The Double start, dual Helical
Grooved Drums with four wire support
The main mechanical design feature that seperates the Q Hoist from
almost all other designs is the safety feature of the two double start
Helical grooved drums using four independent supporting wires. The
four wires each have their own groove along the drums and so suffer
no crushing as in pile winding systems. The double start ensures no
out of balance forces acting on the drums. This ensures long term
reliability and safety.
The motor and gearbox.
The motor used is a Flender, German manufacture. The worm gear ratio
ensures that even without the automatic break, the weight is fully
supported. The combination of gear box and break ensures precision
stopping without shaking the lamps.
The Fibreglass Cover
The moulded fibreglass cover provides protection of electrical and
mechanical parts and allows easy access for servicing.
The Flat Cable Collector without moving parts
The flat cable is collected in a specially designed trough and requires
no moving parts, that in time, can be the cause of problems.
Analog or Analog/Digital control
The control system may be analog only, or analog/digital where recording
of heights and control from a systems PC is desirable. Both the analog
and analog/digital control panel provides control for individual or
group Hoist selection . The analog/digital Hoist provides photocell
positioning detection that allows the recording of all levels for
control from a systems PC.
