USGS Stand-up Cable Car -
Model 4500
The USGS has designed two different style cable cars for stream
gaging and water sampling for sediment or chemical quality. A
cableway stretched across a river provides a convenient way for
making discharge measurements or sampling. The cable car is a
very economical solution for obtaining measurements at a
specific river location and in remote locations. Because the
same sounding reels used for bridge or boat measurements are
used, this eliminates the need for double drum reels and allows
the hydrographer more control of the discharge measurement than
operating remotely from the river bank. The stand-up cable car
allows a person to stand up while taking discharge measurements
or water samples. It is especially desirable when obtaining
water quality samples as it allows the field man more mobility.
It is made from aluminum stock and has a solid aluminum plate
diamond-tread floor. The sheaves are a bronze alloy and are
designed to fit on cable up to 1.5 inches (3.8 cm) in diameter.
The car is pulled along the cable by a handheld puller, and has
a built-in follower brake assembly to position the car anywhere
along the cableway. The brake can be activated from any position
in the car. A rack for sediment or water quality sampling
bottles is attached to the side of the car. A protractor is
attached to measure the sounding line angle. The reel mount is
drilled to fit the A-Pack, A-55, B-56 and E-53 reels. The cable
car width is 27 inches (68 cm), the length is 52 inches (132
cm), and the distance from the cable to the floor is 73 inches
(185 cm).

USGS Sit-Down Cable Car - Model 4550
 The sit-down cable car is made of
aluminum stock, including a solid two-piece foot rest. The operation
is identical to the stand-up cable car's, and also is designed to fit
on cable up to 1.5 inches (3.8 cm) in diameter. The reel mount is
drilled to fit A-Pack, A-55, and B-56 reels. The E-53 Reel and heavier
weights should be used with the model 4500 Stand-Up Cable Car. The car
width is 21 inches (53 cm), its length is 60 inches (152 cm), and its
distance from cable to floor is 55 inches (139 cm).

USGS Sand Point Cable Car Brake
The Sand Point Brake can be added to any
USGS Stand-up or Sit- down cable car and attaches to the top rail. A
hand wheel is used to tighten two brake pads which clamp down on the
main cable for improved braking and control as well as holding it
securely in position.

USGS Nisqually Cable Car Brake
The Nisqually Brake was designed to easily
attach to any USGS cable car. It is a simple yet very effective brake
that has a thumb screw control to change brake tension. The brake is
also used to securely clamp the cable car in position.

USGS Cable Car Pullers
 A cable car puller is
used to move a cable car along a cableway. The puller is mounted on
the cable between the two sheaves supporting the cable car. The puller
is fitted to the cable with the handle pointing in the direction the
car is to be moved and the free end of the brake belting must be
toward the upgrade side. These are available in two sizes for up to 1"
cable and up to 1 3/8" cable.

 Follower
Brake-Type Cable Car Puller
The Follower Brake-Type Cable Car
Puller provides a method of propelling the cable car from one point to
another along the cableway. The roller rides atop the cable and the
brake shoe rides below it. By pinching the cable between the puller's
roller and brake shoe, and applying manual pressure, the car may be
moved along the cable. This cable car puller should not be used to
hold the cable car in position.

The Cable Car Hook is
used to secure the cable car, when not in use, to its parking place on
the cable. The hook is attached to the cable by two "U" bolts
(included) and a Cable Clamp (not included). A 36-inch chain securing
the cable car is included with the hook. Any standard padlock (not
included) may be used to secure the chain to the cable car.

Shield for Cobralink Lock
The shield is designed to provide
protection from vandalism. The two-part shield consists of a body
and cover plate. The Cobralink lock is inserted through holes in
the sides of the shield body with the lock inside the shield. The
cover plate is then positioned through the slot in the side of the
shield body and the hole in the cover aligned with the hole in the
body tab and locked with any standard padlock (not included).
