First aid training
As every year, in addition to renewing the extended* scope of periodic OHS training, all WWtech employees take part in first aid courses organized by WENA Konsulting. The course program, in addition to standards (BLS – Basic Life Support), covers the following issues: Wound management, Cardiopulmonary resuscitation (CPR), Use of an Automatic External Defibrillator (AED) Training program: Call for help – launch of the emergency medical system, the role of the witness of the event in the chain of survival Own safety, the victim, the place of the incident. Unconscious victim – dangers resulting from loss of consciousness, safe position. Cardiopulmonary resuscitistion: adult, child. Choking – first aid in choking in adults and children. Injuries and consequences of injuries – rules for providing first aid to victims of injuries. Tamping external hemorrhages and dressing suface wounds. Shock – rules of anti-shock proceedings. Immobilization of fractures and dislocations. Firest aid in case of cooling and overheating – action at high and low temperature on the human body. Thermal burns, chemical, defecation. Sudden illnesses and other healt emergencies – adenoma, myonia, seizure, stroke, bronchial asthma, allergic reaction. Poisoning – rules for providing assistance in case of poisoning. Psychological support of the victim. *Training for group leaders, foremens and works managers in: Legal regulations in the field of occupational health and safety for employers and persons managing employees, Work-related hazards and methods of protection against these hazards, Assessment of hazards occurring in the working environment.
Milling of the screw press body
As usual in such tasks, the work consists not only in obtaining the proper surfaces, but also in obtaining the appropriate tolerance of the position of two surfaces relative to each other. Therefore, the most important are the measurements carried out properly, which result not only in the current geomentry but also in the value of corrections taken into account during milling.
Nalubaale HPS, Uganda
Nalubaale Power Station, formerly known as Owen Falls Dam, is a hydroelectric power station across the White Nile near to its source at Lake Victoria in Jinja district. Its Location coordinates are: Latitude= 0.443525, Longitude= 33.1847 respectively. It is the oldest hydropower station in Uganda commissioned in 1954. It was renamed Nalubaale by H.E Excellency Yoweri Kaguta Museveni, the president of Uganda in 2001. Originally Owen falls dam was designed for ten turbines rated at 15 megawatts (20,000 hp) each (a total of 150 megawatts (200,000 hp). In the the 1990s, the station was refurbished to repair the accumulated wear from a decade of civil disorder. During the repairs, the output power of the generators was increased, bringing the Nalubaale Power Complex’s generating capacity to 180 megawatts (240,000 hp). Due to the location – distance and lack of technical and logistical facilities, apart from technical challenges, the project was a huge logistical challenge. Our scope concerned the repair of the Kaplan turbine hub at the place of the blade seat. After years of operation, the sealing surfaces were destroyed by corrosion and erosion. Therefore, the customer has decided to repair the damaged edges by installing new fragments in the form of shrinking and welded rings, which were then machined to the original, correct shape. Our scope included: machining grooves for the rings embedding in five holes – turbine blade sockets, ring embedding (these rings were also manufactured by us and delivered to Uganda), final machining after welding (welding performed by an external company), grinding of internal diameters to obtain the desired tolerance and roughness parameters.

Gas tank wagon
Repair of the flange frame after surfacing in the gas tank wagon
Regeneration of sockets for hydraulic punch cylinders
Regeneration consists in machining out the material at the point of contact with the nut in the plate on both sides of the hole for the actuator. Material losses are replaced with inserts. 4 pcs. new, turned inserts will be mounted in the grooves and screwed with screws. In future renovations, it is enough to replace the inserts.
Excavator in KWB Bełchatów
Multi-bucket excavators working in open-pit mines are one of the largest mobile devices in the world. A characteristic element is a bucket wheel, often with a diameter exceeding 20 m. And it was the bearing seat of the bucket wheel that was the subject of our concern. It is clear that the time and cost of dismantling the bucket wheel would be gigantic, which is why the only solution became mobile machining. On the surface, this is a standard work, one obstacle in this case was a spigot with a diameter of Ø630, impossible to disassemble, and located in the center of the Ø1100 socket (an element with holes around the perimeter). The size of this journal also significantly limited the working space of the machine tool. Modification of the machine tool and the use of additional fasteners were required.
Fully functional equipment is fundamental to company’s success. Every machine has precision elements, bearings and number of other parts, that enable its efficient operation. Those main elements, which ensure correct machine operation require specific solutions in case of a breakdown. Leaks, cracks and grooves are issues that have to be eliminated to ensure proper operation.
An industrial metrology
WWTECH Company provides its clients with a complex way of problems resolving, offering them three-dimensional coordinate measurements and a full 3D documentation. Due to accurate measuring devices FARO (Laser Tracker, Measuring Arm) WWTECH makes it is possible to carry out uniquely accurate, fast and non-contact measurements, results of which can be analyzed in a real time.
In all undertaken activities WWTECH gives priority to the safety. Our staff’s and the society’s health, respect for the environment are the factors which determine a whole tam activities, a place and other aspects of our work, such as transportation or cooperation with a third party.
