The LS400 is the same line as the LS200 system with the difference being the LS400 possesses a four-wheel cart that provides a traction system with greater towing capacity and is compatible with hoses of a maximum diameter of 160 millimeter with as much as 150 meters in length. Like the LS200, the LS400 has an articulating elbow of six inches in diameter, although its use limits the system’s traction while it is acting with leverage in the lateral part of the cart.
