​"Treasure" of Screw Jack Hoisting Industry

 Many lifting tools are used for transporting heavy objects, such as screw jacks/hand pulleys/lifting pulleys, etc. These lifting tools give different construction lifting projects, but screw jacks, which exist alone and can be used by multiple units, are good lifting tools, such as mechanical jacks, through manpower. The ratchet wheel is rotated in a way that drives the internal gear, raises the height of the jack-up head, and realizes lifting.           
 The structure of the roller bearing on its internal base is very precise, which makes the machine turn more stable and the speed of lifting more uniform. The  screw jack of good material can be said that it has not been bad for a hundred years. As long as you are not overweight, it will always be a lifting treasure.
 The function of lifting sleeve of screw jack can not be neglected. It is mainly used for lifting weights. It can not be neglected on screw jack.
 The lifting sleeve of the screw jack is made of manganese steel, the inside of which is made of copper nut, and the outside is prompted by red warning line to  prevent us from exceeding the height of safe expansion when using it. This is the safety limit standard of the screw jack.            
 The lifting sleeve of screw jack is made of cast steel, which is treated by quenching fire. It is very strong and durable, so the firmness of lifting articles can be seen very well.             

 Under the same tonnage, the lifting height of the high screw jack will be higher than the low lifting height (for example, the lifting height of the  20 ton high style screw jack lifting sleeve is 175 mm, while the lifting sleeve of the 20 ton low screw jack is 175 mm). The top elevation is 90 mm.)           
 For the lifting sleeve of screw jack, there is also a load standard. Do not overload the use of screw jack, which will make the screw jack unable to lift  or cause immediate damage to the jack, but also affect the damage of your goods.
 Here are five advantages of screw jack.
 1.  Wide range of use: It plays a lot of roles in building support, bridge construction, factory operation and wharf construction. It is not fictitious to say that it has a wide range of use.             

 2. High performance-price ratio: screw jack can be used without restraint on the direction of force, while hydraulic jack can not be used obliquely, so screw jack has a high performance-price ratio and is not restrained by the direction of force.            

 3.  Small size and big effect: the screw jack is small in size and easy to carry. It can be taken away and used by female comrades.            

 4.  Easy to operate: The jack is easy to operate in use, and the pressing handle can be directly lifted.            

 5.  Advantages of material selection: full cast iron fuselage, paint shell, built-in limit warning line in sleeve, tightly occluded precision steel ratchet combination, and stable thicker base can be purchased at ease.            

 Screw jack is a reliable lifting tool. In real life and construction production, screw jack is indispensable. Do you understand the five advantages of the above-mentioned jack? If you don't know anything else, you can call us to ask questions.
