SOUNDING REELS
Sounding reels are used with Gurley
current meters to measure depth and lower the instrument from a crane
or boat. All reels can be used with either headhones or Model 1100
Digital Indicator. Please specify before ordering.

USGS BRIDGE BOARD
The bridge board was designed for use
in making discharge measurements and obtaining water quality samples
from off of bridges. It is a free-standing support, accommodating
A-Pack, A-55 or B-56 sounding reels. It comes with an adjustable foot
rest which makes it easily adaptable to bridge railings of different
heights and walkways of variable widths. The maximum sounding weight
to be used with the bridge board is 50 pounds (23 kilograms).
USGS TYPE A CRANE WITH
THREE-WHEEL TRUCK
The Type A crane is a collapsible crane
intended for measuring discharge or sediment sampling from bridges. It
attaches to either the type A three-wheel truck or the Type A
four-wheel truck. The crane is made from aluminum stock with an
aluminum outer sheave with ball bearings and a bronze inner sheave.
The crane includes a reel mount drilled to accommodate the A-55, B-56
and E-53 sounding reels. It is easily put up and folded down into and
easily carried size with no nuts and bolts to put in or remove. The
USGS 12-volt electrical power drive unit attaches to this crane with
no adaptation necessary.
A liquid-filled (colored antifreeze)
protractor, to obtain the vertical angle of the sounding line, also is
available as an accessory. The protractor measures vertical angles
from –25 degrees to +90 degrees. A USGS stream velocity correction
chart also is included with the protractor. Approximate weight of the
crane is 45 pounds (20 kilograms).
The Type A three-wheel truck, when
attached to a Type A crane, is a popular bridge measuring outfit which
is used for weights up to 100 pounds (46 kilograms). The Type A
three-wheel truck consists of a two-wheel base assembly, a third
(roadside) wheel, and all necessary chassis components. The two-wheel
subassembly can be removed with two 3/8 inch (1.0-centimeter) wing
nuts to compactly store the collapsible crane.
This unit is easier to set up, operates
in a narrower space, and is more maneuverable than the four-wheel
truck, also available for the Type A crane. When in use, the crane is
tipped up and stands on the two inside wheels while the crane rests on
the bridge railing so the boom is extended out over the river. It is,
however, less stable with heavier weights, and the boom on the crane
does not extend as far as it does on the four-wheel truck. The
approximate weight of the truck is 25 pounds (11 kilograms).
USGS TYPE A CRANE WITH A TYPE A
FOUR-WHEEL TRUCK
The Type A crane is a collapsible crane
intended for measuring discharge or sediment sampling from bridges. It
attaches to either the Type A three-wheel truck or the Type A
four-wheel truck. The crane is made from aluminum stock with an
aluminum outer sheave with ball bearings and a bronze inner sheave.
The crane includes a reel mount drilled to accommodate the A-55, B-56
and E-53 sounding reels. It is easily put up and folded down into and
easily-carried size with no nuts and bolts to put in or remove. The
USGS 12-volt electrical power drive unit attaches to this crane with
no adaptation necessary.
A liquid filled (colored antifreeze)
protractor, to obtain the vertical angle of the sounding line, also is
available as an accessory. The protractor measures vertical angles
from –25 degrees to +90 degrees. A USGS stream velocity correction
chart also is included with the protractor. Approximate weight of the
crane is 45 pounds (20 kilograms).
The Type A four-wheel truck attaches to
a Type A crane. The rear assembly is adjustable in a vertical
direction so that the platform surface will remain parallel with the
road surface when operated on curbs or sidewalks. One front and one
rear wheel swivels for steering. The handle is collapsible, folding up
underneath the truck for ease of transportation and storage.
Up to four 60-pound (27 kilogram)
counterweights may be used as ballast when using heavy sounding
weights or samplers. The 150-pound (68-kilogram) sounding weight is
the maximum to be used with this assembly.
The Type A four-wheel truck is made
from aluminum stock with galvanized steel shafts and solid hard-rubber
tires. The width is 31 inches (91.4 centimeters). The truck weights
approximately 85 pounds (39 kilograms).
