CGW Tracker Wedge Kit
CGW Tracker Wedge Kit is a kind of most solid wedge kit in the world, which is a essential in all on-set production, for balance of crane/dolly tracker to keep stable when working.
The tradtional tracker wedge is made from wood, the advantage is cheap in cost but lots of disadvantage like easy lost, easy broken, not enough shearing force to keep the tracker stable etc.
The CGW Tracker Wedge is made from HDPE which is a very expensive material in plastic industry. HDPE is known for its high strength-to-density ratio.[4] The density of HDPE can range from 930 to 970 kg/m3.[5] The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1 (MVS2PRO density analyzer)[6]. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.[7] The difference in strength exceeds the difference in density, giving HDPE a higher specific strength.[8] It is also harder and more opaque and can withstand somewhat higher temperatures (120 °C/248 °F for short periods). High-density polyethylene, unlike polypropylene, cannot withstand normally required autoclaving conditions. The lack of branching is ensured by an appropriate choice of catalyst (e.g., Ziegler–Natta catalysts) and reaction conditions.
