High-end lifting unit for AGV
Columbus McKinnon Engineered Products is now supplying Pfaff-silberblau HEK10.1 lifting units as standard equipment to KUKA for integration into the KMP 1500 Mobile Platform.
The lifting unit is a special development according to DIN EN 1494:2009-05 and EN 1570-1:2011+A1:2014 Safety requirements for lifting tables specifically for this automated guided vehicle, which moves around autonomously. With a lifting capacity of 10 kN per lifting unit, large loads can be moved around very flexibly on the small, manoeuvrable platform and moved vertically at speeds of 50 mm/s over a lifting path of 200mm. Thanks to its two lifting units, the KMP 1500 transports loads weighing up to 1.5 tonnes safely through production and warehouses.
The request made by KUKA to Columbus McKinnon Engineered Products was for a highly compact design with a low installation height of only 143mm – while ensuring a 200mm stroke with a maximum clearance of +/-1.5mm in the X/Y direction. Loading with a one tonne load per unit had to be guaranteed. The maximum transverse forces of up to 3000N resulting from the acceleration of the vehicle are absorbed by the compact scissor guide system of the lifting unit.
A long service life of at least 600,000 load cycles with high duty cycles and quiet operation of less than 70 dBA were specified. These specifications were verified in endurance tests in the specially designed test bay of Columbus McKinnon Engineered Products. Inside the HEK10.1 lifting unit, which is integrated twice – front and rear – in the KMP 1500, a special newly developed Pfaff-silberblau high-performance worm gear screw jack has been installed as the core element.
The KUKA omniMove drive technology allows the KMP 1500 to move in any direction from a standing position. The sophisticated wheel technology allows for precise positioning with an accuracy of +/- 5 mm even in tight spaces. This results in space-saving and highly precise automation solutions for logistics. KMP 1500 ensures the flexible transport of loads through all process steps in production and in the warehouse, for example in the automotive industry. The mobile platform is specially designed to meet the automation requirements of Industry 4.0.
