The Wonder Lift

Gandhi Automations' retractable tail lift comes with several advantages which includes the tried and tested features of the company's well proven futura retractable range of lifts as well as various new additions.

Since 1986, Gandhi Automations Pvt Ltd has held a lead position in importing, distributing and installing entrance automation systems and warehouse equipment that are problem free and easy to operate. High speed industrial doors, sectional overhead doors, dock levellers and dock shelters, forklifts and warehouse equipment, cold storage doors, entrance automation systems and access control, etc are some of the major products of the company.
Using the tried and tested features of the company’s well proven futura retractable range of lifts; retractable tail lift has incorporated the advantage of a flat/horizontal platform which is suited for roll cage operations, especially to the typical British food industry operator. The platform is available with three way stops/leading edges, in column lift style to the three open sides, and the new fully automatic mechanically operated foot protector/roll cage stop.

Anteo superb guide rail system eliminates any "racking or bounce" of the lift frame and platform during deployment and retraction. Available in futura version, one can choose to have the facility of tilting the platform at any level, a must where the operator loads or unloads on gradients.

The guard automatically rises and falls as the tail-lift is operated. As the platform moves away from body floor level, cam locks lift the guard thus preventing anyone on the platform from trapping or crushing feet or toes, at the same time holding roll cages from preventing falling as the lift descends to ground level. As the lift is raised back to the floor level, the guard automatically falls to level with platform and body floor, allowing smooth transition of roll cages into the vehicle.

The Anteo automatic positioning in and out makes it very easy to use. The main options of the platform include fixed internal two button controls with changeover switch, wander lead with changeover switch, hinged side ramps that are 390 mm, 500 mm or 620 mm deep, safety gate, foot control and tilt cylinders.

Bent on Progress

Ashapura Volclay Ltd (AVL) sets up its first bentonite base Geotextile waterproofing membrane plant in the Bhuj district of Gujarat under technological collaboration with CETCO.

Ashapura Volclay Ltd (AVL) is an Indo-American-Japanese joint venture between Ashapura Minechem Ltd (AML) and Colloid Environ-mental Technologies Company (CETCO). This joint venture company is engaged in activities like manufacture and supply of Bentonite products to various industries in India including developing and promoting new applications for the products and also export of Bentonite products. The unique hydrophilic property of Bentonite gives it an ‘active’ quality,meaning it can swell to seal punctures within itself and also small voids and cracks that develop within concrete over the life-cycle of the building.

It has set up India's first bentonite base Geotextile waterproofing membrane plant in the Bhuj district of Gujarat under technological collaboration with Colloid Environmental Technologies Company (CETCO). Ashapura Volclay Ltd has several Bentonite based products. Some of them are as follows

Voltex and Voltex DS
Voltex is a highly effective waterproofing membrane ideal for below-grade vertical and horizontal foundation surfaces. Voltex uses the high swelling and self-healing properties of Sodium Bentonite to form a monolithic, low permeable membrane to protect the structure from water. Installation is fast and easy, requiring no primers or protection courses. Voltex is a composite comprised of two high strength Geotextile and 4.8 kg of Sodium Bentonite per sq m. Voltex DS is comprised with an integrated HDPE liner on Voltex. Typical applications include backfilled concrete walls, under structural rafts/slabs, tunnels and property line construction. Over 200 million sq m of Voltex has been successfully installed on prestigious projects worldwide.

Waterstop RX-101
Waterstop-RX 101 is a flexible strip concrete construction joint waterstop that provides a positive seal by expanding upon contact with water. Waterstop-RX101 is designed for both continuous and intermittent hydrostatic conditions and has been successfully tested to resist 70 m (231 ft) of hydrostatic pressure. Waterstop-RX 101 contains 75 per cent Sodium Bentonite content which provides superior expansion to seal cracks and fill small voids.

According to P Ramesh, CEO and Managing Director, Wirtgen India, the company has an established presence in the Indian market. In order to make its products more cost effective to the customers it has decided to start a green field manufacturing facility on 23 acre near Pune. The land purchase agreement was signed during the recent visit of Minister - President of the German state of Rheinland - Pfalz Kurt Beck to Pune. The fourth manufacturing facility of Wirtgen GmbH will have an initial investment of Rs 35 crore and is expected to begin production in the first quarter of 2010. The initial plan of the company is to produce fast moving equipment like compactors, which would have nearly 60 per cent local content in the initial period. The exact product lines are being finalised.

Marvellous MAC

MEVA Automatic Climbing (MAC) plays an important role on one of the biggest residential developments in Perth, Australia.

EVA, one of the world’s leading formwork solution supplier, is involved in the construction of The Peninsula, Burswood, one of the largest master planned communities in Western Australia on 17.1 hectare in the town of Victoria Park. MEVA climbing systems that work on the basis of hydraulic rams without any crane support are used to build the high-rise towers.

Two independent systems are running on lift and staircase shafts. MEVA Automatic Climbing (MAC) provides protection for workers with full cladding surrounding the external hanging platforms. Generous working space inside the external platforms and external trailing platforms allow the contractor to follow closely with the slab construction.

The MAC system is supported by jacking and shear key beams inside the shafts. The MAC's hydraulic system has a capacity of 20 tonne per ram and a non-return ratchet that locks on each cylinder. Thus, the climbing load is carried by concrete that has already set and offers the benefits of both safety and speed.

Inside the MAC system, an intermediary platform gives access to the 3-way adjustment devices which offer the system extreme accuracy of +/- 3 mm. It also allows the system to be quickly plumbed and speeds up the stripping and setting-up process. The top of the ram rests against the beams of the main grid.MEVA's high-performance wall formwork system Mammut 350 has been used in MAC and it offers a concrete load capacity of 100 kN/sq m. During steel fixing the external panels or shutters are retracted by hand and give access to the core structure. An intermediary working platform ensures safe fixing. MAC system also allows the usage of drop panels for confined spaces where retraction is not practical.

The top platform of the MAC is free from jacking masts and other mechanical obstacles and thus provides ample working space for concreters. Open voids are minimised on the top platform while concreting chutes ensure that concrete is not spilled inside the system. Placing booms can also be integrated into the MAC system.
