Pfaff-silberblau Presents New High Performance Linear Actuators HLA

HLA series combines advantages of the proven HSE and ALSR

Kissing and Munich, 10 June 2008 – At their first participation in Automatica, Pfaff-silberblau Hebezeugfabrik GmbH, Kissing (Germany), will be presenting their new series of High Performance Linear Actuators HLA. The HLA combines the advantages of the proven High Performance Worm Gear Screw Jacks HSE and the Electromechanical Screw Rams with tubular construction ALSR of the specialist for actuator technology. Pfaff-silberblau thus fulfils the rising demands of their customers for flexibly usable and reliable drives for the most diverse applications, even under the roughest ambient conditions. In automation, the HLA is being employed in systems, which e.g. require self locking capacities, positioning and repeat accuracy. The new HLA thus has the same capable gear as the HSE series from Pfaff-silberblau, and can be used both as an individual drive (Fig. 1) as well as in multi-screw lifting systems (Fig. 2). When being used in multi-screw lifting systems, the HLA are being synchronized mechanically and e.g. when being organized with four lifting jacks size HLA 100, they are capable of smoothly lifting up to 40 tons (see Fig. 2). The linear actuators are available in two transmission stages each. They operate with lifting speeds between 0.025 m/min and 10 m/min depending on load, duty cycle and screw design. The shaft/thrust tube system optimally protects the shaft from fouling and allows for longer screw sizes while keeping its compact dimensions. In addition, the system is self-supporting, which means that the screw has a solid guide system, so that there is no need for the customer to supply some separate screw guide. Especially in the field of transportation systems in logistics, in assembly areas to lift components on working level or when feeding components in production lines, this is most important for a smooth production process. Pfaff-silberblau is offering their High Performance Linear Actuators HLA in the sizes HLA 10, HLA 25, HLA 50 and HLA 100 with a maximum tensile/compressive force of 10 kN, 25 kN, 50 kN and 100 kN respectively. A standard fitment of the HLA is a self-locking trapezoidal thread screw and an anti-turn device. Due to the high quality of the lubricant used, the High Performance Linear Actuators from Pfaff-silberblau require very little maintenance. A re-lubrication possibility is provided as standard, in line with the duty cycle and availability. The stroke lengths of the HLA are standardized; special stroke lengths are also possible in accordance with customer requirements. In addition to the standard features, Pfaff-silberblau offers their customers a series of options, with which the HLA can be optimally adjusted to customer specific requirements. For example, instead of the trapezoidal thread screw, a ball screw can be employed. Also available are various head designs, inductive or mechanical operating and safety limit switches as well as safety nuts. This will also enable the use of HLA for lifting systems that are subject to EN 1570, EN 280, EN 1756 and EN 1493. The possible applications of the new HLA series are also increased by a wide range of standardized attachments, such as swivel mounting bases, swivel plates and motor mounting flanges. It is the first time for Pfaff-silberblau Hebezeugfabrik to participate in Automatica in Munich. In Hall B1, at Stand 530, the specialist for actuator technologies not only shows their new HLA series, but also several application examples and outstanding solutions based on the HLA, the proven Electromechanical Linear Actuators (ELA) and the SHG series quick-lift gears for dynamic movement with high lifting forces, e.g. for the steel, paper, packaging or automotive industry.
