The SB81 hydraulic breakers have been designed with many special features.
The advanced gas & oil percussion mechanism generates extra power by accumulated gas pressure which ensures very reliable performance with a wide range of excavator pump conditions.
Integrated power control & anti blank firing system allows you to choose from 3 different models.
auto shut-off easy start fuction, Breaker operation cab be automatishly stopped in order to prevent consequential damage to the power cell due to the blank firing, especially in secondary breaking or when the operator is unskilled.
Enhance vibration depending & sound suppression system. meet strict noise regulation and allow more comfort for the operator.
Power control &Anti blank firing system
H- mode : Long stroke & Extra power, ABF is OFF. This Mode used for hard rock breaking such as primary breaking, trench works andfoundation works where the rock condition is constant. The hydraulic hammer can be started without applying contact pressure to the working tool.
L-mode : Short stroke & Maximum frequency, ABF is OFF. The hydraulic Hammer can be started without applying contact pressure to the working tool..This mode is used for soft rock and semi-hard rock breaking.High impact frequency and normal power provides higher productivity andreduces strain on the hammer and the carrier
X-mode : Long Stroke & Extra power, ABF is ON.This mode is used for hard rock breaking such as primary breaking, trenchwork, and secondary reduction works, where the rock condition is not constant.·In ABF (Anti-blank firing) working mode, it switches off the hammerautomatically and prevents the blank firing ,as soon as the material is broken.The hammer can be easily restarted when minimal contact pressure is appliedto the working tool.
The ABF system reduces strain on the hammer and the carrier.
