HEAVY ENGINEERING AND WEAR PARTS delivering outstanding fugitive material control.”
An external liner can be installed and adjusted more quickly and easily, without the need for a grinder or torch, using special mounting tabs, according to Marshall. Clips for bolting the liner are initially welded in place and do not need to be removed when the liner wears out.“ Since the work is done from the outside, without any grinding sparks or torch flame, the hazard of explosive dust from tool usage is greatly reduced.”
Replacement liners come in a standard length of 1,829 mm, and Martin Engineering uses laser cutting technology to create the complex geometries necessary for a custom fit, according to Marshall.
He adds:“ The new liner is easily retrofitted onto existing equipment. Installers simply cut back the chute wall on existing chute boxes to accommodate the external wear liner. On new installations, the chute is easily engineered to work with the new liner design, as well as other Martin Engineering components such as dust curtains, trackmounted idlers and cradles.”
The T-Slot mounting configuration allows faster and safer maintenance without confined space entry
T-slot mounting interface allows the liner to be adjusted from outside the chute wall, eliminating the need for confined space entry.
The strip and its bottom edges should be machine-cut to the trough angle and the length of the transfer point to help seal the enclosure, Marshall says. The angle helps the unit better protect the skirting from larger material and spillage, allowing the skirting to focus on sealing in turbulent, dusty air. This prolongs the life of the skirting, reducing maintenance and downtime, according to the company.
“ Not all transfer chutes can accommodate a urethane skirtboard liner, so a metal liner is required,” Marshall explains.“ Wear liners are typically ¼-inch( 6.35 mm) sheets of metal welded to the inside of the chute, with the skirt seal mounted on the outside.” Instead, Martin Engineering designers came up with the idea of raising the chute work about 100 mm above the belt, out of the way of the material, then putting the wear liner on the outside.“ Using this approach, the material still hits the liner without damaging the chute,” Marshall says, with this configuration allowing for service outside of the enclosure
After elevating the chute box above the material flow, a 9.5-12.7 mm thick abrasionresistant liner plate( AR500) is mounted on the outside of the chute, followed by the skirt seal. Mounting brackets with jackscrews provide a tight hold, with precision adjustment of the wear liner to reduce spillage.
“ This system closes the gap between the liner and the sealer, thus eliminating abrasion from trapped material without interfering with existing supports,” Marshall says.“ When accompanied by skirting and clamps, the system forms a tight belt seal,
Addressing a missing link
Load and haul attachment manufacturer, Schlam, is further developing its global operating model by extending its product range and leadership team, it says.
New products include a broader range of buckets, the introduction of highquality ground engaging tools( GETs) and installation kits for truck beds and buckets.
Schlam’ s expansion follows the successful establishment of production facilities in China and Mexico, which, in addition to Schlam’ s Australian facilities, ensures the company’ s global manufacturing hubs are close to all major markets.
Schlam Chair and Chief Executive Officer, David Haslett, said:“ We’ re responding to customer demand in markets that are relatively new to Schlam to ensure we’ ve got the right teams, resources and products to meet their needs. This results in more comprehensive load and haul solutions for customers globally.”
The range of Barracuda loading attachments is being extended to support all models of machinery over 100 t. In addition to providing buckets for backhoes, wheel
