Description
Lackeby Travelling grit scraper is designed for operation in rectangular grit traps and during operation it collects both grit and grease. The scraper is adapted to embrace 1 to 3 grit chambers and has at each end a 2-wheel drive that runs along a rail, alternatively on wheels of polyurethan which are running on the tank wall. The collection of grease is done either at the inlet or at the outlet of the basin. The scraper normally runs automatically and is controlled by a timer that controls the operation time back and forth. The delivery includes sensors for scraper operation forward / reverse, which is located on one of the wagons with the driving unit and at each end position the scraper is stopped in a period of time which is adjustable by a timer. The scraper can also be operated in manual mode.
Home position of the scraper is usually at the inlet of the sand trap.
