VIBRATOR

Suitable For Finishing Suspended Floors

A TOTALLY enclosed vibrator for compacting and finishing suspended concrete/hollow block floors is being produced by E.P. Allam and Co.. Ltd.. Arterial Road, Eastwood. Leigh- on-Sea, Essex, UK.

Mounted in a framework with brackets to fit on to two screed boards and driven by a Villiers Mk. 15/2 HS air-cooled engine, the Duo Screed, as it is called, can also be used for compacting ordinary concrete floor areas, paths and roadways.

Greater compaction is claimed to be achieved at a single pass as a result of using two screed boards. The vibrator can be positioned anywhere between the brackets, concentrating

the vibration on the leading or trail- ing beam if necessary.

Adjustable side rails can be set to ensure the floor slab is level in both planes. The unit can be guided by one man in the centre or by ropes from either side and operates between the side rails.

Agents include: Landis Bros. & Co., Ltd., Hong Kong, and Ua Withya Phanit Co. Ltd.. Bangkok. The mak- ers are seeking agents in other S.E. Asia countries.

MECHANICAL GRAB Operates from Fork Lift Truck or Crane

GRAB for stacking or unloading blocks and kerbs will lift ten 3ft. kerb stones weighing some 14 cwts. without the use of hydraulics.

Millars' mechanical grab

The grab is simply attached to the forks of a lift truck and bolted in

position. The lifting arms are placed

over the batch of kerb stones to be lifted and the lifting device is then released by cable from the driving position. The arms then apply pres- sure on the ends of the blocks which are ready for lifting.

This lifting mechanism is patented and ensures that the pressure between

the jaws is derived from the weight of the grab and the load acting through and multiplied by the crank lever. When the load is put down the locking device immediately and auto- matically acts to release the blocks and the grab can be lifted clear.

The jaws of the grab are fitted with resilient rubber bonded grips to allow for slight variation in lengths of the components of the load. The grab can off-load into stacks of 10 which can then be moved into posi- tion on site as required.

Millars' Machinery Co., Ltd.. Bishop's Stortford. Herts.. UK, are the makers. Agents are: Jardine Waugh (Malaya) Ltd., Kuala Lum- pur: Jardine Engineering Corp., Ltd.. Hong Kong: Equipment Marketing Corp., Manila; and Jardine Waugh and Co., Ltd., Bangkok.

WELDING SET Designed for Light Jobs on Construction Sites

OF compact, one-piece design, the Armourweld DA 122 DC welding set has a performance suitable for the lighter welding jobs on construction sites.

A strong wrap-around steel skirt and a streamlined canopy protect the whole machine. There is a central lifting point and an undercarriage with rubber cushioned castoring wheels to make on-site handling easier.

Welding Industries Ltd., Black- swarth Road, Bristol 5, UK, are the makers. They are seeking agents in S.E. Asia.

CONCRETE PLANT

Can be Set Up for Automatic Production

A FEATURE of the new Arbau Por- tabil series of concrete mixing plants large aggregate quantities can be stor- is the high feed chute behind which

The aggregate weigh batcher is de- signed as a mixer skip. Once the weighbatching operation has been completed the weighbatcher, which is suspended in an

an elevator carriage. rises above the mixer feed opening for discharge. During all stages of travel the weighing functions of the aggre- gate weigh batcher are maintained to permit filling and discharge control at any time.

The sequence of the different opera- tions has been so timed that at the completion of a mixing cycle the ag-
