workers to reach the top drawer as well as the bottom drawer from a comfortable position without bending over or extending their back. “We are fit for the future. Thanks to


euroTECH, we rapidly realised the project we had envisaged. It saves us valuable time and quite a lot of money, too,” adds Paul. The spiral cord running around the lifting


device serves two purposes: energy supply and control of the chain hoist. A chain guide inside the spiral cable prevents the chain and cable from becoming entangled. EuroTECH equipped the device with a


vibrating function, following a request from the customer; to separate oiled or adhesive double sheets whcih can prevent accidents caused by the uncontrolled removal of double sheets. A vacuum pump with an integrated non


return valve, vacuum reservoir and two solenoid valves generates the vacuum. The components control the suction and ventilation functions. The device is equipped with an aeration unit for fast detachment of the load. The lifting device is manufactured to DIN EN 13155 standards. To prevent operating errors and hazards, it is equipped with a range of safety and warning systems: an integrated vacuum gauge with a red/green zone, a red and green signal light, an acoustic signal and a two-handed operating handle for the ventilation system.


PALAMATIC VACUUM LIFTERS In accordance with BS EN 14238:2004 Palamatic vacuum lifters operate with a minimum surface area (of the suction foot under vacuum) of two times the cross- sectional area of the lifting tube.


A Palamatic Vacuum Lifter uses a single


power medium – vacuum, to grip and lift heavy or awkward loads. An electrical vacuum pump (or vacuum ejector pump) creates a vacuum level when a suction pad or gripping device is placed on an object load. The resulting low pressure makes the tube contract vertically and the object load is lifted. The operator controls the vacuum flow using a simple, finger touch operating valve, making the work physically easier and safer. Increasing the vacuum draws air out of the tube and the load is lifted. Reducing the vacuum allows air to enter the tube and the load is lowered. The combination of the lifting and gripping functions requires no special interlocks or devices. A quick acting non- return valve and a suction force vs. lifting


force safety factor of 2.5 times, prevent the load from being inadvertently dropped – even in the event of a mains power failure. Vacuum tube lifters are the perfect suspended-load handling aid for applications where the load is positioned below the lifting assembly’s centre of gravity. Vacuum tube lifters are not suitable for off-set or cantilevered load handling processes e.g. loading shelving/ racking - please see our Manipulator and/or PillarLift. Palamatic launched its Pal-Trac Cleanroom Monorail Hoist, at the end of last year, which has a 1000kg capacity version based on a 400v power requirement. The design is suitable for lifting during the maintenance of vessels e.g. removing Tank Agitators/Impellers, or moving BioBags /Sacks, Charge bags, Bottles for Charging and Moving Centrifuge Bowls. ●


INDEVA INSTALLS LIFTRONIC EASY AT GLASS CONTAINER FIRM


Indeva Group has installed Liftronic Easy, a rail-mounted arm that covers a working area of approximately 10 m for a glass container manufacturer who needed a space-saving system for handling heavy moulds for glass fusion. The system, mounted on the rails is designed to be compact,


allowing the whole working area to be free of obstacles for the operator, who picks up moulds from a trolley and positions them on a working table for maintenance work before putting them back on the trolley.


Picking and placing is made even simpler and more intuitive thanks to the ‘Float Mode’ function, which allows the operator to carry out the handling operation while keeping his hands on the   ergonomics, leading to increased productivity for the company.
