"Utility location is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication, electricity distribution, natural gas, cable television, fiber optics, traffic lights, street lights, storm drains, water mains, and wastewater pipes. In some locations, major oil and gas pipelines, national defense communication lines, mass transit, rail, and road tunnels also compete for space underground."

SCHOCK has been a successful innovator and manufacturer of ball bearing telescopic rails and linear slide systems for decades. Our products impress with their precision, high load ratings and long service life.

VVK, V.Valiuškio company has two factories in Kaunas and Siauliai. Manufactured zippers have Oeko-Tex Standard 100 certificate, which certifies that products are not dangerous to human health and the environment. Zippers are tested annually in Intertek laboratory. We produce all kinds of zippers according to customer specified length, color, and amount, as well as strings of polyester and cotton. Zippers functions: tape plus slider (T+S), closed (C/E), open (O/E), open 2 sliders (O/2S), closed 2 sliders X (Xtype), closed 2 sliders O (Otype), closed 2 sliders R (Rtype), pin / box.

Curved surface sliders use gravity as a recentering force; the operating principle is the same as the pendulum. Energy dissipation is ensured by the friction of the main sliding surface. The parameters for the bilinear constitutive bond depend on the bending radius and friction coefficient. They are divided into two types, the FIP and FIP-D series, respectively with one or 2 primary sliding surfaces that allow for horizontal displacement. In the case of very wide displacements we recommend to use double curved sliding isolators (FIP-D), which permit to reduce plan dimensions. Experimental hysteretic cycles of a FIP isolator.

These isolators are the combination of a bearing and dampers in a single device; the latter are typically hysteretic dampers of steel and/or fluid viscous dampers. As such, they are characterized by a high damping capacity. The bearing can be multidirectional or unidirectional. Isolators can also include shock transmitters or mechanical fuse restraints.
