Hydraulic tools are hand-operated machines with hydraulic drives that are employed for various technological operations, such as tightening threaded joints and pressing parts in and out. They utilize a pressurized fluid—typically hydraulic oil—as the source of power to perform a job, which offers a number ofadvantagesover alternative power solutions. For example:

How Hydraulics Transformed the Agriculture Industry
A century ago, a vast majority of the US population lived and worked on farms to raise crops or cattle for personal use and profit. Initially, all agricultural operations were performed manually and required significant manpower. However, the introduction and use of modern agricultural machinery, including hydraulic devices and equipment, allowed farmworkers to complete tasks faster, reducing the number of farmhands required for day-to-day operations. This decreasing demand translated to an increasing number of people migrating from agriculture to other sectors. As it stands today, only about one percent of the US population works in agriculture.Continue reading“How Hydraulics Transformed the Agriculture Industry”

Why You Need to Be Repacking Your Hydraulic Cylinders
Repacking hydraulic cylinders should be a regular component of any organization’s annual preventative maintenance routine. The process is relatively simple and serves to keep machinery running in peak condition at all times. Most hydraulic cylinders eventually begin to leak oil from their seals. Repacking the cylinders serves to keep costs down and machinery operational. Taking the time to repackage hydraulic cylinders fixes broken links and extends the cylinders’ life span. That translates to benefits for the professionals who rely on them to complete critical work. If teams fail to assess and repackage their hydraulic cylinders regularly, they could lose out on both profitability and efficiency in the workplace.Continue reading“Why You Need to Be Repacking Your Hydraulic Cylinders”

The Most Common Hydraulic Jack Problems
Hydraulic jacks simplify the movement of large or heavy items. The jack’s hydraulic system multiplies a worker’s efforts, enabling one person to successfully lift and maneuver heavy loads with little physical strain. Jacks are also used to suspend heavy objects in midair to provide maintenance access with minimal exertion on the operator’s part. Though they’re built to be tough, hydraulic jacks can sustain damage from heavy use, improper maintenance, environmental elements, and other factors that compromise their ability to perform. Regularhydraulic jack repair和/或维护降低造成的损害these issues by identifying signs of damage early and allowing for fast correction of any problems. This is especially crucial for older jacks that have been operational for many years.Continue reading“The Most Common Hydraulic Jack Problems”

Using Directional Control Valves
Directional control valves are the workhorses heavily relied upon in the worlds of hydraulic circuits and machinery as well as pneumatic systems because of the way they allow fluids to flow into specific pathways from one or multiple sources. The most basic configuration is a spool inside a cylinder where the movement of the spool is what permits or restricts the flow of fluids through it. An actuating force must be applied to operate the valve and move it from normal (or neutral) position to working position. More complex control valves can have more than two basic positions by have multiple working positions.

For any job, in any industry, choosing the right tools to work with is crucial for ensuring smooth, efficient, and safe operations. In the automotive industry, professional and amateur mechanics alike often struggle with determining whether touse a floor jackor abottle jack for repairs. One offers stability, ease of use, and high speed, while the other provides optimal power and a compact size.

In the construction industry, safety is always a relevant issue. Although the industry has taken steps to promote a greater awareness of the importance of safety in the workplace, accidents still occur. Some of these accidents are preventable, which is why it is important to educate industry members about safe practices and procedures regularly. Just recently, in Midtown Manhattan, a woman was struck by a flying buzzsaw from a nearby construction crew.NBC New Yorkreports that the woman sustained a gash on her leg from the 3-foot blade and was taken to a nearby hospital for treatment. Thankfully, the injury was not serious. The incident is a strong reminder that accidents can and will happen, creating serious breaches in safety. In this case, the construction crew had been using the buzzsaw to tear up a roadway to fix an underground water main. Witnesses say that the blade came off the machine and was propelled down the sidewalk by its own force. As a result, workers and bystanders alike were put at harmful risk. To minimize the likelihood of accidents like the one in Manhattan, groups like the Construction Industry Safety Initiative (CISI) and Incident & Injury Free (IIF) Group strive to develop a culture where safety is a core value. Events such as Safety Week 2014, which was held in May, help promote this idea through free organized activities, employee training, and safety performance evaluations. At Metro Hydraulic, we’ve worked hard to encourage a safety culture at our distribution and service centers. We fully support efforts by the construction industry to bring the issue of safety to the forefront of discussion—and on workers’ minds. We hope that these events make a positive difference in the lives of both construction workers and the larger public.

Building Bridges with Hydraulics
This year, two major bridges in the tri-state area have either begun or planned out major renovations and infrastructure repairs. These include the heavily traveled George Washington Bridge and Pulaski Skyway. Both projects have a budget of $1 billion or more, and require substantial construction. Metro Hydraulic is proud to report that some of this work will be completed with the help of our hydraulic equipment. The George Washington Bridge, an 82-year-old bridge that connects New York and New Jersey, is set to undergo a series of renovations and upgrades over the course of seven years. According toCBS, the planned changes include replacing 592 suspender ropes, repairing the main cables, installing new safety technology, and swapping the necklace lighting our for programmable LED lights. The extensive construction project is slated to begin in 2017 and end in 2024. Like the George Washington Bridge, the Pulaski Skyway is also 82-years-old. It was recently shut down for a reconstruction project that may take about two years. The Pulaski Skyway is often used by riders who travel from New Jersey to New York through the Holland Tunnel. Unfortunately for these commuters, the bridge needs significant renovations to its reinforcing bars, concrete railings, and roadbed, among others. TheNew York Timesreports that the crossing has become “so frayed that the state installed netting to catch the falling debris.” Metro Hydraulic distributes hydraulic equipment to some of the construction companies that work on these projects and other, similar infrastructure repairs. As the tri-state area moves forward with renovations on the George Washington Bridge and Pulaski Skyway, they will rely on our high-quality equipment and timely shipments to get the job done as quickly and efficiently as possible. As a member of the New Jersey community, we look forward to the completion of these exciting renovations!
