On small lifting machine

About Small lifting machine a while ago, some units of production of small lifting machine, there are two problems: first, a lot of security risks: First, the structure is unreasonable, most of them using a non-standard motor with a gear box, decline in the use of the brake control, hanging heavy, heavy is likely in mid-air falling; the second is mostly single-rope hoisting, which means that the weight own weight borne by a rope. If the weight is slightly overweight rope breakage is likely to occur; the third is the timber, most of them using the pipe as a column, which appears when lifting the main pillar bending or cracking of things have occurred, for these reasons, they claim to lift 300 kg or 500 kg of small lifting machine, but in reality only lifting 100 kg or 200 kg less. Some buyers do not know the hidden secrets, with calf pull carts ", resulting in a lot of material injury crash event followed can only be installed in the house or on the roof using a crane, the use of a small crane to lock in a good house has been built. II. I produced a small lifting machine to overcome the above drawbacks. The first is the use of worm gear reduction box and sprocket chain of secondary structure, and using the national standard electrical outlet, which guarantees will not appear when the air hoist falling, even though it encountered heavy in the air power, the weight will not fall, make sure that the lifting safety; the second is the use of a pulley combination (ie fixed pulley and a movable pulley combination), saving half, with double rope lifting, put a rope weight change undertaken by the two ropes bear to ensure that the weight lifting; three main pillars of national standard seamless steel pipe manufacturing, to ensure the strength of the if installed indoors, can be highly from 2.6 to 3.5 m in any docking adjusted according to the interior. Outdoor use oblique rod, counterweight seat, indoor and outdoor use freely; four electronic display, manual and remote control combined; five easy installation and removal, handling up portable machine, the whole process of dismantling the entire ten minutes to complete, with fashion up close up when not in use. When the second is to use not only be installed in indoor and outdoor lifting, especially as it can be like a crane mounted on the ground can be constantly heightening the main column, lifting height freely, especially for high-rise housing construction. In short I produced a small lifting machine truly, do three guarantees: to ensure the safety of lifting, weight lifting ensure ensure easy lifting.
