Mechanical jackThe mechanical jack reciprocally pulls the handle, pulling the pawl pushes the ratchet gap to rotate, and the small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be raised or lowered to achieve the function of lifting pulling force.
Principle of hydraulic jack
In a balanced system, the pressure exerted on the smaller piston is smaller, and the pressure exerted on the larger piston is also larger, so that the liquid can be kept still. Therefore, through the transfer of liquid, different pressures on different ends can be obtained, so that a transformation can be achieved.
Advantages of conveyor belt hydraulic jacks:
1) The price is reasonable, and most people can bear the cost;
2) It is easy to learn and simple to operate;
3) Different model(1#2#3#4#5#6#) stainless steel fastener can be used;
Conveyor belt stainless steel fastener hydraulic jack operating manual
1. Before operating the jacks, first insert the notched end of the handle into the release valve, turn the operating handle clockwise until the release valve is closed. Do not train oner to tighten the valve.
2. Insert the operating handle into the socket and the ram is steadily raised by the up and down movement of the handle and the load is thus raised the ram will stop rising when the required height is reached.
3. Lower the ram by turning the release valve.
counter-clockwise with the notched end slacken it slowly when a load is applied or accidents would occur.
4. Before operating, estimate the weight of the load, Do not overload the jack beyond its rated load.
5. Select point of action according to the gravitational center place the jack on the hardness ground If necessary, place a hard plank under the jacks so as to avoid tottering or falling during operation.
6. When more than one jack is used at the same time it is important to operate the different jacks at an equal speed with an equal load. otherwise, there is the danger of falling of the entire fixture
