Pay attention to the work of large tonnage hydraulic cylinder

Engineering of large tonnage hydraulic cylinders using the public process should be in strict accordance with the hydraulic cylinder rated lifting weight, each lifting height shall not exceed the symbol on the piston, such as no sign, each lifting height of not more than three quarters of the screw thread or total piston length so as not to screw or plunger, all raised and damage to the jack.

To determine is not going down or can press down but will come out

If the first one is to return to the oil valve or piston rust should always be maintained even if you do not have to regularly maintain

The second is the hydraulic pressure oil tank into the air to gas hole to pull Jack across the rubber plug piston can be reset

With two or more than two sets of hydraulic cylinder at the same time when the top of an object, to unify the command and shout number, so that the action is consistent, different models of large tonnage hydraulic cylinder should be avoided at the same end use. Keep the machine clean, do well the construction of the construction site.
