The LFC Series SkidWeigh Plus System is an electronic device that can be installed on any large capacity lift truck in order to convert it into a mobile check weighing scale. When the operator activates the "W" key and the load is picked up, the hydraulic pressure on the lift truck is automatically activated and converted to a weight measurement and presented to the operator visually via an LCD display, 2 lines x 16 characters. In addition to it’s check weighing
capability, the system allows the operator to enter the Waybill
ID#, accumulate load weights under designated Waybill ID#’s, enter
tare value into the system and obtain printout tickets if the on-board
printer is connected to the monitor. Many Lift Truck Dealers have found this product to be the ideal on-board check weighing solution for the end user who has an application for larger lift truck lifting capacity equipment in their operation. For example, over 10,000 lbs. - 100,000 lbs. |
