Innovation from SCHNEIDER LEICHTBAU: RECHARGEABLE BATTERY for equipment in EX zones

The SCHNEIDER product range includes pallet jacks and weigh-lift trucks, as well as lifting and tilting devices which in many instances need to be used also in zones with potentially explosive atmospheres. It is particularly in this type of environment that rechargeable storage batteries provide an indispensable source of energy for mobile equipment and devices.
Over a long period, the company SCHNEIDER LEICHTBAU GmbH based in Freiburg has been intensively involved in researching this area, and has now launched a new rechargeable battery which can be connected to all commonly used devices and is even compatible with older models. This was one of the underlying objectives in the development of the new rechargeable battery!

Almost every manufacturer of mobile weighing and lifting equipment uses a different storage battery model, few of which are ever compatible. With its new development, SCHNEIDER has found a lasting solution to this problem.
For all companies still using a weigh lift truck from a previous generation manufactured by BRUSS, for example, the new SCHNEIDER  development is a stroke of luck: As rechargeable batteries are no longer made for this model, owners were facing the prospect that it could no longer be used for Ex zone work.

SCHNEIDER now offers a rechargeable battery which offers the BRUSS weigh lift truck a new lease of life, and is suitable not just for modern devices but also for “older generation” models.
The whole range of SCHNEIDER transportation, weighing, lifting, storage and conveying devices naturally complies with all applicable Ex protection and cleanroom-related requirements, and now includes the new SCHNEIDER RECHARGEABLE BATTERY as one of its major components.

The SCHNEIDER rechargeable battery SLB 12 with its many benefits:

• Not restricted to use with defined products
• In gas zones: For zones 1 / 2 and the highest gas and temperature category (T6)
• In dust zones: For zones 21 / 22 and the highest dust category (80°C)
• Optional voltage 12 V or 24 V
• Universally applicable with a range of different fixtures
• Low weight
• Carrying handle
• In lead gel batteries, the memory effect does not play a role!

The technical data:

• Rated voltage: DC 12 V or DC 24 V
• Lead gel batteries (Pb)
• Admissible discharge current: max 3A
• Ambient temperature -20º C to +30º C
• Weight: appr 11.8 kg

In the last sequel, we mentioned aluminium oxide (Al2O3), which is encountered in rubies and sapphires, members of the corundum family. Corundum crystals have a Moh’s hardness of 9, making them almost as hard as diamond. Aluminium oxide is also known as alumina, and in this guise takes the form of a white powder. It is used in grinding and polishing agents.

Aluminium acetate Al(CH3-COO)3 is known as acetate of alumina and has an anti-inflammatory effect. Aluminium ions act to counter the effects of microorganisms.

Potassium aluminium sulphate KAl(SO4)2 is known as alumstone and has a blood coagulation and deodorizing effect. In contact with moisture, hydrogen sulphate is formed which encourages protein flocculation and so hastens wound closure.
Alumstone (“Shaving stone/deodorant stone“) has an astringent and antiseptic effect. It is used for wet shaving as an after-shave and is also applied preceding an electric shave. Slightly moistened and guided over the skin, it binds in perspiration odour and so acts as a natural deodorant.

Aluminium oxynitride is a transparent ceramic material traded under the name Alon which is heat resistant to 1200ºC, and is harder than glass.

Aluminium organic compounds are used as isolators in semi-conductor technology and as catalysers in the manufacture of polyethylene.
