Demag Cranes & Components
has extended its KBK light crane system to include two new components for additional safety and enhanced ease of operation.
The new components include an adjustable limitation of the slewing motion for wall-mounted slewing jib cranes to protect workers at their workplaces as well as protect material such as neighbouring machinery. Demag has also added a new cable slider to accommodate flat cables, offering a rugged design to facilitate simple installation and convenient operation.
Limited slewing motion for wall-mounted slewing jib cranes
The new slewing motion limiter for Demag wall-mounted slewing jib cranes corresponds to the slewing motion limiting function already offered for KBK pillar-mounted slewing jib cranes. Demag Cranes has modified its KBK I and KBK II wall brackets accordingly to employ this convenient safety device also for wall-mounted slewing jib cranes.
This flexible solution now allows the slewing range of wall-mounted slewing jib cranes to be adapted to the given operating requirements up to a radius of 270 degrees at any time. The pre-completed sub-assembly consists of a carrier plate, mounting bracket, perforated plate and buffer bracket with the perforated plate used in connection with buffer brackets, enabling the slewing angle to be precisely adjusted in increments of 1.5 degrees.
The new slewing motion limiter for Demag wall-mounted slewing jibs can also be fitted to the crane jibs at a later date if they are equipped with the new wall bracket.
New cable slider for reliable power supply
Offering smooth travel and ease of operation in daily use, the new cable slider is available in two sizes for the KBK I and Aluline 120 inside-running profile sections as well as for the KBK II family and Aluline 180.
Assembly is much simplified and ease of maintenance is improved at the same time with the new cable sliders. The cable can be simply inserted into the side of the cable slider during assembly, allowing the cable sag to be adjusted without much effort.
Made of wear-resistant plastic, the cable sliders can be quickly and easily introduced into the gap in the rail at any position along the profile section and removed again. Any twisting movement of the cable is prevented by a tab.
The new cable slider considerably reduces the amount of time needed for any maintenance work to be carried out. Moreover, the electric cable no longer needs to be disconnected from the supply if the cable sliders have to be replaced.
