Series HANSA of HELLING yoke magnets are convincing for their light, handy and efficient yokes. These yokes are convenient to use due to their small handle with roughened surface. They enable long, fatigue-free operation.
The series includes the UM 8, UM 9, UM 10 and UM 15 hand yokes. The UM 8, 9 and 10 hand yokes differ in dimensions (pole spacing and length), in weight and in lifting strength. Optionally the devices can be fitted with two-limbs flexible legs, whose lower limbs can be swung inwards and outwards by 45°. The pole spacing can be hereby increased or decreased by approximately 60 cm. Due to 45° inclination of the contact surface the legs fit optimal the geometry of the object under testing.
The UM 15 hand yoke is provided with three-limbs flexible legs in standard execution. Hereby the poles distance can be set in the range from 95 up to 250 mm.
All hand yokes of HANSA series meet (also with flexible legs by maximum pole spacing) the requirements of general guidelines and standards (EN ISO 9934-3, ASTM 709 and ASME- Code, Sect. V). Here a lifting strength of min. 45 N (4,5 kg) or a tangential field strength of min. 20 A/cm (EN ISO 9934-3) is required as operational capability proof.
The HANSA hand yokes are completely sealed, being fed with main voltage of 230 Volt and possess the IP 65 protection class. They can be used (with the exception of UM 8 (60 sec./30% ED) with the maximum turn-on time of 150 sec. and maximum duty cycle of 50%. The cable can be uncoupled in order to prevent breaking of the connecting bushing.
