RUD Chains manufactures a range of conveyor and drive systems for the bulk materials industry. The company’s trough chain conveyors — also known as drag chain conveyors — are designed for the dust-free, horizontal and slight-inclined transportation of bulk materials. 

According to the company, the conveyors combine a high wear and heat resistance with the option of multiple inlets and outlets.

Trough chain conveyor systems have been used to convey goods that are ideally suited to transporting powdery, grainy, flaky, dusty or fragmentary material. Examples of transported materials include cement, ash, wood chips/shavings, food, animal feed, recycled municipal waste fertiliser, gypsum and coke.

The trough chain conveyor has been used across a range of market segments from construction, chemical, agriculture and recycling to mills, port cargo handling, food and feed.

Key features and benefits

  • The trough chain conveyor system comprises a drive station that consists of flange or pedestal bearings, dependent on the size. Sealing is provided by grease-filled, double-radial shaft seals. For maintenance, the drive station and inspection door can be dismounted. The drive consists of a standard geared motor unit; safety clutches can be provided to prevent overloads.
  • The trough consists of individual, standard-length sections with connecting flanges. Hold-down rails are recommended for most of the materials to be conveyed. These prevent the material from building up and thus the chain climbing.
  • The take-up station has flange bearings to hold the take-up shaft. The shaft exit points in the housing are equipped with grease-filled, double-radial shaft seals. The chain take-up is generated and set by spring-loaded pressure screws.
  • The conveyor chains used for this system are forged, fork-sprocket chains that have been heat treated or case hardened. The resistance to wear can be further increased by hard surface welding. Forged link chains offer many advantages: they are robust and offer a high level of operational safety, while allowing for horizontal, inclined and vertical conveying.

RUD manufactures a range of lifting and lashing applications that guarantee ultimate safety when lifting and moving heavy loads. Offering over 500 different tested and certified lifting/lashing points for bolting and welding which cover a working load capacity range from 0.6 to 200 tonne.

They offer standard and bespoke applications to meet even the most demanding project aims and working environments. Their innovative WBPG 85-200 tonne hoist ring, is used for heavy engineering, lifting, across the offshore, construction industry and many more.

RUD are a well know manufacturer and supplier for a range of hoist chains used across industries such as offshore to the entertainment industry. RUD hoist chain can be supplied from the smallest size – 3 x 9 mm up to the world’s largest – 32 x 90 mm.

Innovation and product development plays a huge role across the RUD Group. RUD were one of the first manufacturers approved for grade 120 chain, known as ICE 120. RUD ICE 120 chain offers many advantages; offering a high resistance to crack corrosion according to to PAS 1061. The ICE chain offers a reduction of weight of more than 25% than the larger Grade 80 chain, making it easier to handle, environmentally and health and safety friendly.

RUD offers a range of RFID Radio Frequency Identification Technology, being one of the first manufacturers to offer the RFID chips embedded into our applications, helping to ensure an ultimate safety factor in monitoring and managing safe working product effectively.

Materials handling plays an important role across a range of RUD products, one of their latest products the Tool-Mover is becoming increasingly popular across plant and injection moulding environments. It offers ultimate safety to your operator, helps reduce costs to potentially damaged tools when handling and safely handles weights from 6.3 – 32 tonnes.

The RUD product portfolio is impressive; from conveyor and drive technology for bulk material handling, energy to the maritime industry. They also offer a wide range of Tyre protection chains for quarrying; as well as snow and automatic chains for commercial and emergency vehicles. The RUD Group also supply lifting and lashing chains, as well as non-skid traction chains to the MOD.

RUD offer standard and bespoke solutions to meet a wide range of project aims and working environments.
