Description
Product Lines: Industrial Tools
Key Features and Functions:
- Brushless Motor Technology
- Equipped with a maintenance-free brushless motor, ensuring low noise operation and an extended service life.
- High Synchronization Precision
- Delivers consistent flow output across all points, achieving synchronization accuracy of up to 5% under uniform load conditions.
- Flexible Control Options
- Each point can be controlled individually or collectively, allowing micro-adjustments during lifting/lowering operations for enhanced precision.
- Dual Safety Valves
- Features an internal safety valve and an external pressure regulating valve for reliable overload protection and system stability.
- Upgradable Configurations
- Optional accessories include lockable casters, air-cooled radiators, protective frames, rain shields, and more to adapt to various working environments.
- Load Lowering Valve for Safety
- Every point is equipped with a load lowering valve, ensuring zero pressure leakage during lifting and enabling slow, controlled, and safe descent of loads.
Operation Handle Guide (4-Point Hydraulic Pump Example):
- Start/Stop Control
- The handle includes two buttons: one to start and one to stop the hydraulic pump motor.
- Rotary Knobs for Precision
- Four rotary knobs are integrated into the handle, each corresponding to one hydraulic point. Every knob has three positions:
- UP: Activates lifting operation.
- HOLD: Maintains the current position.
- DOWN: Activates lowering operation.
- Four rotary knobs are integrated into the handle, each corresponding to one hydraulic point. Every knob has three positions:
- Operational Workflow
- First, set the desired operation mode (UP/HOLD/DOWN) for each point using the rotary knobs.
- Then, press the motor start/stop button to execute the commands simultaneously or individually.
Think Safety
Manufacturer’s rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!
