General express regulations and instructions for lifting telescopic constant force hinged boom


Constant force hinge, commonly known as lamp lifting boom or lamp telescopic boom. Made of aluminum alloy material, fully sprayed, antistatic. It has the characteristics of light weight, good orientation and high strength. The constant force spring is made of imported special-made spring steel, which is specially treated, which is durable, anti-corrosion, and has a service life of no less than 50,000 times. It is characterized by compact results, easy installation, easy maintenance, convenient and flexible use, and it is the main equipment for hanging lamps in small and medium-sized studios.


General Civilization Regulations:


1. Before the hoist of the fixedly installed electric constant force hinged boom is installed in place, the geometric dimensions of the equipment installation foundation should be determined according to the construction drawing and the axis of the relevant building, and the geometric dimensions of the equipment installation foundation should be determined, and the allowable deviation of the plane position It is ±25mm.


2. When the constant force hinged boom is installed, it can be connected with a light hook or a light trolley. The diameter of the connecting pin shall not be less than 6mm, and the connecting pin shall have anti-falling measures.


3. The lighting cables and control cables of the constant force hinged boom should be bound firmly and freely along the hinged arm. Both ends of the cable should be connected by special connectors.


4. In the case of unbalanced weight of the two lamps, the crossbar should not be tilted significantly.


5. The load of the constant force hinged boom should have a certain adjustment range to match the weight of the lamp to be hung, and it can be reliably positioned within the designed full stroke range without up and down expansion.

Instructions for use:


Use the characteristic of the constant force spring to install it on the hinge, and match the corresponding lamp to realize the vertical lifting function of the lamp. When in use, the lamp can be made to stay at any height according to the needs, and there is neither sliding nor retracting phenomenon, so as to ensure accurate positioning. It can bear 2-15Kg, and the length is 1.5/2/2.5/3 meters optional.


The method of adjusting the balance of the boom by the constant force hinge: By adjusting the constant force springs on both sides to the upper and lower positions of the hinge shaft, the weight balance of the boom in the height range is achieved by the weight of the lamp. If the light weight of the lamp is light and the hinge boom cannot be pulled down, adjust the spring steel hook to the hinge axis stuck on the upper side, so that the spring tension is reduced, the tension and the lamp lifting balance are achieved, and the function of vertical lifting and staying at any height can be achieved. ; If the constant force hinged boom cannot raise the lamp, you need to adjust the spring steel hook to be stuck on the hinge shaft below to increase the elasticity and achieve the balance between the pull of the boom and the weight of the lamp.
