Challenges to optimize yard space utilization, step up water and material recycling rates, and lower process-waste disposal costs are driving concrete producers’ adoption of equipment well established in the mining business. Filter presses used in tandem with concrete reclaimers accelerate the water recycling loop and limit landfill-bound material to low-moisture cakes of primarily cement fine composition. Along with the McLanahan Concrete Washout System on the preceding pages, Concrete Products examines additional filter press offerings.
Caterpillar’s new 926M, 930M and 938M models build on K-Series predecessor loaders—924K, 930K and 938K—with engineering refinements that include new power and exhaust treatment packages meeting Tier 4 Final emission standards, plus standard or optional features aimed at improved value, operator comfort and safety. With the M-Series introduction, the nomenclature for the smallest model in the family changes from 924 to 926, reflecting the increased capabilities of the new model, compared with those of the 924H and 924Hz. All three new models have increased engine power and higher tip loads than machines they replace.
