Founded in 1937 in Japan, Toku has a straightforward mission: to lead with quality. This focus has driven them to develop advanced pneumatic and hydraulic technology, resulting in reliable products made in Japan. The company operates six factories, each with its own research & development (R&D) center, manufacturing unit, quality control, and training facilities. Their product range includes 25 hydraulic and pneumatic tools, automotive tools, and air hoists. In 2016, Al Marwan Heavy Machinery became the authorized UAE distributor for Toku's hydraulic rock breakers, enhancing the local construction, mining & quarries, and demolition industries with the high-quality hydraulic rock breakers and excavator attachments.
A hydraulic rock breaker, often referred to as a jackhammer, breaker, or simply a hammer, is a powerful tool commonly seen as a machinery attachment for excavators and backhoes. Its primary function is to break through solid materials like stone, rock, and concrete with ease. The size of a rock breaker varies to match different base machines, also known as carriers, and is chosen based on the type of material it needs to break. Toku's range of hydraulic rock breakers spans from the compact 75 kg model to the heavy-duty 5.1-ton version, offering solutions for a wide array of breaking tasks.
Hydraulic rock breakers operate through a straightforward yet powerful mechanism. At their core, they utilize a hydraulic system that pumps high-pressure fluid to a piston. This piston then forcefully drives a chisel that is in direct contact with the material to be broken. The significant impact generated by the piston-chisel interaction initiates cracks in the material, which are then expanded by moving the breaker.
The key to their effectiveness lies in the hydraulic pressure, which magnifies the impact force, enabling the breaker to penetrate even the most resilient materials. Additionally, this system grants operators precise control over the impact force, which is crucial for delicate operations or when working close to structures that require safeguarding.
The performance of a rock breaker is gauged by its operating pressure (measured in MPa or psi) and its impact frequency (measured in beats per minute, BPM). For instance, a medium-sized 2.8-ton hydraulic rock breaker typically operates at a frequency of 350-450 BPM.
Hydraulic rock breakers are specialized excavator attachments widely used in construction, mining and quarries, and demolition. In construction, they're essential for breaking through concrete foundations, walls, and other structures slated for removal. These breakers are also instrumental in clearing rocks and boulders for projects like road and bridge building.
In the mining sector and quarries, rock breakers facilitate the breaking of solid rock and ore deposits, streamlining the process of extracting valuable minerals. They are key in creating tunnels and access points within mining operations.
For demolition projects, hydraulic rock breakers play a critical role in dismantling structures and clearing debris. They efficiently break apart concrete, steel structures, and other materials, making them indispensable in the demolition process.
Toku's product lineup features a comprehensive range of machinery attachments comprising 15 hydraulic rock breakers, categorized into 6 mini, 5 medium, and 4 large models. In the UAE, Al Marwan exclusively supplies 4 models from the medium and large categories, tailored for heavy-duty breaking and ripping applications for construction and demolition, quarry work, and mining.
Standing at 4 meters, the TNB400LU2 is the largest in Toku's range of large hydraulic rock breakers. It operates at an impressive impact rate of 470 BPM, making it ideal for large-scale projects.
As the smallest model in Toku's large range, the TNB30K is equipped with a 140 mm chisel. This hydraulic rock breaker is particularly effective in breaking down big rocks into smaller fragments, which can then be further processed by crushers.
Belonging to the middle to large range, the TNB230LU is a box case hydraulic rock breaker designed to Toku's high standards of impact power and durability. It boasts a unique design, a maximum-sized piston, and an extended piston stroke for enhanced efficiency.
The TNB151LU2 is versatile, suitable for demolition and quarry work. This model is available with three different chisel types - moil point, flat, and flat end - to accommodate a variety of job requirements.
Toku hydraulic rock breakers stand out with their accumulator-free design, offering a streamlined, efficient, and cost-effective structure. One of the key features is the optional auto-grease system, which simplifies maintenance and cuts costs. This system taps into the high-pressure hydraulic oil from the base machine and automatically delivers the right amount of grease during operation. This reduces wear on critical parts like the chisel bushing and retainer pins, thereby extending the lifespan of spare parts and decreasing overall operational costs of the hydraulic breakers.
Toku hydraulic rock breakers are designed with three distinct bracket and box types to suit various operational needs. Firstly, the two-piece open box type, available for models ranging from TNB-08M to TNB-6M, is known for its lightweight construction and ease of maintenance. Secondly, the enclosed box type incorporates a silenced design, ideal for operations near residential areas, and is available for all Toku models. Lastly, the side-mount box type, designed for backhoe loaders, offers easier handling compared to traditional designs and is available for 14 different models.
Regarding tool selection, Toku breakers offer three chisel types: moil point, flat, and flat-end. The moil point chisel is effective for breaking reinforced concrete and large rock surfaces. The flat chisel is suitable for trenching and finishing slopes, providing a wedge action. The flat-end chisel is primarily used for crushing larger rocks into smaller sizes, applicable for boulders and concrete.
Toku hydraulic rock breakers combine efficiency and innovation, designed in Japan to tackle the UAE’s most demanding projects across construction, quarries, mining, and demolition. As the authorized UAE distributor, Al Marwan is proud to present Toku’s leading-edge technology in hydraulic breakers.
