A Power Duo for Aerated Concrete Planar Elements
Published: 28/12, 2023
With large bricks, walls grow in no time at all, but handling the hundredweight blocks is tedious and also dangerous - if you don’t have the right helpers. For the necessary work steps - moving and cutting to size - LISSMAC has two specialists in its range in the form of the LMK 220 mini crane and the MBS 760 masonry band saw, which enhance their capabilities when working together on the construction site.
The LMK 220 grabs the bulky components with its stone gripper and lifts them electrically to a height of 13 ft (4m), where the bulky load can be positioned precisely with a light hand in a working radius of 11.5 ft (3.5m).
The particular strength of the compact mini crane is the rapid moving of medium and large-sized masonry blocks - sand-lime bricks XL (KS XL) and aerated concrete panels (PPE). The stable construction at the tip of the boom can handle a payload of 441 lb (200kg) plus 44 lb (20kg) for the gripping tool. Even under maximum load, the ball bearing slewing ring enables smooth rotation and ensures a long service life.
The slimline LMK 220, which is easy to maneuver, is also useful in confined spaces and on false ceilings with low permissible load-bearing capacities. In addition to its nearly 1t dead weight, there is a 882-lb (400kg) ballast in the form of 16 swiveling weight plates with 55 lb (25kg) each. This means that rust has no chance of weakening the masonry crane, which is designed for the toughest operating conditions. For transport, the LMK 220 can be dismantled into easy-to-transport individual parts with little effort. The hand-operated hydraulic pump is particularly practical, as it helps to assemble and dismantle the tents in a short time and with little effort.
Optimal System Partner: MBS 760 Masonry Band Saw
LISSMAC’s smallest mini crane and largest masonry band saw combine to create a productivity booster for masonry work with large-format elements (PPE). On the hook of the LMK 220, the planing elements float safely and accurately onto the robust roller table of the MBS 760, which can handle cutting heights of up to 30 in (760mm) and cutting lengths of up to 27.5 in (700mm). The heavy components can be positioned extremely precisely on the smooth-running roller table for precision cutting. The 1.1 kW 400 V motor provides the power for fast cuts through the large-format stones.
The durable direct drive of the saw band impellers reduces maintenance work and operating costs. Optimally dimensioned saw band rollers guarantee a long service life of the saw band even under continuous load. Thanks to the wheel set, the MBS can be easily moved by one person. The constant and optimal saw blade tension of the saw blade tensioning force automatic ensures the best possible cutting accuracy and at the same time reduces the risk of the saw blade breaking. A quick-release lock opens the saw table with just one hand movement, which speeds up saw blade changes.
