PREZES ZARZĄDU Marek Kopras INTRODUCTION Dear Readers, This year we are celebrating our 32nd anniversary. The experience we have gained over these years has had an impact on the construction of our shoring. It is my pleasure to present our catalogue of high-quality products, manufactured according to the latest technologies in compliance with the most stringent European standards regarding construction, welding, pumping, and painting. Our line of "Shoring Systems for Temporary Wall Protection of Excavations" features structures which have been tested and have proven their reliability...

NEW TECHNOLOGIES Since the beginning of the first shoring systems, we have never ceased searching for better, more durable and cheaper solutions for securing temporary excavations. This applies in particular to individual shoring elements such as plates, rails, and struts. However, the most important factors are how the entire support system is constructed, the method of connecting individual elements and their selection, the technology of execution, the method of securing, and the order of assembly in the excavation. Each year we introduce new constructions and solutions. Materials and...

SCOPE OF CUSTOMER SUPPORT Implementation of a trench at the Volvo auto repair shop Our customers are our top priority, therefore we offer the highest possible level of support in the selection and use of shoring systems. When commencing a task, we have to choose the right shoring system in order to perform the work safely and in the most effective way possible. The owner of the Volvo auto repair shop in Warsaw, Auto Gala, requested the securing of a trench excavation in the workshop hall, which made it impossible to use traditional shoring systems. Kopras designed and produced a special...

The use of a wide range of aluminium shoring elements as shown in the drawing allows for the proper protection of smaller excavations in spite of collisions. The use of a wide range of shoring elements as shown in the drawing allows for proper protection of the excavations in spite of collisions. The use of different lengths of plates allows for a precise approach to collisions and their shoring. All elements seen in the drawings (plates, top plates, linear rails and corner rails, struts with inserts up to 10 m long, segment walls) are available in our rental. Page 10 Page 11 Page 12 Page...

ALUMINIUM STRUCTURES PIT SHORING SYSTEMS DC O X 1-0 Aluminium is a very good construction material. Its lifespan is unlimited as long as it is properly used. Special profiles made of technically pure aluminium with increased durability allow for the construction of a wide range of shoring systems. Traditional boxes of various heights of plates and segment boxes are used to avoid transverse collisions. Most aluminium elements can be mounted manually. Aluminium box plates can be mounted using corner rails, which gives a wide range of pit shoring systems. CORNER RAILS USED STRUTS ALUMINIUM...

USED STRUTS ROZPORY STOSOWANE BASE PLATES It is possible to use inserts for all struts, which enables achieving a working width of up to 2000 mm. The weight of the complete trench box depends on the used top plate and struts.It is possible to use inserts for all struts, which enables achieving a working width of up to 4000 mm. The weight of the complete trench box depends on the used top plate and strut. In the case of plates with a height of 2400 mm, a larger clearance of up to 1520 mm can be achieved. I

The use of a single sliding strut for traditional boxes provides more possibilities of use and reduces the costs associated with damage to the threads of nuts and cast iron spring holders, the so-called buffers limiting vertical deviation. Strut can be purchased separately and used in old types of boxes. 2 USED STRUTS RS 350/B strut BASE PLATES

The use of an innovative solution for fixing adjustable struts to boxes allows to avoid triggering ground resistance during assembly and disassembly. This solution significantly reduces the number of strut damage and thus reduces the cost of exploitation of the shoring system. New lower purchase cost. The specially designed sliding strut for Standardbox type M boxes allows to make pipelines with large diameters, reduces damage, and eliminates unfavourable ground resistance. The costs, however, remain at the traditional Standardbox level. A construction which can be used as a box and as a...

Segment boxes are a tried and tested solution for the city centres with a lot of lateral collisions. Our segment box is a well-proven product that has been part of our product range for years. Special sheet piles do not have defects which are typical for traditional mouldings. A drag box is a structure designed for laying pipes at smaller depths, but the possibility of dragging it behind an excavator provides significant time benefits. Thanks to the special blades and struts, the box is resistant to damage despite the use of considerable forces. Clearance height for pipes Hr [mm] Safe...

PIT SHORING FOR WATER / SEWARAGE FAILURES 1/-1 Boxes plates in innovative solutions. On this page, we present the potential of using plates/walls of segment boxes in non-standard projects. For all those who already have boxes manufactured by us and for those who are looking for the most beneficial solutions, here are a few examples of the uses of boxes in other configurations. Through the use of extensions to guide rails, we provide more space in the shoring. The use of corner connectors makes it possible to secure pit excavations, also with the use of segment walls. The development of a...
