Passenger Control Pendant
The pendant is connected to the winch controls on an intrinsically
safe circuit through a multi-conductor (electric line) lifting wire,
through slip rings to the winch control box.
Oil-field Proven Technology
The SafeRider operates in a similar manner and using similar equipment
to a Sub-sea TV camera or ROV unit. This technology and equipment
is oil-field proven.
Simple Control Mechanism
The control assembly is made without the use of PLC hardware and
features simple logic, allowing for easy rig maintenance.
Soft Start and Stop
The SafeRider includes a variable speed drive, pneumatic soft start
or electro-hydraulic proportioning valve to ensure the rider experiences
a smooth start and stop, lessening the risk of back or muscular
injuries.
Lockout and Tagout Friendly
The emergency stop and local, remote, off switches both feature
lockout hardware that eases safe maintenance practices.
Flashing Beacon and Signaling Bell
These optional features add an additional layer of safety, The beacon
indicates to the drill floor that personnel are working overhead and
that the area is hazardous. The bell allows the passenger to signal
the winch operator. |

Local Push to Operate Button
To prevent unauthorized single person use of the man-rider, a push
to operate button has been incorporated on the local console. This
must be pressed periodically for the remote functions to operate.
Dual Redundant (Fail-safe) Braking
The winch features a fail-safe operational brake attached to the
motor and a manual parking brake. Each brake is rated at 180% of
the SWL capacity of the winch.
Type Approval
Type approval is a voluntary and rigorous design and manufacture
review by an independent competent body, such as the American Bureau
of Shipping (ABS).
Key Switch Emergency Stop Over-ride
In the event that the passenger has operated their emergency stop
and subsequently is unable to disable it (through incapacitation)
the local winch operator can over ride the emergency stop with a
key switch.
Local Control
If the passenger is busy and cannot control the winch by hand,
the local operator can control the winch under their instruction.
Cost
The SafeRider is comparatively and fairly priced with standard man-riders,
considering the additional control system. Given the cost of serious
injuries, the inexpensive Saferider pays for itself many times over.
