SOVIET TRUCK-MOUNTED CRANE
The crane equipment, type LAZ-690, is mounted on motor vehicles of types
ZIS-150, ZIL-150, and ZIL-164, made in the same plant. The ZIS-150 is an
older model, the ZIL-164 a more recent model.
The crane is attached to the frame of the truck by means of clamps.
The only other addition is a gearbox for power take-off. This gearbox
is placed behind the driver's cab, under the gas tank. The drive shafts
are of a special type, being mounted .n bearings in the power take-off
gearbox.
The truck weighs 4 tons, the crane 3 tons, total 7 tons.
According to the manufacturer's description, the crane has a lifting
capacity of 3 tons, but it is capable of lifting 4 tons. With an arm exten-
sion (the horizontal distance between the crane hook and the central axis) of
2.5 meters, the capacity is 3 tons, and with an extension of 5.5 meters, 1 ton.
These movements can be carried out simultaneously:
1. Load lifting and crane arm lifting
2. Load lowering and crane arm lowering
3. Load lifting and swing to the left
4. Load lowering and swing to the right.

Crane arm movements and crane swinging on the spot cannot be carried
out simultaneously (sic).
Loading speed is very high
300-400
cubic meters of logs (log length 5 -6.5 meters) onto trucks in eight hours.
The loading operations carried out in this period included hooking the loads
together, unhooking the loads, distributing the logs on the truck, and as-
sembling the logs for loading. In working with prepared loads (with the crane
doing all the work), the loading speed might be two or three times as great.
The road speed of the crane truck is equal to that of a flat bed truck of the
same make.
A more powerful version of the crane, the AK-5, has a lifting capacity
of 5 tons. Its outrigger feet are longer and some of the crane elements are
reinforced.

Engaging the Crane for Operation
To put the crane into operation, the lever is moved in the direction op-
posite to the forward direction of the truck, and the truck gear shift lever
(8) is placed in position I. II, or III, depending upon the desired working
speed. The lever (3) disengages the truck drive shaft (5) and at the same
time engages the crane drive shaft (I+). This engagement and disengagement takes
place in the lower part of the crane power take-off box (2).

disengagement of the crane drive shaft (1.) takes place in the lower part of
the gear box (2) [which is] lined up with drive shaft (5) and intermediate drive
shaft (9). Gear box (2) also has, above this coupling, two more shafts, lying one
above the other and having gears.
Crane Operation
A lever in the crane operator's cab controls the shaft (10). Gears
(a and b) rotate freely on bushings on shaft (11), both gears being in con-
stant mesh with conical gear (d). Cylindrical gear (g) and conical gear (d)
are fixed to shaft (13). Clutch sleeve (c) is fixed to a spline on shaft (11)
and can be moved up or down by means of fork and shaft (10). When the clutch
sleeve is moved upward, the teeth of sleeve (c) engage the teeth of gear (a), and
in
gear (a) rotates/the same direction as shaft (il), transmitting its rotationary
movement to gear (d). Meanwhile, the lower conical gear (b) is rotated by
gear (d) in the direction opposite to that of the upper gear (a) on the op-
posite side of shaft (11).
Downward movement of sleeve (c) frees upper gear (a) and the teeth of
sleeve (c) engage the teeth of lower gear (b), causing the lower gear to
rotate in the same direction as the shaft, transmitting the rotationary move-
ment to gear (d). Upper gear (a) will now move in the direction opposite to
that of the shaft. Since gear (d) is driven by upper gear (a), gear (d) move in
one direction, but if it is driven by lower gear (b), gear (d) moves in the
opposite direction together with gear (g). This is the means of rotating the
crane to the left or rjght, lifting and lowering the load, and lowering and
raising the crane arm.

There are three brackets (3) holding rollers (4). Two rollers are
fastened to each brakcet. The control wires pass through in pipes which
do not rotate with the crane. At their upper end there is a fastening provided
with rollers and a track corresponding to the track (8) and rollers (4) on which
swing the crane rotates. The teeth of the worm gears of the winch and the
crane rotation drive are not straight but curved, and all worm gear wheels
and worm gears in the winch, respectively, are similar, while the worm gears
of the rotation drive are longer and of different shape, the worm gear wheel
ti
also being of different shape. The wich worm gear wheels are of cast iron
and can be removed from the winch drum for replacement when worn out.

The Worm Gear and the Conical Disk of the Crane Turning Gear Box
The upper conical disk (4+) is splined to the axle, while the worm
gear wheel (5) moves freely. When by means of the spring (3) the upper
conical disk is pressed into the conical recess in the gear wheel the axle
is engaged and begins to turn. The disks are not exactly conical in form,
but womewhat elliptical to provide a better connection and smoother operation
without jerks or shocks. A jerk or shock results in the conical disk being
lifted by the pressure of the recess and dropping back into the elliptical
recess after one turn under the pressure of the spring.

Conical gear (D) and cylindrical gears 1 and 2 are affixed'to
a~ axle (g). Gear wheels 3, 4, and 5 ride on bushings and are in constant
mesh with gears l and 2. Axles e and b/h are fluted, with sleeves A
and B sliding in the flutings. When lever k moves sleeve B to gear
wheel 3, engaging teeth m, axle a will rotate. In turn, the axle will
transmit the rotationary movement to the loading winch. The same thing
takes place with axle b/h. The difference is that sleeve A has teeth
at both ends, one end engaging the crane arm winch, the other end the
crane turning transmission. Turns to the left or right are engaged in
the turning transmission by means of fork p and the toothed sleeve (c
in Appendix 2) found under the conical gear wheel (7 in Appendix 2).
Axle h is in two sections. When sleeve A is meshed with gear 4, the part
of the axle which extends to the crane turning transmission does not
rotate. When sleeve A engaged gear 5, thepart of the axle which extends to
the crane arm winch does not rotate. One of the axle sections rests in
two bearings, one end of the other section resting in a bearing and the
other end extending into one end of the other axle section.
