Hand Crank Winch Used to pull various pieces of equipment in the main line sewer, such as sleeve installers, carriers, lateral launcher, deflection gauges, kit of inflatable plugs for segmental testing, etc. Easy to move by flipping the winch on its wheel and using the legs as handles. Setup allows two different speeds. The winch is provided with 500 feet of 3/16" galvanized steel cable. Easily dismantled for convenient storage
Segmental Sewer Air Test Kits Segmental testing is used to identify and pinpoint leaking joints in sewer collection systems. The inflatable plugs are winched in tandem down the line and positioned to straddle the joint or span to be tested. Once the plugs are inflated, a low-pressure air test is performed to verify the integrity of the joint or span and to localize sewer defects. Lateral connections and lines can also be tested when there is an above ground access for the introduction of an inflatable sewer plug from the cleanout. The mainline plugs are positioned on each side of the lateral connection and the push plug is inserted into the cleanout access isolating the lateral connection and lateral line. Flexible Push-Type Test Rigs are used to perform low pressure air tests on laterals from an above ground access. Contact us with your application and requirements.
Flexible Push-Type Test Rig for Segmental Pipe Testing Logiball Push-Type Test Rig is used for segmental air testing of lateral lines, from the cleanout or above ground access. The standard test chamber between the two inflatable bladders is 5 feet long. A 3/4 semi-rigid hose is used as a push rod and to inflate both bladders in one operation. Air for the test chamber is supplied thru a 1/2 semi-rigid hose to be used as a second push rod and lateral test line. Logiball Flexible Push-Type Test Rig can be used in lines 4 to 6 inch in diameter. For sealing defective laterals using chemical grout, use the Flexible Push/Pull Type Packers The control system for inflation & test is offered separately.
Design allows to seal laterals connected to manholes. Injections have been done up to 30 feet. Logiball Man Entry Pipe Lateral Grouter is an inflatable bladder with threaded adapter used to install our standard lateral grouting plugs to seal laterals from a man entry pipe or a manhole. It includes one inflation port for the lateral bladder, one inflation port for the 4-6 bladder, two ports for the chemical grout and one void liquid filled pressure sensor line.
