Hydraulic Diaphragm Wall Grab H General Remarks The hydraulic diaphragm wall grab H is equipped with a permanent measuring and control system which makes it possible primarily to recognize any deviation of the vertical excavating direction immediately, and to indicate it to the control panel of the operator and secondarily to correct any deviation of the vertical position by means of a modification of the direction of the grab. Thus, high accuracy is obtained also at deeper depths (more than 50 m) and the construction of diaphragm walls by means of grab excavation is thus perfected. The hydraulic diaphragm wall grab operates free of noise and vibration. Operation is easy compared to the mechanical diaphragm wall grab. By means of the special suspension via two ropes, each of which is deflected once, the hydraulic diaphragm wall grab can be operated by means of a smaller carrier unit whereby a more economical application with improved mobility is achieved. The H XY 200 is equipped with a deviation control system for the x-axis and the y-axis, as well as with a rotation control including data read-out and monitoring system. 3

Hydraulic Tube Extracting Equipment General Remarks Tube extracting equipment 1200/350 with uncoupling device in operation Our tube extracting machines are designed for extracting tubes of 340 to 1500 mm dia. By means of an attachment, even wide flange beams and sheet piling sections can be extracted. The essential advantage of the machine is the compact construction. The complete drive including the controlled hydraulic pump is incorporated in the base of the machine which means that no obstruction by hydraulic hoses will occur on site. In order to obtain a weight as low as possible a highstrength steel is used and the complete welded construction is stress-relieved prior to machining. The special construction of the four-link gripping collar enables work to be carried out as close as 250 mm to a wall. With easily assembled collet inserts the collar diameter can be changed without any problem. The installed heating enables the use of the machine even in low temperatures. A hydraulic, fully automatic uncoupling clamp has been developed for the tube extracting machines which enables easy coupling and uncoupling of the form-work tubes. Due to the simple, clear layout of the control table, operating personnel require only a brief introduction. Leffer tube extracting machines with uncoupling device and Leffer form-works tubes have proved themselves in the toughest utilization by the leading european contractors in special deep foundation. 16

Stop End Pipes General Remarks Stop End Pipes The tube connections (bayonet fitting) are manufactured from high-strength steel and are machined after rolling. Because of higher quality material and adequately dimensioned wall thicknesses with additional stiffenings, the stop end pipes have proven to be very effective for the construction of diaphragm walls up to 60 m depth. By means of the uncoupling device which we have developed as an accessory for our tube extracting machines, the tube connections can be opened and closed fully automatically which means that the time for the installation and removal of the stop end pipes can be reduced considerably. The tube connections can easiliy be connected, they have a radial fit and are interchangeable.
