Abstract:
A high productivity feed device comprising means 28, 29 for supporting objects 3 directed towards the corresponding printing machine and members 30, 35, 350 for gripping said objects, and which are coupled by way of a swinging linkage 22, 24 connected to the main printing machine drive, such that they are subjected to two reciprocating rectilinear movements in phase opposition along the object transfer direction. Downstream of said support and gripping member means there is disposed an element comprising two swinging arms on a horizontal shaft 53, on which loading means 58 and unloading means 56 for the printing machine are rotatably mounted at the respective ends. The device according to the invention is arranged to feed cylindrical objects of circular, elliptical or other cross-section to silk-screen printing machines in general.

The new Barra Tippa is a productivity device saving construction site workers loads of effort and time.

The Barra Tippa assists the emptying of conventional wheelbarrows into skip waste bins.
The use of a plank to wheel the barrow to empty its contents is known to cause serious injury.
The Barra Tippa secures the wheelbarrow minimising awkward movement under load and reduces the likelihood of accidents.

Barra Tippa Benefits:

Easy to install / uninstall in a variety of situations
Designed to improve work safety and minimise work accidents
Increased worker efficiency and productivity potential
Quality Australian engineering and components

Grove Worldwide, is a multinational corporation working under three operating businesses: Grove Crane, Grove Manlift, and National Crane.
Though initially founded to build farm wagons, Grove has grown into the world's leading manufacturer of mobile hydraulic cranes and self-propelled aerial work platforms for applications ranging from construction and transportation to mining, petrochemicals, and plant maintenance.

Grove formerly had relied entirely on a system of hand welding, temporary tools, and dedicated fixtures to perform its welding operations. Though each of these methods was adequate, the management and engineering staff knew they needed another fixturing alternative to improve product quality and increase productivity.

After a detailed study, Grove decided on the Demmeler Modular Fixturing System. The heart of this system is the three dimensional worktable designed to provide a sturdy platform for mounting the weldments with a variety of standard angles, blocks, and a wide range of other accessories. These worktables are made of heavily ribbed, high tensile strength steel, machined to very tight tolerances to ensure stability and flatness to within 0.0004ft. The 3D worktables are made in several sizes and are designed to be used alone or bolted together to accommodate larger weldments. Each worktable, as well as the major structural elements, is made with a grid pattern of 28mm mounting holes, spaced on a 100mm grid, across the face and four sides of the table. Should a closer spacing be required, subplates with a double-density grid pattern are also available. These plates offer a grid spacing of 50x50 mm and are easily mounted to the main 3D tables. This grid pattern of holes is designed to securely mount the structural elements and fixturing components to the worktable while maintaining a positional accuracy of ?0.001?? hole to hole, ?0.002?? overall. In addition to grid pattern of holes, several structural elements are also made with 28mm wide slots. These slots permit the various components to be precisely positioned exactly where they are required to suit the weldments.

Grove acquired its first Demmeler 3D table and associated components in 1995. Since then its collection of fixturing elements has grown substantially. Today the company employs eight tables, four subplates, and a wealth of other Demmeler fixturing components.
