Location and Description of Major Components.
(1)
Crane (1, Figure 1-5). Provides backup well servicing capability, as well as tool and casing handling
support. Located at the rear center of the waterbed, the crane turret and boom assembly rotate
continuously in any direction. Crane operation is by remote pendant control stored in the base of the
crane. Hydraulic and electrical power is controlled from a panel inside the truck cab.
(2)
Welder and Generator (2, Figure 1-5). Self-contained unit mounted at the top, front center of the
waterbed. The unit is used as an alternating current (ac) or direct current (dc) welder and as a power plant
for supplying auxiliary power.
(3)
Welder Engine (3, Figure 1-5). Provides power for welder/generator unit. It is an air-cooled, single
cylinder, electrically started 14-horsepower diesel engine.
(4)
Fuel Transfer System (4, Figure 1-5). Consists of an auxiliary fuel tank, fuel transfer pump, hose, and fuel
nozzle. Electrical power to operate the pump is controlled from inside the truck cab. Fuel flow is
controlled at the nozzle.
(5)
Water Heater (5, Figure 1-5). Consists of integrated open-loop water heating manifold. Contains liquid
propane (LP) gas heating torch, hose, pre-set regulator, manifold mounting bracket, and LP tank. Manifold
also provides in-transit storage for water pump hoses.
(6)
Waterbed (6, Figure 1-5). Provides water storage for rotary well drilling operations. Water level is
indicated by magnetically operated water level gauge. Filling and discharging operations are by rotary
reversible water pump.
(7)
Water Pump (7, Figure 1-5). Provides ability to move water into or out of the waterbed, or from one
external water source to another without going through the waterbed. The pump is a hydraulically driven
unit, mounted in the rear curbside tool box. Hydraulic power is controlled from inside the truck cab. Pump
is engaged and disengaged by an air-shift control located at the pump.
(8)
Hydraulic Reservoir (8, Figure 1-5). Holds fluid that hydraulically drives either the water pump or the front
winch. Air-shifted controls operate the tank-mounted valves that direct the flow of fluid.
(9)
Winch (9, Figure 1-5). Hydraulically driven, 20, 000-pound capacity unit mounted on front of truck.
Operated from inside the truck cab by an airshift control. Used for pulling drilling rig or rig tender.
(10)
Night Liqhtinq (10, Figure 1-5). Consists of two floodlights mounted on vertical cabinets behind the truck
cab. Electrical power ON/OFF switches are inside the truck cab.
