In addition to its extensive line of high-pressure hydraulic cylinders, Enerpac is also widely known for its extensive collection of high-quality, high-pressure jacking systems. These systems are designed to be portable and suitable for tight spaces. These Enerpac high-pressure jacking systems operate as part of integrated lifting mechanisms, working to grab and lift or lower strands and cables placed through the hollow centers of the equipment.
What is the Enerpac Strand Jacking System?
High-pressure jacking systems like those offered by Enerpac have a range of industrial uses, including lifting, positioning and moving large and heavy structures and equipment. The Strand Jacking system offered by Enerpac offers high levels of innovation and efficiency. Based on the concrete post-tensioning principle, the technique used by this system has made significant changes to the ways that industries can move and reposition heavy objects.
The full Enerpac Strand Jacking system bundles a group of steel strands or cables. These are then placed through a hydraulic cylinder. Located both on the top and the bottom of the cylinder are anchoring systems; these systems use wedge-shaped grips to fix the bundle of steel cords in place. Moving the cylinder in and out with the grips engaged succeeds in lifting or lowering the burden attached to the steel cables and strands.
How Does an Enerpac Jacking System Help?
Enerpac designs its technology with a focus on safety, and all of its products are fully tested and certified for safety. Every installation comes with a complete English-language operation and instruction manual. These strand jack systems offer high capacity and are available with options that range from a 30-ton capacity to a 1,000-ton capacity. The number of strands used in each Enerpac jacking system determines the amount of weight that it can safely bear.
These heavy lifting solutions from Enerpac are also designed for ease of use. This equipment helps industrial operations to increase productivity and ease of operation. By using the most advanced technologies to generate force, Enerpac helps to maximize the ability and use of this equipment.
Enerpac also offers a range of maintenance and repair services to clients. Its worldwide group of distributors and service centers offer high-quality service for all Enerpac products and lifting systems.
What Are the Industrial Uses of Enerpac Strand Jacking?
Enerpac’s strand jacking technology has helped to accomplish exceptional building projects with a higher level of speed and safety than would be otherwise possible. Thousands of industrial projects around the world have been made possible due to this innovative system for lifting, moving and positioning heavy objects and large loads. Some of these successful projects include:
- London Eye – The world-renowned London Eye in the United Kingdom was lifted into place using Enerpac’s HSL-series strand jacks. This famous observation wheel that looks over the British capital is the tallest in the world, with a height of 135 meters.
- Abu Dhabi Airport – At the Abu Dhabi airport hangar, steel roof segments weighing 2,000 tons each were lifted into place using Enerpac HSL-series strand jacks. These three steel roof segments were constructed on the ground and lifted into the air to create large aircraft maintenance hangars suitable for working on the latest Airbus A30 planes.
- Golden Horn Metro Bridge – This landmark cable bridge connects the Beyoglu and Fatih districts on the European side of Istanbul, Turkey. In order to construct the bridge, deck segments weighing 300 tons were lifted 17 meters high from a river barge and installed into place using Enerpac jacking systems.
Boating! Like most enthusiasts, this is the most exciting part of Spring. However, if you’re too quick to get out on the water, overlooking the safety of your craft can cause preventable challenges this year. Let’s make sure to have fun and be safe all season. With a just a bit of due diligence before hitting the water, you can make sure that all the components of your craft are in top shape, ready for a safe season of fun on the water.
If you’re an owner of a gasoline-powered boat, Racor suggests a full seasonal inspection of your fuel system. When gasoline is not blended correctly, the whole system is negatively affected. This is especially true when inspecting the plastics in your marine spin-on filter fuel bowls. After checking all components for leakage and seepage—such as hoses, fittings, filters, etc.—make sure to repair any problem areas immediately.
Fuel System Maintenance Item #1: Plastic Bowls
One of the most critical components to check along your marine fuel system is the plastic collection bowls on the gasoline filter. These clear bowls will show signs of wear and tear for various reasons, and they must be attended to regularly. Changes in the formulations of gasoline (such as concentrations of ethanol over 10%), the age of the bowl, running with high temperatures, UV Light, and some fuel additives can damage clear plastic filter bowls. Look out for clarity loss, crazing, and bowl shrinkage as signs of a unit requiring maintenance.
Part of the routine inspection of your clear plastic bowl is checking for water, deformation, discolorization, and haze. Plastic filter bowls are designed to last many years, however, if you notice excessive signs of wear or breakdown, immediate replacement is required.
Fuel System Maintenance Item #2: Daily Fuel Filter Inspection
A daily inspection of the collection bowl for water or other contaminants is required. If you have a see-through bowl installed, then this process is even more straightforward. A note of caution: water and gas can look very similar, so make sure not to allow the bowl to fill with water before draining. If you have a metal bowl unit installed, you will need to do things a bit differently. Drain off about a half a cup and inspect for large droplets of clear water at the bottom of the cup. If you see that more than half of your sample is water, drain off more fluid until no more water is evident.
Fuel System Maintenance Item #3: The Filter Element (Check it often and carry spares just in case)
As per guidelines, fuel filter replacement should occur every six months. If you are experiencing power loss, replace the fuel filter immediately. Also, if you notice sediment in the contaminant bowl, or if you can see visible rust, it is wise to replace the filter element as soon as possible. Keep in mind that just one tankful of gunky fuel can clog a new filter faster than you can get across the lake and back.
Pro Tip: Write the date you changed the filter on the unit for your reference.
Hand tighten your contaminant bowl to the filter element; about a half turn after hitting the gasket. The same technique applies for the filter element to the head as well. Never use a strap wrench or other device to tighten the unit in place.
Note of Caution: Only install Racor see-through contaminant bowls on outboard applications where the filter is in the open air. Use Racor metal bowl gasoline filters on vessels with enclosed engine spaces. Also, adequate ventilation is a must; before starting a gasoline-powered inboard craft, run the Engine Blower for at least five minutes.
Choosing a vacuum pump for your application depends on your desired vacuum level:
Gast Vacuum/Pressure Diaphragm Pump with Vacuum Gauge, Dual Series Head
Ultimate vacuums down to 0.3 mbar (0.2 Torr):
- Diaphragm Vacuum Pumps
- Piston Vacuum Pumps
- Venturi Vacuum Pumps
- Ultimate vacuums down to 2 x 10-3 mbar (1.5 x 10-3 Torr):
- Rotary Vane Vacuum Pumps
- Ultimate vacuums down to 1 x 10-8 mbar (7.5 x 10-9 Torr):
- Turbomolecular Vacuum Pumps
Also consider the following characteristics, which may influence which vacuum pump you choose:
- Chemical compatibility. Determine the compatibility of the gases used with the pump and any potential issues with the process gas (such as moisture)
- Pumping speed (volume flow) and pressure requirements. Assess the vacuum pump’s capability to produce both the required pumping speed (volume flow) and throughput (mass flow) against the process’s needs by using the equation Q (gas load) = S (pumping speed) x P (pressure) calculation
- Pump Installation. Include port connections and requirements for ancillary equipment, such as a roughing pump, in your selection
- Pump Maintenance. This covers frequency of maintenance cycles and the necessary level of expertise to carry out the service
- Costs. Consider not only the initial purchase price of the vacuum pump but also the operating costs, maintenance cycles, and associated costs
