SQ120 Soosan SQ120 Specifications & Technical Data (2010—2026)

The SQ-series Features

The advanced gas and oil percussion mechanism generates extra power by accumulated gas pressure which ensures a very reliable performance with a wide range of excavator pump conditions.

IPC & ABH System

The automatic anti blank hammering function (shut off) can be switched off or on. The operator can select the correct operating mode from high frequency with normal power to low frequency with extra power. With this advanced system, the operator may choose the correct mode in accordance with site requirements in a matter of minutes and with a minimum of hassle.

Enhanced Vibration Dampening

Meet strict noise regulations and allow more comfort for the operator. Further features are standard connections for underwater operation and an automatic lubrication pump.

Improved Vibration Damping System

Fully isolated power cell with premium quality urethane cushions and wear plates absorbs shock and vibration resulting in reduced wear.

Enhanced Performance & Productivity

By using a valve adjuster and an advanced power control system, SQ breakers can be adjusted to the excavator’s specifications and jobsite conditions to enable maximum productivity.

Service and Maintenance Friendly

The greasing port is located on the service panel. The service panel gives direct and easy access to key components without removing the power cell from the housing.

Special Features

IF Design Award – Winner. Advanced power control & anti blank hammering system. Premium quality materials. Enhanced performance, productivity and durability. Improved vibration-noise damping system. Robust housing including dust protector. Reduced noise levels.

Auto shut-off & easy start function

Breaker operation can be automatically stopped in order to prevent consequential damage to the power cell due to the blank hammering. Especially in secondary breaking or when the operator is unskilled. Breaker operation is easy to restart when soft pressure is applied to the chisel to the work surface.

SQ Line Silenced Series

The latest design from Soosan is the SQ breaker. It is the result of more than 2 decades of experience since the company's inception in 1984. Through active communication and monitoring of a large group of valuable customers from around the world, we have gained working experience from quarry, mining and construction industries. The SQ series are practically an innovated hydraulic breaker while maintaining the superiority of the percussion mechanism and easy maintenance of the existing SB series.

Advanced design technology for output energy

The well known powerful performance of the SB breakers is continued on the SQ line. With improvements to the percussion mechanism allows even more reliable and durable operation than the SB line.

Slim profile with robust structure

State of art slim profile for better visibility in narrow trench work. Hardox steel reinforcements at the lower end of the housing protect the casing and power cell.

Locking device for the tie bolt nut

This prevents the power cell from consequential damage that may be caused by the loosening of the tie bolt.
