FAQ

Simple manual lifting mechanism, a nut a bolt can
The lifting device does not have to be bearing, the screw is long, it is fixed in the round hole of the bottom panel, and the spiral of the screw is lowered by the spin of the screw
What is the use of a silk pole elevator?
It can be used in single or combination, which can be controlled by a certain degree of accuracy, which can be driven directly by electric motive or other power. It can also be manually, with the maximum input speed of 1500r/min, the maximum speed is 2.7 / min. There are different structural forms and assembly modes, and the height is customised according to the user's requirements. The change device can be self-locked.
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.
There are several reasons for the hydraulic cylinder oil leak on the elevator
The sealing part of the seal is worn out to buy two oil seals according to oil cylinder model to change to be good also a few dollars
Which mobile shear fork lift is better
Mobile shear fork lift There are four major systems, The mechanical structure system,
There are several categories of mobile elevators
The mobile elevator can be chosen as two phase, three phase, electric bottle and diesel engine for lifting power, and explosion-proof electric machine and electric appliance can be used in special places. The elevator control system is controlled by electric, lower control, and controlled by hand, electric or remote control. This series of elevator has a mobile and flexible, steady lifting, large capacity, easy to operate etc, mobile hoist is widely used in factories, grain depot, airports, gas stations, organs, wharf, wild power, street lamp maintenance and architectural decoration and other industries. The mobile elevator can be made according to the user's requirement.
What hydraulic cylinder is used
Both of the above are very good, and I personally think that the rear cover of the cylinder should be cushioned
Hydraulic platform repair work instruction book, trouble which big man helps to provide
The maintenance system of elevators is maintained every month. Roller, intermediate shaft and bearing, oil cylinder pin shaft and bearing, arm hinge shaft and bearing, etc. All parts are filled with lubricating oil to extend the life of the bearing.
