The W12 series products are stage specific electric hoists, also known as self climbing electric hoists, which can achieve two lifting methods: front hanging or reverse hanging. They are mainly suitable for fixed installation in the field of commercial stage construction, shopping mall banner lifting, and are used for stage construction/mobile performances, stage scenery, sound, and lighting layout banner lifting.

　　It can be designed with single control or multi machine linkage to meet your various operational needs. To achieve ultimate lightness, the entire machine casing is made of aviation aluminum material. The overall strength of the machine can reach a safety factor of 8.2 times. Adopting two 14n. m electromagnetic brakes and a dual brake system to ensure product safety and brake accuracy, minimizing errors during synchronous control. The protection level is IP56, with waterproof design, and has completed the test of soaking in rain and water. Through self-developed integrated circuit boards, the product comes with upper and lower limit switches, and is equipped with adjustable limit blocks to adjust the limit distance according to needs, saving a cumbersome control line.

　　How to ensure the safety of the construction of electric hoists on stage

　　As an important tool for building a stage, the stage electric hoist not only needs to be inspected before use, but also needs to make a series of preparations for the on-site situation while ensuring that the stage electric hoist is normal, to ensure the stability of construction. These preparations mainly start from these points.

　　① Selection of power supply voltage: The rated voltage is required for the stage electric hoist. The magnitude of this voltage should be known in advance. The correct voltage can ensure the normal operation of the stage electric hoist, otherwise it will bring unnecessary trouble.

　　② Selection of suspension points: The selection of suspension points is a crucial step to ensure the firmness of the suspension point beam, which can withstand the weight of electric hoists and heavy objects, and ensure a good layout.

　　③ Be careful during the installation process: During the installation process, there are usually command personnel to ensure the placement of sound and lighting, as the installer cannot observe the installation position on their own. Therefore, the commanding personnel must observe carefully, stop the installation deviation in a timely manner, and make adjustments.

　　The above three points are the preparations that need to be made during the process of using a stage electric hoist to build the stage.
