Manual trackers are generally screwdrivers with simple structures, but they are compact and slow and are mainly used on cranes for small, medium-sized or temporary applications with small wind cover。
Manual trackerStructure:
The manual tracker is a combination of hand wheel and silk rods that combine components such as special nut clamp。
Manual trackerRationale:
When the hand wheel rotates, the lead wheel turns, leads to the operation of the chain through a special nut and continues to go down, forces the lower side of the clamp to move to both sides of the orbit for wind-proof purposes. When the wheel rotates backwards, the clamp is first released, and the wheel continues to rotate, the connector is lifted until the unit on the special nut touches the trip limitr, which, because it is often open, is connected to the power, the large car is operated and, conversely, the power is cut and the large car is prohibited from running, thus the car is locked。
Manual trackerCharacteristics:
Practical, easy to repair。
2. A hand-held tracker has a good tuning function, thus resolving the major difficulty of the market product being unable to function normally when it is on the wheel, and whether the wheel is on that side of the orbit, it can be calibrated to the orbit. This involves a manual orbital tracker, which has a screw at the lower end of the frame, which acts as a pair of the left and the right plates on the left and the right sides of the orbital symmetry, and which is directed in turn through the top of the left and right sides, and is fixed on the frame, with a simple structure, small parts and easy to install; it is operated by rotating the screws to separate the right and the left and the orbits, and then by inserting the plugs into the plugs, the process switches are opened so that the crane is functional, which needs to be pulled out, the process switches closed and the crane cannot be activated. The manual tracker therefore has characteristics such as simple structure, ease of use and strong self-locking capability, and is not subject to horizontal external load conditions。
Vendor hint:
1.There are many different types of crane parts: one product has several different sizes, and it is not possible to ensure that the crane parts you need are used in the same way as the crane parts sold at the store. So before you shoot, please (contact us) inform the owner of the store of the main specification sizes you need, and make sure that the crane parts you need are the same size and type of crane parts you want. For example: length, width, height, internal and external diameter, teeth, speed ratio, tons, etc. To avoid errors, you have to film the product you need against the object。
2The seller was not liable for the incorrect recording of the product because the buyer failed to provide the size of the model. Costs incurred in returning goods and replacing products are borne by the buyer itself
3The company's products will not be replaced except for quality issues
