The other salient features of this versatile product are:
- Adopting the most advanced VF speed control device and microcomputer programmable logic controller
- Step-less speed control which helps eliminate the concussion during start-up and braking, steadies the operation and ensures automated leveling.
- Adopting open loop VF control, the speed precision can reach +_ 2~3%. Realizing the accurate low speed positioning of the hoist, thus avoiding slipping during downward stopping of the hoist.
- The VF system which has current restriction function, suring lower current in motor start-up and reduces the concussion to power supply apart from the energy consumption at site. This system also has the over voltage protection, low-voltage protection, over-current, overload and anti-stalling protection functions
- The steadiness during operation, mitigates concussion to mechanical parts, reduces wears of rack, pinion and the brake, prolonging the life of these parts.
