| The Liebherr Group is a German manufacturer established in 1949 by Hans Liebherr,headquartered in Biberach an der Riss,Baden-Württemberg. The Liebherr Group’s holding company is Liebherr-International AG in Bulle,Switzerland,which is entirely owned by members of the Liebherr family. Current-generation family ownership is held by Willi and Isolde Liebherr,listed among the billionaires of 2005.Beginning with the production of affordable tower cranes,Liebherr has expanded to aircraft parts and household appliances such as fridges. The company is a major supplier of Airbus S.A.S.. Liebherr is also among the producers of the largest mining and digging tools in the world,such as loaders,excavators and extreme-size dump trucks. Over the years,the family business has grown into what is today a group of companies,employing a workforce of approximately 25,000 in more than 100 companies on all continents. Apparently in December 2004,one German site put Liebherr’s dumpers in first and sixth place as the world’s biggest,while their largest excavator got fifth position. Liebherr currently produces one of the world’s largest mining trucks,the T 282 B. They also recently introduced the new nine-axle model LTM 11200-9.1 which received the prestigious award of Development of the year 2007,for being the world’s most powerful mobile crane,complete with 100 metres (328 ft) telescopic boom. Liebherr has locations in many countries:Germany,Britain,Ireland,and the United States to name but a few. The factory in Ireland manufactures container cranes and is located in Killarney. These cranes are exported through the local port of Fenit to ports all over the world. Cranes use hydraulic oil to exploit the principle of ‘moving fluids’and ‘fluid leveraging’.
What it means is that,instead of,for example,using pure mechanical lever or screw in utilising mechanical advantage of turning big movement with less loading into a small movement with smaller loading,it rather pushes ,via hydraulic pump,bigger amount of pressurised hydraulic oil under smaller load to make smaller movement of same pressurised oil under bigger load.
Why oil? Simple,oil doesn’t cause rust,as the fluid is in metal enclosure at most of the time (except when in high-pressure hoses). To be able to use oil,it also needs to retain some sort of stable temperature and purity. Oil circulates through coolers,similar to car radiator/cooler. As oil circulates in and around moving metal parts,it is exposed to absorbing any metal shavings and other impurities. For that reason,oil also goes through a series of hydraulic oil filters,and is eventually replaced when it reaches it’s use-by date/hours. It is also changed earlier if there is any contamination discovered in hydraulic oil. How hydraulic oil reaches it’s operational pressure? It is done via Hydraulic Pump,which is again driven by crane’s own engine (usually diesel engine). All Lifting Operations are considered high-risk activities that require careful planning prior to commencement of work. Failure of lifting equipment are the second highest contributor of workplace deaths in 2006,where lifting is involved. It accounted for almost 20% of all fatal workplace injuries. The number of workplace injuries involving lifting equipment had also surged by 165% from 129 in 2005 to 342 in 2006. Accidents involving lifting equipment were the result of improper or unsafe lifting operations and procedures. This include overloading of the equipment and the use of defective or unsafe lifting gears or devices such as lifting chain,hook,rope,sling or shackle.It’s important that your employees have the appropriate material lifting equipment on hand when they need it. One should always think about hazards that may arise from work equipment,considerations when selection and purchasing new equipment,how to prevent injuries and carrying out associated assessments,and finally routine monitoring and maintenance. Work equipment includes machinery;tools or equipment used by an employee at work e.g. hammers,knives,machinery,lifting equipment,computers,photocopiers,ladders,fork-lift trucks and even your kettle! Where young people are employed it may be necessary for them to use different types of work equipment. Specific assessment should be made of the possible additional risks that may be present to that person. Any machinery that is classed as dangerous machinery such as woodworking machinery or certain types of other machinery must not be used by persons under the age of 18 unless it forms part of their training and they are under direct supervision. Professional lifting and moving equipment should be used in industries like manufacturing,rigging,machinery moving,power plants,aerospace,aviation,defense,hospitals,off shore,and more. They may consist of a full line of Jacks,Carts,Trucks,and lifting equipment including Lift Trucks,Pallet Jacks,Pallet Trucks,Hand Pallet Trucks,Electric Pallet Jacks,Hydraulic Hand Pallet Trucks,Manual Stackers,Powered Stackers,Chain Hoists,Electric Hoists,Portable Cranes,and Jib Cranes and more. Lifting products manufacturers have been fabricating custom heavy industry lifting equipment for over a decade. They develop the products with the help of engineering experts committed to listening to customers and then designing lifting devices using the newest engineering technology,including CAD,3-D modeling and FEA Programs. Personnel field experience and modern fabricating tools imply that you will be purchasing only the finest lifting equipment. Since the increased awareness of reducing workplace hazards due to high risk lifting operations there are various premiere organizations developing sound lifting products for the workplace. Low-cost material lifts are designed to enhance your productivity with highly portable solutions for a wide variety of applications. With sturdy construction and reliable performance modern day lifting equipments are an excellent value for a virtually unlimited number of indoor and outdoor uses. Plus,a wide variety of options and accessories make them extremely adaptable to fit your specific needs. So by identifying potential weaknesses and bringing those to prompt attention for immediate rectification has urged the manufacturers to design appropriate lifting equipments thereby eliminating any likely occurrence of an accident or incident. The importance of lifting equipment in ensuring industrial safety can’t be over exemplified. Installation of lifting devices is a mandatory requirement as per industrial guidelines for ensuring security of workers at workplaces. Lifting equipment are designed to ease out industrial lifting operations. The use of lifting equipment are subject to vigorous regulations as being recommended by Lifting Equipment Regulations,1998 Today,a number of lifting equipment are used to carry out industrial lifting operations,the most common ones being cranes,chain slings,pallet trucks,shacks,pulling machines and the and minimize the use of manual labor Among all the lifting devices used in factories,cranes are most popular. Cranes are of many types and vary according to their use and functionality. Most notable forms of cranes used in industrial operations are railroad cranes,telescopic cranes,tower cranes,and the like. Most traditional cranes functioned by the mechanism of lever,fulcrum and pulley. The use of tower cranes has gained popularity in high rise towers and buildings. The vertical portion of the device is braced to a concrete structure,usually located in the centre of the building and the upper part consists of two arms. The shorter arm carries counterweight of concrete blocks while the longer arm carries a lifting gear. A crane operator sits in a cabin at the top of the tower and operated the device by means of a remote control. But now days,the traditional ones have been replaced by hydraulic cranes. The basic principle behind the operation of all cranes is more or less the same. Almost all cranes function on the principle of conservation of energy. To put in simple way,the energy delivered in the load can never exceed the energy put into the cranes. Apart from cranes,shackles too are widely used lifting devices. Shackles are U-shaped devices that are used to lift piece of metal secured with a pin or bolt. Shackles are generally used in crane and other forms of rigging operations. Snap shacks are quite popular in the lot. Snap shackles function on spring mechanism. It actually uses a lock mechanism monitored by spring that can be unfastened under load. Though snap shacks are not quite safe for all industrial operations,it is a handy device that serves a lot of purpose. Among all forms of shacks used in industrial operations,pin shacks,twist shacks are quite popular. The use of bow shacks too has gained popularity. It is capable of taking load from all directions and thus reduces pressure on sides. Another important industrial lifting equipment that deserves mention if forklift truck. Though its invention dates back to early twenties,it is still one of the most widely used lifting equipment. The load capacity of the truck generally varies between one to five tons. Most common forms of forklift trucks used are hand pallet truck,towing tractor,rider stacker,walkie stacker and the like. However use of forklift trucks is susceptible to risks and should be used with adequate safety devices. In a nutshell,all lifting equipment are used to minimize use of manual labors in factories and to boost up industrial production. However,the application of the same should be handles with care and should be used only after confirming adequate safety norms. The recent crane accidents in New York City ended up causing seven deaths,damage to an East Side residential building,and now the owner may be facing foreclosure. As reported by the NY Times,“All work on the concrete hulk of what would have been a sleek 43-story tower at 303 East 51st Street ceased after the accident more than four months ago. City officials rejected the developer’s revised construction plans in June and revoked his building permit.†The buildings lender,Arbor Realty Funding announced that is was going to foreclose on the building. New York Construction accident Lawyers is being summoned to help dispute these cases. Developer James Kennelly owns the building involved in the NYC crane accident and is now faced with foreclosure. His New York Construction accident lawyer has seen a lot of action lately due to the deaths and injuries in the accident. This is because Kennelly has failed to pay $70.4 million dollars in outstanding project loans. Since this issue might take a while,the building still stands as a daily reminder of the seven deaths that occurred there. The building is still being worked on stands 18 stories tall and is located on 2nd Ave that is taped off so that no other incidents occur at the same site. Mr. Kennelly does have options however;he can refinance allowing him to repay the back loans. Due to the recent state of the economy,Kennelly might have some trouble finding a lender. Another issue is that if someone else bought the building,they would have to obtain approval from the Buildings Department to keep the project alive. People who live in the community were worried about safety when the building was being worked on. Their worries had merit because looked what happened in the end,devastation. And a community group,“the Turtle Bay Association,said the city’s Buildings Department had largely ignored its complaints about the building’s 43-story height,as well as its balconies.†People in the community knew that the construction on the building was shady in which their voices should have been heard. Since the two crane accidents occurred,Mayor Bloomberg has adjusted safety standards to be tighter and more forceful. This recent change is for the better because it will allows the citizens of New York City to have a more peace of mind. Back in February when the crane incident building was obtaining zoning and permits there was some discrepancy. Officials were afraid that Kennelly’s building was far to close to another four-story building that was connected. Another issue with the same building was that the balconies branched over other buildings as well. Never the less,the construction went on while these details were being negotiated between Kennelly and the buildings department as well as OSHA when the crane accident occurred. New York construction accident lawyers have been working around the clock to complete these negotiations as they have been going back and forth between lawyers a number of times. |
