Water-Bag Selection
Headway float bags salvage tube is enclosed and elongated cylinder shape. Its main capacity is from 500kg to 5,000kg. These are the salvage tube of choice when shallow water is a critical factor and towing is a concern.
Lifting points are equally spaced along the length of the salvage tube. Float bags salvage is the main application. The float bags also can be used as salvage tube, salvage pontoon for the supporting docks and other floating structures. And, they are also excellent for the pipe laying and other underwater construction projects. Headway elongated float bags salvage tube are manufactured using high-quality PVC coating fabric. We equip each float bags with heavy duty webbing harness, and screw pin shackles, over-pressure valves, stainless steel valves, and quick disconnects. Customized size and rigging options are available upon request.
Headway test water weight bags are designed for proof load testing the lifting equipment and structures that request proof load weight testing. When it’s newly finished, or periodic check or maintenance. Such as crane load testing, beam load test, lifeboat davit load test, derrick load testing, overhead crane load test. So, this water-filled water weight bags offer one kind of innovative crane load test weights solution. Most noteworthy, it has the advantages of Safety, Economy, Convenience, High Efficiency.
Through listening to our customers, Headway has developed the heavy-duty marine rubber airbags, which are the toughest marine salvage airbags.
Headway marine rubber airbags are the system of choice where reliable, controllable buoyancy is required. They are particularly suited for installation buoyancy on pipeline float-out, beach pulls and river crossings. Our marine rubber airbags have also been used in applications such as vessel and platform draught reduction in limited water depths. And as salvage pontoons for temporary bridges and docks. The salvors can use marine rubber airbags to salvage the shipwreck, rescue the floating bridge and dock construction.
It really comes into own when marine rubber airbags employed in heavy-duty salvage work under severe environment. Headway marine rubber airbag is enclosed cylindrical shape buoyancy units. Constructed from high tensile out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly.
Marine rubber airbags are cylindrical balloon body, with two conical head and end mouth, fitted with air tightness swivel and air inlet kits at end mouth. Polyester webbing lifting straps are around the whole marine rubber airbag body. The total lifting of these straps maintains a minimum 6:1 safety factor of its buoyancy. Can equip the auto pressure to relieve valves, which can open when inner pressure reaches rated pressure.
Headway inflatable buoyancy units are one kind of cylindrical shape fully enclosed buoyancy bags. It is known as salvage pontoon, totally enclosed air lift bags, or buoyancy bags.
Enclosed inflatable buoyancy units provide an ideal static buoyancy system for CABLE, PIPELINE, HOSE. Inflatable buoyancy bags can be attached to the pipe along the pipeline suitable for installation buoyancy on pipeline float-outs, beach pulls and river crossings. The customer can tie the inflatable buoyancy bags to the pipe horizontally. The user can control its buoyancy to allow the load to settle gently into the correct position.
Underwater lift bags are open or enclosed bottom parachute type design. These underwater air lift bags include commercial diving lift bags and professional lift bags.
Parachute type underwater lift bags are water drop shaped units. Generally, the open bottom underwater lift bags can be used at any depth for marine salvage or re-floatation objects from the seabed. Because the open bottom design makes the operation more safety. Therefore, this air lift bags is one kind of all-purpose inflatable salvage lift bag. Especially used for the scuba diving lift bags, marine salvage bags, lift bags salvage, floatation bags salvage, and float bags salvage.
The enclosed bottom parachute type lift bags have the same size as open bottom lift bags. But, there is one cover at the bottom. The user can open the cover according to the salvage project’s condition.
Gangway water bag test weights can be used for the load testing of gangway, accommodation ladder, small bridge, platform, floor and other long structures.
Our standard gangway test water bags are 650L and 1300L capacity. For the larger gangways and small bridges can be tested with our 1 tonne Mattress Bags (MB1000). We also can make other size and shape load test bags upon the clients’ special request.
Headway gangway load test water bags are made of heavy-duty PVC coating fabric material. Each gangway load testing bags equip with one filling valve, one discharge valve, and one air-relief valve. The discharge valve can be controlled by one rope. There are some handles at both sides. The worker can fix the water bag test weights by these handles.
Load cell is the necessary dynamometer instrument for the crane load test with water-filled proof load bags. Measuring capacity is available as 1t, 5t, 10t, 20t, 30t, 50t, 100t, and 200t.
Wireless crane load test dynamometer used for the weight measuring of proof load testing using water weight bags. The load cell set consist of a load link with two shackles, wireless indicator.
Our linked-type wireless load cell dynamometer is an extremely well-built instrument for industry use, as a standard wireless tool offer universal applications. Whether used as conventional crane weight or to measure force, it is microprocessor controlled for precision accuracy, calibration is easier with the wireless indicator..
Headway offer water filled proof load bags used for the low headroom bridge crane load test when the testing operation has low headroom.
Low headroom water filled proof load bags have a short height. So, it is a very flexible proof load test way where headroom is restricted. Each lifting point only can hang one low headroom water filled proof load bags. Proof load bags are the simple proof load testing method instead of traditional solid crane test weights. Water bags can be used for the proof load testing for the lifting equipment and structures. When request load test weights after it’s newly finished, or periodic check or
maintenance. For the reason that, this water-filled proof load bags offer one kind innovative water load test weight solution with the advantages of Safety, Economy, Convenience, High Efficiency.
CERTIFICATED QUALITY FOR POTABLE WATER TANKS NSF/ANSI-61 COMPLIANT
Collapsible potable water tanks are the most economical and the most simply storage way for the potable drinking water in desert, industrial, commercial, and residential areas. Headway collapsible pillow tanks for drinking water are constructed from the top grade fabric material, which is certificated comply with NSF standard. Collapsible potable water storage tanks are low profile and can be customized to meet the space requirement. These potable water storage pillow tanks can be folded easily for storage and shipment.
The potable water tanks are extremely versatile and can be unrolled and used on any area of flat ground that has been cleared of debris, they require no special tools for installation, and are easily emptied and packed for storage when not in use.
