Blogging as a place to learn to write articles, most people who know the internet technology has certainly been known blogs.
Articles in the blog is the writings of the blog owner, although there is also the result of copy-paste from other articles.
For those of you who like to write, blog is the perfect solution, where you can write whatever you want to write, good or bad your writing does not need to worry.
If you want to publish your article to all people in the world, then write your text through a personal blog and everyone will see it.
Maybe someone will give comment or criticism of your writing is meant to praise or suggestions for improvement and also an insult to you.
Do not worry, it was your writing that can not be contested
After a long time in front of my computer finally moved to write an article. Although this article was written without careful planning and with no targets. Just write and learn to type, but it just adds only blog article. Each blog entry that's just it, bored so do not get bored so it must be filled in the writings of the new, although only write articles that are less qualified, and hope to be able to write this better. Never had the desire to be a writer but not yet achieved
How big excavator you've ever seen? I'll tell you a giant excavator from LIEBHERR, Excavator R996 Litronic. This is the biggest excavators I've ever seen for real. This machine is operated in the mine where I worked. According to information from Liebherr unit was first issued in May 1995. The overall weight of this machine is 652.8 tons, with bucket capacity of as much as 34m3 bucket.
With the capacity of such machines would have a major impact on mining operations, if there is a lot of damage it will hurt the company. So maintenance should be done properly. The failure resulted in the re-do work by maintenance mechanic that is considered not necessary. The repetition of course work wasted too much time should be used for operation at a lot of money in every hour.
This is one of my job as a maintenance mechanic, I'll share it with you. How to purge and charge front suspension of 785C Catterpillar OHT.
Unit Position should be on flat and level ground and coast the machine to a gentle stop whitout using the brakes.Please prepare area or space +/-2 m from left & right side of truck.Install four wheel chock on rear tires. Turn off master battery disconnect switch, Attach a “TAGGING & LOCK OUT” tag at the battery isolation box and Attach personal danger tag.
Prepare hydraulic jack as required, Prepare for correct tools to charging and make sure the Nitrogen is used. Never used Oxygen.
Before you perform any repairs, please read all safety procedure and used MSDS system to get precaution on safe work. Connect charging chucks and hose at both front suspension. Open valves and drain oil and nitrogen charge into suitable catch-tank until cylinder have bottomed completely. Once the suspension are fully retracted wait a further 5 minutes until oil and nitrogen stops.
Check the relief valve for the grease. The relief valve may need to be removed in order to clean the old grease from the valve. Connect oil line to oil supply into the charging chuck for both front suspension. Mark zero position for reference line on the top edge of the axle and line up with zero reference at the steel rule with paint pen. Adjust the air pressure on the regulator. The air pressure must not exceed 860 kPa (125 psi). Inject oil into the suspension cylinder until the suspension rod has been extend about 25 mm from reference line (reference line on the chrome lines up with reference line on the ruler).
WARNING Release pressure in hoses before removing
Using suspension charging tool, connect nitrogen charging lines to both front cylinder. Open Nitrogen bottle valve. Adjust the regulator pressure slowly. Put the Jack under the frames and raise the truck until the rear struts are fully extended. Re-adjust the Nitrogen regulator to appropriate pressure and charge both of the suspension.
Using VIMS display to check parameter codes 720 and 722 have reached this pressure. Once both cylinder have stabilized at this pressure, close off the shut off valves and nitrogen tank. Release the pressure in the line, Remove all tool and install valve caps. Lower truck off the stands then move the truck and come to a smooth gradual stop. Check the height of the chrome rod and record the height. Specification 254 +/- 13 mm (10 +/- 0.5 inch). Measure ride height suspension after charging. If the height of chrome rod showing still below the specification , restart from step 10, but do it on one cylinder at one time, with 5 psi added on the last known pressure. Record the last pressure and ride height. Calibration the payload after adjustment the suspension.
Oil viscosity definitly as the measure of an oil thickness and ability to flow at certain temperatures. Oil viscosity is very influential on the machine performance. As a maintenance mechanic we know some oil as a lubricant, each component of the frictional machine requires lubrication to minimize wear and tear. Oil as a cooling engine components, operating machinery would generate heat, the oil can absorb excess heat directly from the engine components. When the oil is hot it wil influence to oil viscosity. High temperature oil wil reduce trhe oil viscosity, it's mean oil performance to lubricate machine component will be reduced. At some machine this problem can be overcome by using the oil cooler.

The big Off highway truck or heavy dutty dump truk by Caterpillar with nominal payload capacity 240 tons, its mean this truk can loaded until 240 tons, the capacity loaded it isn't maximum load that this truck can load. its big right? This truck ussualy operating at mining project.
I've never seen this truck at my company. By using hydraulic system for raising dump body. Caterpillar sets the standard when it comes to safetyin the design and manufacturing of , for mining industry.
As a mechanic, every job is done by using our limbs. For example when doing maintenance. In every job we often do manual handling, lifting, pushing, holding, carrying, pulling, putting and others. Many people are less aware of the dangers of manual handling is less true. Manual handling can result in incorrect direct injury or may direct us not feel right then it may be felt in the future. Manual handling of the potential that can cause injury to our body include:
·Heavy load handled
·Volume and load conditions
·Operational range
·Frequency
·Position the wrong body
·Exercise is wrong
Heavy load handled
Lifted weights, etc. are encouraged and can be a cause of injury to our bodies. At the moment did pengankatan example, the allowable weight on the lift by the average adult is 14 pounds. If the load exceeds the load is lifted then the possibility of injury.
Volume and load conditions
Volume load is handled can be the cause of accidents or injuries because it can block the view when making a treatment. Likewise, the condition of the load, it is possible to move the load resulting in a loss of control on the load. Dangerous load condition must require special handling.
Operational range
When the load will reach far or high a possibility of losing the balance of the body that can result in accidents.
Frequency
Handling of high frequency can result in loss of control in handling the load or a bad habit of taking shortcuts to shorten the time in ways that are wrong and do not consider environmental conditions that do not support.
The wrong body position
Without realizing it when making the appointment or when we do push the load with the wrong body position. Like bent back when lifting that can cause severe back injury without we realize at that moment.
Wrong exercise
The movement of what we do when making handling can cause severe injury if we do not know the ways of right.
So to avoid injuries that can occur due to errors in our manual handling required to know the ways to correct manual handling.
Here are examples of correct manual handling, I will give examples of when to move a box from the floor to the table. By the time we move the box will make the appointment, hold Baban, carrying burdens, laid back and probably will do furtherance of the load.
We need to do before the appointment is to stretch the body, it is very important to prevent muscle injury due to a strained muscle. Check road that will pass, if there are blocking the way? Please note also that we lift the burden does not exceed the capacity of our bodies. To estimate the weights we lift can be done by trying to move the load. If we will load up too much then we can make appointments or use team tools adopted.
Examination not only weigh the burden alone, should be also a survey about what things will we lift, whether it is dangerous or not?, If this thing moving?
Positions the body for the appointment of objects as close as possible to reach not too far away. Position your hands properly, well positioned diagonally, be careful of the sharp surfaces. Then position the back and legs, do not let our backs bent as you lift and use as a pedestal leg as you lift the load.
When the load had been lifted it is necessary to guard your back straight, do not change direction by turning your back. The same thing we do when melatakkan objects.
For the time being I have when I write, if there are additional, please enter your comment.
Eyes are organs which function as fital because the sense of sight. Then the eyes should be protected from foreign objects that may damage dangerous. At work, hitting hard objects, grinding and the work that could potentially entry of foreign objects into the eye should use eye protection equipment is recommended.
We have several large companies have shown their concern for eye safety when working employees. I think the small industries as well as it should be. Because of safety and health can not be considered normal. Do you want to lose sight when leaving work. How does your family think if they see you come home from work in a blind? How awful is not it? While there may be small industries that do not provide safety equipment, it would be nice if our own self is concerned about our safety.
Already many examples of accidents associated with the eye. When an employee is using a wire cup brush to clean it grind it work without wearing protective goggles, immediately separated from one wire cups with a high rotational speed wire is able to throw with great force in any direction without seeing tembaknya target. What happened kamudian? 1 / 100 seconds later, the employee yelled, a wire stuck in his eye. It was horrible.
It is very important the security of your eyes, so that a company that cares about workplace safety will give a warning if found employees do not care about their own safety. The company certainly does not want his company known for several blind employees work accident which occurred at the company.
My jobs divided by 2 based on work location, the first work location in workshop andthe second in field or mine area. To this posting I only will discuss my job i shall do at the workshop. Work roster at workshop is begun at 6 clock and end at 6 clock. It’s differ while operative workday at each location. Temporary this is just three locations I ever visit, two reside in south borneo while one again reside in east borneo. Two locations at borneo south named satui and senakin, two locations has by one company that has mine tune. While job whom i do at third location there is no different for job that done at workshop. as a maintenance mechanic My job of course do maintenance and repair to machines that is used for mine operational. Maintenance that done is maintenance service due to schedule, most often done air good filters replacement, oil and fuel. This matter is at does to prevent damage early contamination consequence exist in air oil and fuel. Dirt found on lubricant oil will have bad in engine ability within fast or slow. Besides oil replacement is done according to periodically, where does oil ability in certain age very decreased, so that necessary done replacement to innovate lubricant oil condition. For oil not yet achieve only done investigation level oil. At the (time) of do servis also done investigation in engine component, if ascertained condition from component engine broken or be estimated will broken prior to servis next so be done replacement or repair, the example condition hose that leak, so soon be done replacement to will decrease the happening of demage moment engine will operate. Decrease it operation time from engine will have to decrease it operational productivity. this is undesirable absolutely by company.

I'm graduated from a Vocational High School in Balikpapan. Balikpapan is one of city in Indonesia and a famous city as Oil city. Many Oil and Mining Company built here. ok. its enough for Balikpapan city. Now i will tell you may carreer. In the last year of my schoolarship next to graduation, some company give any presentation to uor school to reqruiting new fresh graduate to become their employee or trainee. But the Company that I got job wasn't give a presentation. it's just ads vacation on notice board. I apply for the vacation as a trainee or we called the apprentice.

OK thats my carreer, how about my job? I work as mechanic, you certain know to how a mechanic work, very tire, even less without subsidized with complete device, all be done according to manual handling (good manner manual handling ). In a flash about company where i work, company this one of company mine contractor big enough exist in indonesia. Get several contracts at different location from mine location owner . I ceritra a little shall hit my job some people consider it very heavy. Begin from office hours, I work from clock 6 morning until clock 6 afternoon, yes true 12 office hours. get up morning around 4 and prepare everything, then clock 5: 30 will wait bus that will deliver me to work place. distance from home to work place is goed during 30 minutes. At work precisely at coal-mine of course use heavy device for mine operational. for mine operational smoothness so wanted a departement that is maintenance departement heavy device that for mine operational. heavy equuipment that is rented of course need treatment and repair if (there are) any demage in device. my job is does treatment and repair in heavy device.
