Three impact points. Improved feel and reduced cam-out. By increasing the number of impact points from the conventional two to three, the hammer's claws deliver three precise impacts per rotation, reducing vibration. This achieves a better feel and minimizes cam-out. Ideal for low-load fastening tasks such as short screws and thin screws. Additionally, it features a mode switch function to support a variety of tasks. Class-leading screw tightening speed. Under high load conditions, the number of impacts is automatically controlled, skipping one claw of the hammer to deliver 1.5 impacts per rotation, which increases the hammer's travel distance and dramatically boosts impact energy. This achieves the fastest screw tightening speed in its class and the highest tightening torque in its class. Perfect for tightening long lag screws and thick screws. Class fastest. - Tightening speed: approximately 20% UP - Conditions: Lag screw φ5.3x120mm in lauan wood, no pilot hole. Class maximum. Tightening torque: 172N•m. Improved cooling efficiency and optimal airflow design. Efficiently cools the motor and hammer case, enhancing durability. Increased work efficiency with center balance design. By positioning the center of gravity near the middle finger of the handle grip, balance is improved, reducing the burden on the operator. Dustproof and waterproof. Special airflow window structure that makes it difficult for dust to enter and protects key components.

Overview There is energy available here as well. Would you like to utilize untapped hydro energy? Currently, as global efforts to address the issue of global warming are underway, there is a growing demand for the effective use of clean, untapped energy that has a low environmental impact and fewer resource constraints. Hitachi proposes an "Energy Recovery System" that recovers untapped hydro energy, which has been overlooked until now, into electrical energy using a power generation water turbine. The recovered electricity can be used to reduce the power for equipment or for various applications such as lighting and hot water supply. Since the revised Energy Conservation Act came into effect, the demand for energy conservation has been increasing. Hitachi responds to customer solutions with the Energy Recovery System. The "Energy Recovery System" achieves high-efficiency energy recovery through optimal rotational speed control of the turbine based on the effective head, and it adopts a generator-integrated inline turbine that can be installed in the middle of piping, realizing a compact and small design. This product, which combines our fluid technology, motors, and control technology, is characterized by its ability to achieve high recovery of untapped energy with the aim of reducing environmental impact. High efficiency with an energy recovery rate of approximately 60% For example, with an effective head of 35m and a flow rate of 2.8m³/min.

Overview Electricity generated by solar panels cannot be sold 100%. It is lost as waste while connected to the grid. Additionally, during non-generating hours (at night), electricity is purchased due to standby power and other factors. Hitachi's solar-specific amorphous transformer, Super Amorphous Zero CE, significantly reduces power loss during selling electricity with ultra-high efficiency. Furthermore, by minimizing the transformer's standby power (no-load loss) to the extreme, it contributes to improving overall business profitability in the power generation sector.

Overview Drive generation. A next-generation hoist that returns regenerative energy to the power supply is now available. Realizing effective use of energy The regenerative power generated during lowering is returned to the power supply line through electronic circuits, achieving effective use of energy. By returning the power (regenerative energy) that was previously wasted as heat through discharge resistors back to the power supply, it can be effectively utilized in other equipment. Equipped with a hoist-specific regenerative converter Replacing the discharge resistors of conventional inverter hoists, it is equipped with a regenerative converter customized specifically for hoists. No need for harmonic countermeasures Standard equipped with a power supply coordination reactor, eliminating the need for harmonic countermeasures. Existing models can also be retrofitted Existing models (Super V4 series) can be modified with a retrofit unit.

Overview The newly improved hoist with enhanced maintenance and convenience significantly contributes to the streamlining, labor-saving, and efficiency of production lines. Increased Lifting Speed The lifting speed features a standard dual-motion system with low-speed/high-speed options to accommodate precision tasks such as mold alignment. Both the lifting speed (low/high) and the traversing speed can be controlled continuously within a range of 1 to 1/10 speed. Additionally, by adopting the "Dual Drive" method, where two reduction gear motors are directly connected to the drum, the lifting speed under light load conditions can be set to twice the rated speed. This balances delicate transport and efficient loading operations. Effective Use of Energy A standard "regenerative converter" is equipped to return power (regenerative energy) that was previously wasted as heat through discharge resistors back to the power supply. By returning the regenerative energy generated during lowering to the factory's power line via electronic circuits, energy can be effectively utilized in other equipment. Standard Load Swing Suppression Function In addition to conventional cushion start and stop, the automatic execution of follow-notch operations reduces load swing (less than 1/4 compared to our inverter hoists). Standard Function for Saving Operating Data to USB This includes the number of starts based on load and operational data.

The variable speed push button has a two-stage motion. The first stage is set for low speed, and the second stage is set for high speed. Both low and high speeds can be independently set to any desired speed. Reduced vibration of the suspended load. The cushion start and stop reduce the impact during startup and stopping, thereby minimizing the vibration of the suspended load and the shock to the building or crane girders. Smooth operation reduces load sway. Smooth acceleration and deceleration help to reduce the sway of the suspended load. Impact reduction on mechanical parts. Braking occurs when the motor's rotation is low, resulting in less wear on the lining and reduced impact on mechanical parts such as wire ropes, sheaves, couplings, and gears, thus extending their lifespan. Standard load sway suppression function. While the inverter drive reduces the sway of the suspended load, inertia can cause sway during stopping. Operators can perform follow-up operations, known as "chasing notch" operations, to suppress load sway based on how the load sways, but this can be challenging for inexperienced operators. Therefore, even without performing chasing notch operations, the automatic function equivalent to chasing notch operations can suppress the occurrence of load sway, providing a load sway suppression feature.

Overview Cut unnecessary energy from unexpected accidents in advance. Significantly reduce testing costs by extending annual inspections. For the preventive maintenance of essential electrical equipment in factories and buildings, trust the Hitachi Low Voltage Insulation Monitoring System. Benefits of Introducing Insulation Monitoring - 24-hour monitoring eliminates the need for power outages. - Early detection of insulation deterioration signs allows for proactive management (preventive maintenance). - Insulation resistance testing during annual inspections can be reduced. Economic and Space-Saving - The use of multi-circuit insulation monitoring units simplifies installation and saves space. Additionally, costs per circuit can be reduced. - The absence of a voltage superimposition device makes it economical and contributes to space-saving without affecting circuits or loads. Stable Operation with the Same Detection Method as Residual Current Devices - Similar to proven residual current devices, this reliable method directly uses the magnitude of detected leakage current. - For determining insulation status, the "fundamental wave component of leakage current," from which harmonic components have been removed, is utilized. Appropriate Monitoring of Effective Leakage Current Based on Circuit Type - Single-phase and three-phase - Δ connection (S-phase grounded): Monitor using the fundamental wave effective component I0r, which shows a large value. - Three-phase - Y connection (neutral point grounded):
