Pneumatic hoist structure
Pneumatic hoistStructure contains
1.Lifting and lifting mechanism
2.Running, walking mechanism
3.Drive, gas distribution system.
Pneumatic components including the pneumatic motor, structure, brake, lifting chain, hook assembly and so on, the lifting system is mainly done by main control valve on the rise and fall of lifting heavy objects, placed on the pneumatic hoist limit device can ensure the safety of the hoisting operation, in the distribution system is mainly on the pneumatic hoist is compressed air as power source control road walking the lifting of gourd, for the main characteristics of pneumatic hoist can be flammable and explosive environment, running speed is very fast, can accurate positioning, the fuselage device for overload protection device.
Overload protection: when the working load exceeds the rated load, overload protection will stop the machine working, ensure the working life of the machine, and automatically fail.
Sprocket: high precision wear-resisting sprocket ensures smooth lifting and lowering of the chain in the middle and long service life.
Planetary gear: accurate and effective speed ratio control of two-stage reduction mechanism.
Pneumatic motor: low air consumption, low weft protection. High torque, faster transmission speed.
Brake mechanism: forging brake disc effectively prevents the danger brought by spark, its movement is sensitive and reliable brake, to ensure safe and reliable operation.
Muffler: the internal muffler effectively reduces the exhaust gas noise value less than 82 db.
Distribution valve: precise piston movement control in and out of the air so as to achieve the internal regulation of infinitely variable speed
Pneumatic hoistThe external structure
Air break protection: when the air source is suddenly cut off, the brake is automatically locked by the power transmission part directly controlled by the brake, so as to prevent the load hanging in the air from falling freely.
Chain: T8 class, aging resistance, contain enough alloying elements alloy steel calibration chain, its safety factor is 5 times the standard force.
Limit device: when the load is lifted to the top, the limit quickly stops the load from lifting and immediately opens the brake device to ensure safety.
Chain storage bag: can be customized to meet the chain storage, or use metal chain box.
Standard grade hook: standard 360-degree rotating hook or copper plated hook for special explosion-proof occasions can be selected. The safety factor is 8 times of the standard tension.
