SB50 Straight Type Hydraulic Rock Breaker Straight Hydraulic Hammer for 10–12 Ton Excavator

This compact heavy-duty SB50 straight type hydraulic rock breaker is a mainstream medium-small straight hydraulic hammer and standard universal SB50 excavator breaker, a practical lightweight hydraulic demolition hammer equipped with 100mm standard chisel for 10–12 ton diggers in municipal, road and indoor construction. As integrated straight cylinder hydraulic breaker without lateral protruding valve housing, this SB50 straight hammer adopts streamlined straight body design and built-in stable directional valve system, delivering balanced moderate impact force for concrete breaking, small rock splitting and foundation trimming. Compared with side-mounted SB50 breakers, straight compact structure occupies smaller space and can freely enter narrow construction areas such as basement, indoor room and narrow trench, with low vibration and stable continuous striking performance. It solves the limitations of side hammer in narrow working conditions, reduces vibration wear to excavator arm, lowers daily maintenance frequency, and is the most cost-effective straight hydraulic breaking attachment for medium-small tonnage excavator daily engineering operation.

Installed on the boom of 10–12 ton medium-small excavator, this SB50 straight type hydraulic rock breaker takes high-pressure hydraulic oil from excavator main pump as power source.

Hydraulic oil flows into the central straight cylinder cavity and pushes the piston to reciprocate vertically, continuously striking the top of standard 100mm chisel. Straight central force transmission concentrates impact energy vertically on rock and concrete without lateral force loss, improving breaking efficiency in narrow spaces. Built-in small accumulator stores redundant hydraulic energy to boost instantaneous striking power and smooth hydraulic pressure fluctuation. The streamlined straight body reduces lateral vibration offset, keeps stable striking track, and ensures consistent moderate breaking force during long-hour indoor and municipal construction.

This universal SB50 straight type hydraulic rock breaker is widely used for new machine assembly and old side hammer replacement of 10–12 ton medium-small excavators.

Main applicable working scenes: indoor house demolition, basement reconstruction, urban narrow alley road maintenance, small residential foundation breaking, garden rock cleaning, trench hard soil excavation. It is the optimal replacement attachment for side breakers that cannot work in limited narrow space, widely stocked for machinery repair shops, small construction teams, mini equipment rental companies and municipal engineering contractors.

Compared with traditional side-mounted SB50 hydraulic breakers, straight type SB50 rock hammer has targeted outstanding strengths:

1. Slim straight compact outline, access narrow construction zones such as indoor, basement and narrow trench that side hammer cannot enter, wider application range;
2. Central vertical force transfer, uniform stress distribution, lower cylinder wear and longer whole machine service life;
3. Small lateral vibration, reduce abrasion to excavator boom and hydraulic system, cut host maintenance expenses;
4. 100% compatible with all standard SB50 spare parts, accessory suppliers do not need extra separate inventory;
5. Stable moderate striking power, suitable for light-medium breaking, save excavator fuel consumption during daily municipal work;
6. Factory direct industrial-grade straight hammer, balanced performance with competitive wholesale price for small and medium batch procurement.
