M7 Longspan shelving for medium and heavy loads

An optimum storage system for manual picking according to the ‘person-to-goods’ principle Main advantages include: - Store medium to heavy unit loads. - Adjust multiple levels by 25 or 50 mm, depending on how the system is set up. - Shelves can be up to 20 m high. - Install one or more walkways to access upper shelves. - Easy to assemble. - Ultraportable. - A wide range of components adapt the shelves to your storage needs.

Basic structures Three basic structures can be built from the different components. All three have vertical frames, which come in various profiles depending on the load to be supported. Levels can be structured with: Standard dimensions: H = from 1,000 to 8,000 (in multiples of 500 mm) L = 1,000, 1,200, 1,400, 1,900, 2,300 and 2,700 mm D = 500, 600, 800, 900, 1,000, 1,100 and 1,200 mm Choosing one structure over another depends on the product to be stored, its dimensions and weight. - Beams and shelves. - Reinforced shelves. - Beams only.

Beam-shelf storage levels Each level has a minimum of two beams fitted with shelves or panels. This system is the highly suited for: - Boxes, packets or loose material. - Heavy loads in medium-sized slots. - Medium loads in large slots. - Bulky products. Beams fitted into the frames give the shelves the rigidity they need, in most cases. So, a basic rack only requires frames, beams and shelf panels. Shelf panels come in metal, chipboard or wire mesh.

Basic structures Reinforced shelf storage levels Shelves comprise heavy-duty single metal panels with reinforced edges. Reinforcement can also be fitted to enhance the shelf capacity. The shelves are held in place by four supports fitted into the frames’ side slots, which the corners of the shelf fit into. This system is ideal for: - Storing boxes, packets or loose material. - Medium-sized slots to hold light or medium loads. - Divided compartments made of vertical dividers or drawers. - Creating three-sided enclosed storage spaces. - Minimum height loss. Lengthwise rigidity is achieved by...

Beam only shelves Certain products do not require shelves for storage purposes, such as: - Hanging garments. - Hanging samples. - Tyres, wheels and rims. - Long, rigid articles. Different types of beams let you adapt the shelving to these products. The union between the beam and the uprights needs to be analysed to ensure the rigidity is sufficient, which in turn guarantees shelf stability.

Basic structures The most commonly used modular systems are those made of beams and shelves, or of reinforced shelves. The differences are shown in the next two drawings : 13 Basic components.

Units for hanging products These shelves have two solutions for hanging garments or other articles. One is made of hanger tubes and another in which shelves are combined with supports and hanger tubes. 8. Frame 9. Hanger beam 10. Hanger tube support 11. Hanger tube 12. Support 13. Z Beam 14.

Frames Composed of two uprights, they include the corresponding bracings, footplates and accessories. The front of the frames is slotted every 50 mm, and 25 mm along the side, to fit HM shelves and other accessories. Different depths enable the shelving to be adapted to the size of the product being stored. Diverse upright models, lengths and thicknesses adjust easily to a variety of loads.

Frame footplates. The frames are fixed to the floor by means of footplates, which are placed on ends of the uprights. Different footplates are available depending on the upright model. Anchor bolts can be fitted to the shelving, when required. Shims (levelling plates). Shims are used to level racks fitted on an irregular floor surface. Different plates are available for each upright and in various thicknesses to level the shelving with greater precision. Anchor bolts. Different anchor bolts are used to fix the components to the floor, depending on the strain the shelves must bear and the...

Frame unions Steel plates fixed to the uprights through the holes at their ends. Their function is to join the double shelves, giving them greater transversal stability. Wall unions Wall unions are used when single racks need to be joined to walls. Frame splice When single-piece frame uprights cannot be placed due to an installation’s height, splices are bolted inside the upright.

Beams The beams are the horizontal components where loads are deposited or where shelves are placed to store small-sized products. They are joined to the uprights by connectors or clips, which slide into the uprights’ slots. The connector’s hooks –a system developed and patented by Mecalux– fit into the main frame at both ends, which considerably increases the load capacity. Each beam includes two safety pins. Mecalux has an extensive range of beams, which covers any storage need in terms of size, load type and capacity. Safety pins These pins prevent the accidental displacement of the beams.

Two types of beams are available: Stamped beams The connectors are formed by stamping the ends of the pre-shaped profiles. This system –developed and patented by Mecalux– enables one-piece manufacturing, to avoid welded joints and, thus, provide an unbeatable load transmission. These beams are Z-shaped, with an upper vertical flange to hold and secure the shelves. The standard models include ZE-35, ZE-55 and ZE-65. Welded beams This is the classic, universal system in which profiles are welded to the connectors at the beam ends. Welding is done in cases where, due to the size or specific...
