Installation and trouble shooting of camera crane system

With the rapid development of TV technology. A wide variety of special functions and unique TV special equipment are rapidly approaching every TV worker. Mastering and using them skillfully has become an important means to increase program production means by professional TV workers and improve the level of program production. The camera rocker system is one of the large special shooting aids that are widely used in movie and TV shooting. It is popular with photographers for its unique location and angle changes and the unique advantages of motion pictures.


It belongs to the automatic control system of electromechanical integration, and its structure is rather complex. Taking Jiamei camera rocker arm system as an example, from the perspective of technology, we introduce our experience and experience in installation and operation.

Installation and trouble shooting of camera rocker system


system composition

A complete set of camera rocker system includes a heavy three foot frame and a track pulley, a front and back arm, a camera cloud platform, a stable steel cable, a video remote control, a power supply and a charger.

The heavy-duty three foot and rail pulley cars are the gravity support points of the whole system, and the weight is heavier. The purpose is to reduce the center of gravity and increase the stability of the system. The boom is mounted on the upper part, and can be rotated arbitrarily for X and Y axis.

The boom is divided into forearm, extension arm and rear boom. The forearm bar and the lengthening arm are relatively long and are connected by a number of fastening bolts. The top can be mounted on or below the camera cloud platform. The rear arm rod is short. The rear arm is composed of two bolts and the remote control handle can be installed at the rear.

And the hanging counterweight, the left suspension platform is equipped with power and charger, remote controller, monitor and so on.

The electrical control part is mainly composed of camera remote control, video surveillance and camera pan motion control.


Installation balance

A set of camera rocker system includes many parts that are self stitching when using, and the connection of electrical system. When the installation is installed, it must be carried out in order. The operation sequence is: heavy-duty three foot and rail pulley, forearm rod and extension arm.

The rod and arm stabilizer cable camera, the remote control monitor bracket, the remote control handle, the camera or the camera, the electrical control system, and the final suspension weight adjustment balance. When installing the front and rear boom, we need to calibrate each boom with a horizontal ruler.

The perpendicularity of the stiffener bar and the verticality of the camera tilt. To install the extension arm lever, the boom should be fixed and the tension cable should be tightened, so that the whole boom should not bend. It should also be noted that when installing, first install the camera and then hang the counterweight. When removing, first remove the weight and then unload the camera. Prevent the system from losing balance of gravity and accident.

Installation and trouble shooting of camera rocker system

In the use of camera rocker arm, due to the large range of activities, the operation should avoid collision lamps, props, people or other objects around, and immediately lock the horizontal and vertical bolts to ensure safety.

After the end of the installation, the balance of the arm and the rear arm should be adjusted. By increasing and reducing the quantity and weight of the hanging weight at the handle, the weight balance of the front and rear segments of the arm bar should be adjusted. The cameraman on the crank arm should be relaxed.
