جديد مطرقة هيدروليكية Caterpillar Straight

This straight hydraulic breaker is a heavy-duty hammer designed for 18–22 ton excavators for rock excavation, concrete demolition, road ripping and foundation trenching. Unlike triangle side-mounted breakers, the straight top-type design transfers impact force in a straight line onto rock and concrete. It minimizes bending stress on the excavator arm and reduces structural wear of your host machine.
The streamlined straight body brings outstanding operator visibility. When working in narrow trenches, compact foundation zones and confined demolition areas, it can easily reach hard-to-access spots where side-type hammers are difficult to operate. Built with heavy-duty alloy steel cylinder and chisel, this breaker maintains stable impact output under continuous heavy loads. It efficiently breaks bedrock, large boulders and reinforced concrete, ideal for quarrying, highway reconstruction and urban demolition projects.
Equipped with anti-blank firing protection, the hammer prevents damaging dry hits when nothing is under the chisel. This key protection mechanism safeguards the piston and internal seal components, cutting unexpected breakdowns and lowering maintenance costs. The hydraulic system is well optimized to adapt to different host machines. It sustains steady striking frequency without overheating even during long shifts of nonstop breaking.
Not limited to CAT320B! This straight breaker has wide compatibility and fits most mainstream 18–22 ton excavators of various brands. Installation is simple and fast. Paired with a quick-change system, operators can switch between digging bucket and straight breaker on site within minutes. One excavator can handle earthmoving and rock-breaking jobs, removing the need to rent extra equipment and saving transport and labour expenses. Its simple internal structure facilitates routine inspection and spare part replacement.
This straight hydraulic hammer is widely trusted by contractors for tight-space breaking work. If your projects involve trenching, foundation removal or rock crushing in limited working areas, this straight breaker is your solid and cost-effective attachment. It delivers stable power transmission, less arm wear and consistent breaking performance for all your tough demolition tasks, no matter which compatible excavator brand you use.
