Q:The hydraulic platform can't rise. Why?

There's a problem with the control system, maybe that part of the circuit is in bad contact

Q:Which mobile shear fork lift is better

Mobile shear fork lift There are four major systems, The mechanical structure system,

Q:What hydraulic cylinder is used

It is better to use hydraulic welding double acting cylinder.I hope my answer will help you.

Q:There is no elevator on the 7th floor of the home to install a lift or lift

Comrade as an ordinary elevator work I tell you, the guerrillas installation of lifts is commonly used or is directly discarded ladder refurbished, safety exist great hidden trouble. If you see your family's life as a game, you can take a baidu elevator and install team.

Q:On the principle of hydraulic lifting platform, using the foot switch control, when stepping on hydraulic pump, hydraulic platform, depressed when, what is under the control of the hydraulic cylinder pressure?

There is a very commonly used in oil overflow valve, its role is: regardless of the flow of oil, only to a certain pressure to open (internal spring, spring elastic adjustable), also have the effect of pressure.

Q:What should the chain's main elevator be aware of when installing the chain

The installation of the power system traction equipment interface must be done. According to our experience, part of the accident was caused by the failure of some manufacturing enterprises to do the right thing with the traction power and the host mesa.

Q:How do you remove the horizontal universal elevator milling cutter

When the milling cutter is removed from the vertical milling machine, the lever nut must be released and then the end of the rod is gently tapped. ; You should not release too much, as long as you have some loose space. When you release too much, the thread connecting the rod and the milling cutter is too short, and when you tap, you slip and even drop the knife.

Q:Hydraulic platform repair work instruction book, trouble which big man helps to provide

Remove and disassemble the descending valve, blow the plunger through compressed air and then load and resettle. Remove the hydraulic oil, tighten the connector and remove the oil strainer and clean it with compressed air, then put it back in the tank and connect the line. Do not use old oil for new oil

Q:To make a four trapezoid screw lifting up seven tons of lifting platform should be matched with the straight screw and motor

Can be judged according to the accuracy requirement of lead screw grinding or rolling, depending on the load and its acceleration can choose servo power right away and screw the maximum load capacity (do longer engineers can intuitive judgment the diameter of the screw and large), so that you can around the power of the servo motor of the different speed and different lead screw to match, so there will be several different schemes: high speed servo motor with small lead screw (sometimes deceleration machine), big inertia servo with lead screw. Under the condition of the machine cost to determine, from two to three scheme choice, choice of method is to choose low cost, with high stability, cost effectiveness and cost are the same common and suppliers have a spot. If the single from choose the ways of the servo and screw usually have an intuition, like 3000 revolutions of servo goods on the market the most sufficient, screw is according to the supplier's inventory.

Q:How to automatically lift up and lift

There is a manual lifting table, with the hand rotating black knob, lifting the platform clockwise, reducing the counterclockwise elevation.
