CM Labs announced that they have been chosen by Manitowoc Cranes to develop and deliver a series of ground-breaking simulators that showcase Manitowoc’s intuitive new Crane Control System (CCS).
COMANSA has launched to the worldwide market the 21LC1050 – a new model high-capacity tower crane designed to work in projects in which it is necessary to lift heavy loads.
Norwegian company Kolberg Caspary Lautom AS has launched a gyro-based stabilisation device called YawSTOP, which enables rotation-free and rotation-controlled lifting and loading of shipping cargo by cranes in a bid to make handling these goods in a more efficient, reliable and safe way.
The MRT234 flat top tower crane was the first to be officially unveiled in October 2017, and the feedback from end users, according to Strictly Cranes, has been overwhelmingly positive. The second new model, which is the company’s flagship crane in the new luffing range, is the LR330 with a triangular jib.
“One really strong aspect is that only two people are needed to completely assemble the MRT234’s jib over a period of a few short hours. This crane boasts nine different jib lengths, ranging from 70m to 28m,” said Eng. Domenico Ciano, technical director at Raimondi Cranes. Read more
The investigation analysed 249 industrial overhead crane incidents that occurred over the past 10 years.
According to the study, a total of 838 Occupational Safety and Healthy Administration (OSHA) violations were committed across the 249 incidents, which caused 133 injuries and 133 fatalities.
The study found that the most common reason for overhead crane incidents were failing loads, which can happen if the load is unstable or poorly rigged. Read more
According to the Crane Inspection and Certification Bureau (CICB), approximately 80 crane-related deaths occur every year. Of all crane-related incidents 90% are due to human error, 50% results in a fatality, and 40% involve someone being struck by the crane or an object that the crane is lifting or moving.
A solution for modernising cranes is developed by PaR Systems and called EXPERTOPERATOR, which was designed to help operators by reducing load sway by 95%. PaR is a global manufacturer of advanced automation, robotic and specialty material handling solution. Read more
In summary we have more cranes than ever before, situated in our most densely populated areas. Never has there been a more important time to focus on what we can do as an industry to maintain a high level of safety.
Last week, there was an incident in Melbourne where a luffing tower crane was damaged during high wind, leaving the boom in an unstable and unsecured position posing a risk to a large number of residences and businesses below (see photo).
There were evacuations and business shutdowns for over 24 hours, but fortunately no injuries or loss of life. It’s important that while WorkSafe conduct their investigation, we as an industry focus on the facts and lessons learned so we can improve on our safety standards and reduce the risk of this or similar incidents happening again. Hence this bulletin is not here to focus on liability and fault, but rather prevention. This graphic explains the effect of high windspeed and the mechanisms that exist in cranes to deal with high windspeed.
For the boom to be blown backwards, the crane needed to be in a position with either the boom too high and/or the machinery deck unable to slew (weathervane).
Worksafe will investigate whether:
1. The crane was improperly parked for out-of-service.
2. The crane was properly parked but malfunctioned.
3. The crane was properly parked but there is an inherent design flaw with the particular model of crane.
As an industry collective, we must be two steps ahead of all three scenarios above.
This starts firstly with conducting an assessment on the crane installation and the crane itself, to ensure its condition and working order. CraneSafe is one programme widely used and NATA-endorsed.
Secondly, operators and riggers need to be adequately licenced, trained and verified to operate the specific machine. This is an ongoing challenge with the current high demand for labour.
Thirdly, faults or issues detected on crane need to be documented and rectified immediately to ensure all aspects of the crane’s function are working 100%.
The owner’s manual is gospel when operating any crane. It needs to be accessible to the operator at all times and should include instructions such as positioning of cranes while out-of-service. If such instructions are not readily available, they should be obtained, or further engineering advice sought.
Correct permits and approvals are required for setting up cranes that slew over private property adjacent to worksites. Sometimes to leave the boom in the correct position stipulated by the manufacturer may conflict with the approved operating area. If this occurs, then manufacturer guidelines should not be deviated from; and further clarification with asset owner/principal contractor should be sought. Point 3 is rare but not impossible.
Generally, manufacturers conduct rigorous validation programmes that factor in all operating conditions. So, if a crane does not perform or respond in the intended way, the operator needs to highlight this and escalate the issue immediately.
With no fatalities or injuries from the incident last week, as an industry, we were fortunate. So, let’s all learn from the incident and pull together and do what we can to ensure we have a safe crane industry today, and in years to come.

Palfinger’s assistance systems integrate mechanical extensions into the overload protection system and weigh loads directly on the crane to further increase efficiency, and can easily be activated by the crane operator via the radio remote control PALcom P7.
The systems can be used on three of Palfinger’s heavy-duty loader cranes (PK 135.002 TEC 7, PK 165.002 TEC 7, and PK 200002 L SH) and on all of its TEC 7 loader crane models. Read more
He ran Verticon for two years prior to starting Reds Global. Persistence and innovation has seen this business continue to grow. Having its main depot in Sydney, it now has cranes working in key markets around Australia although the Greater Sydney area has the highest concentration.
Things have changed a lot in tower cranes in Redman’s time in the industry. At the start, Favco diesel hydraulic tower cranes dominated the market and the average age of the cranes was much greater in the earlier era (the average age of the Reds Global fleet is three years). Read more
Aptly named EcoLifts, the range features a patented stored-power lift/lower system and requires no batteries, on-site power, or hydraulics.
This game-changing feature means EcoLifts deliver trouble-free, clean, green operation with no need for hydraulic oil and no leak points. They have low maintenance requirements, run at a low total operating cost and offer the potential for 24/7 use. Read more
