The characteristics of a hand cranked roof: It is a mechanical lifting tool that mainly uses the principle of leverage to lift, so it can be used at any angle when there are supports or force points, making it very convenient for lifting, hoisting, and horizontal movement. Especially when items are lowered, it is easy to cause unnecessary trouble due to the inability to accurately control the pressure when using a jack. The components of a hand cranked roof are made of high-strength steel.Durable and secure,durable and long-lasting. Hand cranked roof collapse2A bracket support,Increased the lifting height in work.The hand cranked handle that spans under pressure adopts a foldable design,Open the handle during operation,When closed, the handle can be returned to its original position.Easy to use and space saving.
Usage of Hand cranked Shoulder Top 1The placement position of the hand cranked roof should be selected according to the center of gravity of the heavy object, so as not to overturn during lifting.
2When lifting and lowering, it is necessary to ensure that the entire area of the hand cranked roof or foot is in contact with the heavy object to ensure sufficient strength to prevent the heavy object from falling.
3The ground on which the hand cranked roof is placed should be sturdy.
4Before use, check for any card holders or abnormal phenomena. Only when everything is normal can it be used. Principle of Hand cranked Shoulder: Made of high-quality alloy steel materials,Compared to similar products, it is more sturdy and durable. As a commonly used lifting tool, the hand cranked overhead crane has a low starting point and mainly uses the lever principle for lifting. Therefore, it can be widely used in various occasions. The hand cranked roof can not only be used vertically, but also from various angles, achieving effects that ordinary products cannot achieve. The handle of the hand cranked roof adopts a foldable design, which is easy to operate, saves space, and is convenient to carry. Precautions for Hand cranked Shoulders 1Before using a hand cranked roof, it is necessary to understand the weight of the heavy object and the range of use of the jack. Overloading is strictly prohibited to avoid equipment damage and accidents.
2If the weight exceeds the rated lifting capacity, multiple overhead cranes need to be operated simultaneously to maintain even load distribution, consistent speed of ascent and descent, and stability.
3After lifting the heavy object, if it cannot be unloaded in a short period of time, an auxiliary pad with a height equal to the height of the heavy object above the ground must be added as a support under the heavy object. Hand cranked roof repair and maintenance 1The braking part should be kept clean regularly, and lubricating oil should be added to the pawl shaft frequently to make the pawl movement flexible and reliable.
2Frequently usedHand cranked roofMaximum time2—3Open the hood every month, wash it with kerosene, and inject lubricating grease.
3After use, do not place it in a high-temperature place to prevent lubricating grease from liquefying when exposed to heat. | |||||||||||||||||||||||||||
