Big bag racks and modular frames

Big bag racks and modular frames are support structures from HECHT that provide the mechanical stability, modularity and ergonomics needed to correctly position and operate big bag connection systems, supports and accessories within industrial bulk processing. They are divided into three versions: table racks, compact and space-saving stand-alone units for attaching a connection system and big bag support, also for containment processes; gantry frames, self-sufficient cantilever or bridge gantries with an integrated runway rail, chain hoist and loading gear; and modular frames, flexibly deployable stations with pneumatic height adjustment and a discharge clamping device, typically operated with a forklift truck. The frames are suitable for very high spaces and ceilings with limited load-bearing capacity, optionally offer a weighing function on removal, and are made of galvanised or painted steel or stainless steel. Gantry frames are available as a space-saving cantilever gantry (floor anchoring required) or as a bridge gantry for even load distribution, while modular frames are optionally mobile or fitted with forklift attachment.

Racks can generally be categorised into three versions:

• Table racks: Tables are small and space-saving stand-alone units for attaching a connection system and a big bag support. See also support tables.
• Gantry frames: Cantilever or bridge gantries are self-sufficient stations for attaching a connection system and a big bag support. They consist of the frame and an integrated runway rail with chain hoist and loading gear.
• Modular racks: Modular racks are self-sufficient and flexible stations for the sporadic emptying of big bags in the chemical industry. They consist of a frame, a pneumatic height adjustment for big bags and the corresponding discharge clamping device for the connection system. A forklift truck is usually used as the lifting device, which suspends the big bag in the modular frame.

• Portal and modular racks:

• Independent big bag emptying station
• Also suitable for very high room heights and ceilings with low load-bearing capacity, floor conditions must be taken into account
• Removal weighing possible
• As a space-saving cantilever gantry (anchoring in the floor required) or bridge gantry for even load distribution on the floor
• Galvanised mild steel, painted or in stainless steel
• Module frames are optionally mobile or with forklift attachment, a chain hoist can also be used as a lifting device instead of a forklift
