load securementIn many cases, the importance of tying down a load on or in a truck is underestimated. It’s interesting to talk to trucking people and find out that they are very in tune with what is expected of them with regards to the vehicle they drive and the maintenance of that vehicle. But when it comes to tie downs and load securement, they usually fall short.

Securing loads in and on trucks is very important – not just to the driver, but to their customer and most importantly the general public.

Good tie downs go a long way to ensure cargo being hauled on a truck stays on the truck.

A pre-use inspection of the tie downs must be done to ensure the working load limit (WLL) of that tie down is intact. All tie downs have markings to indicate what grade they are or they will be marked with a working load limit. The higher the grade, the stronger the product – as you typically see with chain. Grade 30 is the lowest grade and is not as strong as say, grade 70 or grade 80.

During a roadside inspection by law enforcement, they will look for these markings. If they cannot find any, they will automatically rate the tie down as grade 30, the lowest option. This derating may cause him/her to take you and your vehicle out of service due to lack of adequate tie downs. Therefore, it may be helpful to conduct a pre-use inspection, per the manufacturer’s specifications, to ensure the proper type and number of chain tie downs is used.

Straps need attention too.

The condition of synthetic straps is one of the most overlooked load securement items. When straps are purchased, the manufacturer assigns a working load limit. That WLL is for straps that are intact and undamaged. This is where a pre-use inspection is needed. Straps that have damage in excess of the manufacturer’s specifications must be removed from service.

Take time to check your load securement equipment.

All too often we are in a hurry to get from one place to another. This is usually when we take chances and cut corners. This is also the time that an accident is most likely to happen. It is important to take extra time to make sure the equipment you want to use is in good condition and meets the requirements for use as a load securement device.

I sat down with subject matter expert and Magnetek controls product manager, Casey Cummins, to discuss the benefits and features of crane collision avoidance systems.

Q: What is a crane collision avoidance system?

Casey: Collision avoidance systems are electronic devices that can be installed on your crane to help prevent accidents before they happen, protecting people, the facility, the end product and the crane itself. Collision avoidance systems are typically used in overhead material handling applications where multiple cranes are employed on a single runway, as well as where a single crane is in use. They are designed to prevent crane-to-crane and crane-to-end stop collisions, increasing operator safety and reducing system maintenance.

Q: Is the demand for collision avoidance systems growing?

Casey: Collision avoidance systems are increasingly being added to material handling systems as the demand for products that improve workplace safety grows. Collision avoidance systems intervene, when necessary, to prevent accidents, and are a reliable means of preventing human error, helping to make the workplace safer and reducing maintenance costs.

Q: Are there specific standards that require this type of system?

Casey: Collision avoidance systems are designed to prevent unintentional contact between cranes or other equipment. Although there are no specific requirements in today’s general duty crane standards to provide collision avoidance, CMAA states that all collision avoidance requirements shall be specified by the owner or purchaser of the crane. End-of-travel collision avoidance should be designed to prevent unintentional contact of the crane or trolley with mechanical end stops or other equipment. Collision avoidance should reduce speed and/or stop the travel motion prior to impact.

Q: What type of collision avoidance systems does Magnetek offer?

Casey: Magnetek offers three collision avoidance systems which can be applied to all types of overhead cranes or monorails with adjustable frequency drives, soft starters or contactor controls. Multiple configurations are available so customers can choose the exact functionality, size and style to fit their application needs. All Magnetek’s collision avoidance systems are rated IP65 or better for indoor or outdoor applicationsThe collision avoidance systems are “fail-safe,” which means that if the sensor loses power, motion of the crane would be stopped and restricted.

Q: What type of sensor technology do your collision avoidance systems use?

Casey: Magnetek’s ReFlx 45 product uses a modulated visible LED light signal, while the ReFlx 120 product uses an infrared light signal. These light signals are transmitted at a reflective target and a receiver senses the reflected signal from that target. The information is then processed and the appropriate relay will open, providing for slow down or stoppage of motion. Depending on the device selected, ReFlx has a detection range between 3 and 120 feet.

Magnetek’s LaserGuard2 collision avoidance product is the most technologically advanced system available, using self-monitoring optical lasers to check a crane’s position. Its multi-distance detection feature is flexible enough to manage crane-to-crane and wall-to-crane operations. The configurable set-point range of this laser-based system (from 8 inches to 150 feet) provides the ability to monitor distances between cranes, trolleys and monorail carriers, and prevent collision between this equipment. Laser-based systems offer the most precise positioning and are particularly useful in an automated environment.

Q: What trends in the market do you see?

Casey: The industry is moving toward remote diagnostics and monitoring, which will allow crane operators to monitor the crane on their mobile phone or tablet from the ground or anywhere in the world. Magnetek offers remote diagnostics with its engineered solutions.

Is Changing a Hoist Brake Considered a Modification?

May 12, 2016






Rod, a Canadian crane services manager and recent safety webinar attendee, asked: “Is changing a hoist brake a modification? Tom Reardon, Columbus McKinnon training instructor, responds: Changing a hoist holding brake is not a modification simply because the brake is being replaced. Merriam Webster Dictionary defines modification as: “a change in something (such as a system or style).” […]

Can Spring Balancers Save Lives? Yes They Can!

May 5, 2016






Normally, spring balancers, sold by our Columbus McKinnon’s Industrial Products (CMIP) division in Wuppertal, Germany, are used to relieve operators from the weight of hand tools. By using a tapered rope drum, the weight of the attached load is compensated so that loads up to 200 kg can be moved effortlessly along a vertical axis. Standard applications would include spot-welding guns, riveting machines or multiple-nut runners. One […]
