The ergonomic design further enhances operational flexibility, enabling operators to manipulate the equipment with more ease and precision, greatly improving productivity on the whole.
Quick Attach
The single-switch operation of an electric hydraulic actuator simplifies the design process because system interfaces are easier and can handle various electronic control systems, reducing the time and costs associated with designs. The system design also eliminates complexity in accommodating large bend radii for hoses by simplifying how hoses, valves, controls, filters, and switches are laid out, thus reducing design complication and costs.
Because an electric hydraulic actuator adopts few installation components, the installation process will be much easier. It is easy to retrofit and upgrade because the interface design of the actuator is better matched with the existing application systems than the traditional hydraulic systems. This reduces installation cost and time by about 20%.
Electric hydraulic actuators replace intricate, high-priced hydraulic systems that don’t have to be piped with long hydraulic hoses. The actuator system, independent of hose reliance, becomes immune to things like hose fatigue, rupture, and the risk of contaminants entering the operating system. A maintenance-free, lifetime-lubricated design offers increased system reliability and reduces supplementary maintenance costs by up to 15% for long-term operation.
Hydraulic actuators also enable the operators to change easily from one implement to another from their seats without requiring any extra workers. Besides, the mechanism liberates the operator’s cabin from two high-pressure hoses further enhancing working safety. Moreover, in this actuator, an in-built position interlock further allows a safer operation guaranteeing productivity and enhanced safety.
Hood Lift
Electric hydraulic actuators with integral clutches or limit switches provide end-of-stroke protection against over-travel damage. Its wide operating temperature range and ruggedness against shock and vibration result in a very stable operation in various extreme conditions, reducing the tolerance issues and design complexity. An actuator can also function as a hood lock, further simplifying system design and lowering overall design cost.
Electric hydraulic actuators come with different mounting accessories, which can easily integrate with a variety of electronic control systems and make the installation easy. Since actuators can be directly adapted to existing structures, the time and workload for installation are reduced, which further decreases the installation cost by about 15%.
These hydraulic actuators are designed not to weaken over time with low temperatures or with aging. This actuator supplies variable clamping force to avoid over-stressing the hood material and prolongs life. The operating costs are decreased due to infrequent maintenance and part replacement that results from the no-maintenance and durability factor.
Since electric hydraulic actuators hold their position when the power is off, there is no drifting or back-driving of the hood due to wind or any other factor. Even in the case of a dead or failed battery, the possibility for manual override, which enables operators to continue working the system in a highly practical way for improved safety. The actuator-assisted one-man lifting also means operators are in an easier and safer position to lift heavy weights, minimizing injuries from poor lifting and therefore making routine maintenance more manageable.
Hatch Open
Single-switch operation and easily interfaced multiple electronic control systems mean electric hydraulic actuators make life easier for the designer. When compared to conventional hydraulic systems, actuators require no consideration of hose bend radii or designing complicated hose, valve, control systems, filters, and switches, thus saving about 20% in design time and consequently costs.
Electric hydraulic actuators reduce installation components, therefore decreasing the complexity of the components and wiring, hence making the installation process simpler. The compatible interface design with existing systems ensures retrofit and upgrade are easy, further lowering installation costs and time. This can cut installation time as much as 25% compared to traditional hydraulic systems.
The hydraulic electric actuators replace complex and expensive hydraulic systems along with long hydraulic hoses, excluding the risk of hose fatigue and rupture, filter replacements to stop debris from entering the actuator operating system. Maintenance-free, lifetime-lubricated design provides years of reliable service without frequent maintenance, which considerably reduces operational and maintenance costs.
Hydraulic actuators with an electric drive allow operators to open and close the hatch without having to leave their seat. Working efficiency increases because operators do not have to frequently get out of their seat, labor costs are conserved, and there are lessened hazards to safety. Besides, high power density provides more flexibility in the design of the equipment and guarantees efficient and safe operation in high mechanical disadvantage with limited space.
Auger Fold
Choosing Rotontek electric hydraulic actuators over conventional hydraulic systems simplifies equipment design and provides greater flexibility. The overall design space is optimized due to the smaller installation size of electric hydraulic actuators. The end-of-stroke protection via either a built-in clutch or limit switches removes the need for complex hydraulic systems that reduce design complexity and costs.
Installation of electric hydraulic actuators is easier with varied mounting accessories and easy interfaces to different electronic control systems. Since actuators do not have to accommodate the bend radius of hydraulic hoses, they can be positioned in flexible ways, thereby reducing installation difficulty. The actuator’s position may optimize installation space, and no direct access is required for maintenance; this will reduce installation time and cost by about 20%.
The hydraulic actuators have great resistance to shock and vibration, with a wide operating temperature. That ensures reliable operation at extreme weather conditions and reduces system failures caused by harsh environments. With a maintenance-free design and lifetime lubrication system, an actuator can keep stable performance even after long time use, especially at low temperature to reduce the operational cost significantly.
Unlike hydraulic systems, electric hydraulic actuators will not leak hydraulic fluid; thus, no pollution or clean-up costs are incurred. Real-time feedback by the actuators’ mechanisms informs the operator if the auger is in place, ensuring an accurate operation. This cuts down on the number of adjustments to be made by the auger, hence reduced operator fatigue, reduced process interruptions, and improved productivity altogether.
Ladder Lift
The electric hydraulic actuators at Rotontek come with either an integral clutch or limit switches to provide end-of-stroke protection against over-travel damage. With a large operating temperature range and shock resistance, their performance is very stable in a wide range of environments, which reduces the problems associated with tolerance in the design process. The multifunctional nature of their design also allows these actuators to serve as ladder locks, hence simplifying system design and further reducing design costs.
There are various mounting accessories available for electric hydraulic actuators, and they easily interface with multiple electronic control systems. Optimized installation space and interface design make installation easier. Installation costs are reduced by about 20% due to better installation space and interface design. Besides, installation time and labor costs are saved by the elimination of complex hydraulic hose arrangements.
The efficiency of electric hydraulic actuators is quite high and does not deteriorate even after very long operation; moreover, at low temperatures, they do not weaken. They offer variable clamping force; hence, they effectively prevent overstressing or damage to the ladder material, prolonging its service life and reducing frequency of maintenance or replacement. The maintenance-free lifetime lubrication further reduces operating costs, making the whole system more economical.
Since the electric hydraulic actuators hold their position off, the ladder neither drifts nor back-drives as a result of wind or other influences. Allowing safe operation of the ladder. It also ensures that the system can be manually operated in case of a dead or faulty battery. The design of the actuator also enables one-man operation that eliminates the possibility of injury to operators through lifting heavy loads in awkward positions. This considerably reduces physical strain on the operator, along with increasing work efficiency and safety.
