Safety Characteristics of the Skylock (over speed protection)
•
The Over speed protection device (
Skylock)
will allow the wire rope to pass at a safe speed, activation of this device is referred
to as “tripping” or “engaging”. The device
is utilised on all Adfinis False Car
’s with the following purpose
: -
•
Failure of main winch rope
•
Mechanical failure of the hoist creating an over-speed
•
The Sky Lock is a fall arrest device and is engaged mechanically or automatically at a factory preset speed in excess of 25m/min.
•
Skylock Operation
–
can trip manually by rotating the manual lever anti clockwise. The operator may do this if they wish to remove the winch or change winch
ropes.
•
Before resetting the Skylock live load must be transferred to the main suspension primary rope by driving the hoist up approximately 50mm.
•
Reset by rotating the reset lever clockwise which allows the Skylock to be released from the rope.
•
To test pull the rope quickly from above and it should engage instantly.

Brake Operation of a Rail Guided False Car
•
The brakes are engaged manually by releasing the handle on the spring device or automatically by the release of tension on the spring in the device if the frame ever
becomes detached from the winch.
•
Brake Operation
–
The brake system functions through the movement of a hardened knurled roller (gripper) forced against the Lift Rail (compression)
•
When the brake handle is moved to the UP position the brake arm releases the knurled grippers (away from the rail), against the tension of the springs. This moves
the gripper down and away from the rail to allow movement of the false car.
•
When the handle is moved to the down position the tension of the springs pulls the roller up into the narrow section of the slot causing the gripper to engage and
prevent downward movement.
•
Drive the false car up to disengage the grippers before moving the handle to the up position to release brakes. If the brake handle is forced while the grippers are
engaged the handle may malfunction.
•
Do not tie off or prevent brake system from operating unless an additional safety device is fitted e.g. second Skylock on independent rope
•
When at working position engage brakes and Skylock if required.
•
Do not drive false car out of rails beyond the brake block.
•
Do not exceed 250 kg on platform (Approximately 2 technicians & tools). Not to be used to transport people other than those working in the shaft or materials other
than tools i.e. not for trimmer beams or other heavy objects.
6.
Electrical Safety
•
Each False Car is fitted with a Work Light and a Non-Maintained Emergency Light. In case of power failure inside the lift shaft, the emergency light will become
illuminated and stay illuminated for approx 120 minutes.
•
Power to all electrical items is supplied by the Power Control Unit, containing a RCD. The RCD should be manually tripped every morning before starting work.
•
When tripping the RCD the emergency light should become illuminated.
