OVERRHEAD TRACK COMPOSITE SYSTEM

INSTRUCTION MANUAL

A: The overhead rack composite system uses aluminum alloy, double box girder shaped strips (which are “ 王” shaped in section ) for its main and branch tracks. These come in a complete range of specifications and can be installed to meet the needs of all sizes of TV/ photography lighting frames. It is most common for the tracks to be laid out in a “knots and crosses” grid. Any number of additional branch tracks can also be added. Each boom adjuster can be raised or lowered, and each lamp can be freely moved forwards or backwards along its track. The system does away with the use of fixed angle lighting. and tidies the electrical running over the lighting frame. It provides a lighting function that can be tailored to your requirements. The system has a wide range of applications within the bridal photography, portrait, advertising and video recording fields.

B:  Preparations prior to installation

Choose a suitable site within the photography / TV studio. Attach fixing plates at even intervals along two fixed tracks (see Fig. 1). Bore a series of holes corresponding to the bolt positions in the fixing plates (see Fig. 4: in general one hole every meter, a standard 4m track requires 4 fixing plates, 8 fixing plates in total). If your studio has a concrete ceiling. use a □ 10 drill bit to drill the holes and □ 8 expansion bolts. If your studio has a wooden ceiling. use a □ 3 drill bit, and □ 5 self-tapping bolts. Secure the fixing plates, along with the fixed track, to the ceiling. The width between the two fixed tracks should not exceed 2m.

Attach 2 double runners to each moveable track. Then attach the runners, along with the moveable track, to the lower channel of the fixed track attached to the ceiling. Fit safety stopping bolts to either end of the two fixed tracks. The channels on the moveable track should also be fitted with stopping bolts. Fit the expandable boom and electric cable onto the lower channel of the moveable track.

Check that no errors have been made in the above steps. The attach the lamps to the bottom of the boom. Thread the lamp and the boom together using a safety line, to prevent the lamp being damaged if it drops off the booms. Adjust the adjustor on the booms, according to the weight of the lamp. The booms can be used to position the lamp at any point in the air. Attach the electric cable fasteners to the cable rod on the boom. Once this is completed, the power supply can be connected and the lamp put into use.

C:  Item for attention following installation

The bolts must be securely fixed. In particular, stopping bolts must be tightly attached, to prevent the booms running off the end of the moveable track.

The lamp mains supply line must be fixed according to the length from the ceiling to the boom and have sufficient play. A twin sheathed mains cable should be used.

Each boom should carry a lamp no heavier than 10kg, to prevent overloading the system.

The ceiling should be no more than 3.2m above the floor.

D:  Operation and common maintenance

Only once all parts of the assembly have been checked and found to be in proper order, may the mains supply be connected and the system used.

The vertical travel of the lamps is obtained by pushing up or lowering the boom. The lamps vertieal position can then be fixed by tightening the knob on the expandable boom.

Lamp horizontal motion is achieved by pushing or pulling the boom along the moveable track. Moreover, the moveable tracks themselves can move along the fixed track. During daily use, all bolts and nuts should be regularly checked to ensure they are secure they are secure. In particular, check the stopping bolts at either ends of the moveable track and fixed track, to ensure tracks or boom cannot fall off. Check for any signs of damage on electrical wires. If worm, replace with cables of the same specification, do not replace with conventional cables. This product has a one-year warranty period, during which any quality problems shall be repaired for free. Customers must pay for repairing any damage caused to parts for which they are responsible.
