Opal Series Machines

Opal series machine are light weighted medium range single jib Building maintenance Unit (BMU), it is roof mounted machine working either by traversing along the track/guide or fixed at designated levels, the roof machine will include steel chassis, structure and frame, the jib, the slewing mechanism, the spreader bar slewing mechanism and the housing for the hoisting mechanism.

Hoisting Option:

• Drum-winch hoisting type where the hoist is mounted on the counter jib of the machine, these option gives optimum result as it save counter weight and the machine become lighter and compact.
• Traction winch hoisting type where the hoist is within the working cradle, it is basic system with advantage of using the same power cradle with other system be it machine, monorail or davit by easy switching.

Traversing Option:

• Rail Track traversing on galvanized steel double rail track on the roof of the building joined via Concrete up stands spaced at intervals, in this we have advantage to depend on the machine loading to keep the counterweight less.
• Guide rail on concrete runway, the roof machine will travel along the leveled concrete pathway guided by steel angle, the machine is perfectly counterbalanced.

Function:

• Luffing of jib by hydraulic jacks
• Spreader bar to keep cradle parallel to façade (motorized/manual)
• Motorized machine slewing
• Complete Control are given in machine and cradle
