we look forward to seeing what crazy costumes people can come up with for Halloween; and for the perennially stressed, there’s even Moment of Frustration Day to let out all of that pent up energy (not that this is ever an issue in our office).
But here at American Crane, we feel it’s important to celebrate and promote some additional holidays that particularly matter to those of us in the industrial space. In October, for example, we celebrated Manufacturing Day on Friday, October 3rd, and we’re also pleased to celebrate Nuclear Science Week this month, which runs from October 20th to the 24th. This is a national event aiming to educate people about the field of nuclear science. Each year, one U.S. city is chosen to host the main Nuclear Science Week event, and this year it’s Seattle’s turn. Across the country, numerous events will be taking place before, during and after the actual week-long celebration. For a full schedule of events, check out the Nuclear Science Week Calendar of Events.
