河井ローダー建設 List of Products and Services

Registered in the Hokkaido New Technology Information Provision System! 【Features】 ○ The amount of work increases compared to backhoe-type breakers. ○ There is less vibration than backhoe-type breakers, reducing the impact on the surroundings and achieving a similar effect on noise. ○ It demonstrates superior capability, especially on rock formations without eyes, compared to backhoe-type breakers. ○ It can be used not only on rock formations but also on concrete. ○ The excavated rock is finely crushed, allowing it to be used directly for temporary roads, etc. ○ Work efficiency has improved by about 20% compared to breaker types. ● For other functions and details, please contact us.

• Rock drills, demolition machines, and excavators
• Concrete Machinery

☆NETIS Registration☆ This is a towed type gravel removal machine, as opposed to the self-propelled gravel removal machine we introduced. 【Features】 ○ Compared to the conventional stone loader type gravel removal process, which involves four steps: gravel extraction → gravel loading → (gravel transportation) → leveling, the pin roller type gravel removal process consists of two steps: gravel extraction, gravel loading, and leveling + gravel transportation. ○ The construction time for the pin roller type is 0.4 hectares per day, demonstrating four times the capacity. ○ In terms of quality, the vertical movement of the pin roller and operation solely by travel eliminates soil layer mixing, unlike the stirring and separation caused by buckets in stone loaders, and resolves inconsistencies in the excavation surface due to the operator's skill. ○ In terms of the environment, it produces no noise from impact sounds. ● For other functions and details, please contact us.

☆NETIS Registration☆ With a two-step process of gravel collection, gravel loading, and land leveling + gravel transportation, the pin roller type demonstrates a capacity of 0.4 hectares per day, which is four times more efficient. 【Features】 Work Process ○ The tip of the screen is designed to be inserted into the soil. ○ The inserted pin roller rotates at high speed against the soil layers. ○ The high-speed rotation of the pin roller crushes soil and weed debris, which then passes through the pins and is returned to the soil layer. ○ Only stones are removed and discharged into dump trucks via a conveyor belt. ● For other functions and details, please contact us.

• Earthworks
• Pile and foundation work

It is registered in the Hokkaido New Technology Information Provision System. 【Features】 ○ You can freely choose between electric or engine-powered drilling, as it is a 2-way system. ○ In deep drilling, as the depth increases, air circulation is needed due to exhaust gases, but this machine is electric, so there is no need for that. ○ It produces less vibration compared to breaker-type backhoes, reducing the impact on the surroundings and achieving similar effects on noise. ○ It can be used not only on rock but also on concrete. ○ The excavated rock is finely crushed, allowing it to be used directly for temporary roads, etc. ○ Compared to breaker-type machines, work efficiency has improved by about 20%. ● For other functions and details, please contact us.
