An extremely stable design for Z-belt conveyors is achieved by using the underframe type LD 120. This type is a closed, welded base frame with supports laterally mounted to the belt conveyor and made of aluminium profiles. Depending on the requirements and application, additional lateral, crosswise and diagonal struts may further reinforce and support the underframe so that a safe standing can also be ensured with very large belt conveyors.
The underframe makes it possible to lower the flat belt down to the floor. Thus, lowest feeding heights can be achieved. Hence, belt conveyors of this design are often used as discharge transport belts from production machines. The freely overhanging flat belt area thus can also be mounted in relatively small machine pits.
The lateral supports further enable to realise a large height adjustment range. In combination with the continuous angle adjustment between 0° and 60° of the Multi-Tech angled belt conveyors it is possible to manufacture very flexible conveying technology solutions. Thus, the conveyor belt can be used as horizontal flat belt conveyor and also as steeply angled steep belt conveyor. This is of particular importance if the conveyor is to be used at many different places.
Due to the grooves integrated in the underframe supports, additional attachment parts, e.g. control cabinets, signal lamps, operator control panels etc., can be mounted easily. The grooves may also be used for cable guide and routing, if required.
