Features Industrial Grade Product: Industrial grade products, resistant to falling and waterproof, oil resistance and acid resistance, don't worry that sweat and oil will affect the product. Wide Application: The hoist controller is suitable for cranes, conveyors, coal mining equipment, concrete pumps and other mechanical equipment. Good Anti-Interference Ability: 800MHz transmission frequency and good anti-interference ability, can withstand large force and the electric winch will not be deformed. Working In Harsh Environments: The performance is stable and reliable, meeting the industrial stability requirements. The products are rigorously tested before leaving the factory to meet the stringent requirements of working in harsh environments. Operation Safety: When the hook is lifted to the highest position, the weight limit contacts the upper limit bracket. The micro switch of the upper limit bracket can cut off the circuit and stop the motor to ensure safe operation Specification: Item Type: Hoist Controller Product Model: YU-6A Optional Voltage: DC24V, AC36V, AC220V,AC380V RF Point: 800MHz Features: Anti-fall, waterproof, acid and oil resistant Application Areas: Crane/Conveyor/CNC/Coal mining machinery/Generator start/Concrete pump/Grab/Other machinery Package List: 1 x Receiver 1 x Controller 1 x Transparent Bag 2 x Insurance Tube Note: New and old models are shipped randomly.
