New: Crane Systems with Wireless Power Supply and Increased Load Capacity Schmalz
The new crane section SRA 220 is the latest addition to the series of ergonomic aluminum crane systems available from Schmalz. The extruded aluminum profile version offers the highest capacity from the manufacturer and increases the maximum load from 750 kg to 950 kg. With a cross-section of 220 x 100 mm, the crane section itself weighs only 10 kg/m, yet it is extremely resilient to bending and torsion forces. The user benefits twice: first, the section makes it possible to handle loads above half the maximum weight with the unprecedented ergonomic control and freedom of movement provided by aluminum cranes from Schmalz. Second, greater suspension heights increase the range of options available when designing gantry or ceiling crane systems. The crane section SRA 220 is available in one-meter increments for crane systems up to 8 m long.
New Freedom: Conductor Line SCL
An equally recent innovation is the Schmalz Conductor Line (SCL), an alternative method of supplying power. The SCL provides electricity to all devices carried with the crane such as chain hoists and electrically operated vacuum lifters. In contrast to systems powered by a trailing cable, there is no need for a cable storage device and no interference contours caused by cable loops. For the user, less is more: the potential range of the crane can be fully exploited and at the same time it is possible to use more of the room height – a particular advantage for spaces with a low ceiling.
The SCL comprises an insulated plastic rail with a copper strip, current collector and carrier. First, the SCL is connected to the crane rail, which is a fast and simple process. After the power is connected, the continuous copper strip inside the rail conducts electricity. The mobile current collector uses carbon brushes to pick up energy at any point along the copper strip, transferring power to the consuming device (e.g. a chain hoist). In order to ensure a power supply wherever it is needed, the carrier connects the travel path of the current collector to the consuming device.
The Conductor Line SCL is supplied assembled in five different lengths, ranging from 500 mm to 4,000 mm. A rail connector can be used to string together individual elements on conductor lines of any desired length. You can use the SCL with any gantry crane, ceiling crane, or column-mounted or wall-mounted slewing crane with an aluminum crane rail from Schmalz. For gantry and ceiling cranes, installation is possible either between the crane runway and the crane girder or between the crane girder and the chain hoist.
