Infinity dual purpose air winch is a pneumatic motor as a power, through the built-in planetary reducer to drive the drum, to achieve lifting or traction device, it is mainly used for land or offshore oil operations, it can be used for personnel lifting and utility lifting with two purposes.
Dual design factor, 8:1 design factor for personnel lifting ; 5:1 design factor for utility lifting. The minimum ratio of drum diameter to cable diameter is 18:1, which prevents cable wear.
1. The winch adopts the drum double support structure , the rope end fixed form is safe and reliable:
2. The winch deceleration system adopts a drum built-in planetary deceleration mechanism.
3. The brake system of the winch adopts two forms of built-in full stop brake and external hand band brake; Sealed automatic full disc brake, resistant to smoke, dust or moisture erosion, manual band brake, operator can implement braking;
4. The winch can realize two control forms of local operation and remote pendant control operation. Both control forms must have multiple safety protection measures such as slack line prevention, overload protection, limit protection, emergency stop protection, automatic cutting-off air brake and safe release.
a. Slack line prevention : when the hanging person or object contacts the support surface, the sling continues to fall for a small distance, the system will automatically stop the sling down, so as not to hurt people or objects.
b. Overload protection: When the load exceeds the rated load or set load, the winch will stop running to avoid serious injuries .
c. Limit protection: The control system is equipped with an upper and lower limit device, when the winch is lifted or lowered beyond the set lifting and falling position, the winch will stop running to avoid injury.
d. Emergency stop protection: When the operation is out of control or in other emergency situations, you can quickly press the "stop button" to interrupt the gas supply to avoid accidents. After the "stop button" is pressed, it has a self-locking function, even if the accidental spring can not restore the gas supply, only after pressing the "start button", the normal gas supply can be restored:
e. Automatic cutting-off air brake (built-in wet cutting-off air brake) : When the air supply system is interrupted due to pipe burst or other reasons, the winch will automatically brake to avoid injury or other losses.
f. Emergency Lowering: when the winch stops working unexpectedly, it should be able to lower the people or objects to a safe position.
The 2ton infinity dual purpose air winch mainly be used in oil fields (land, ocean), natural gas and other industries.
