It is powered by an engine and safe to operate and inexpensive to maintain. The wheel drum of the device is designed for move along the trunk of the tree without any damage to the trunk of the tree.

Description
This invention concerns a tree climbing
device for climbing up trees which have a single stem,
such as palm trees or coconut trees.
The majority of coconuts are harvested
by climbing the tree and cutting the nuts down by
hand. This process may seem simple, however it is
quite dangerous. In Thailand and Malaysia monkeys are
trained to gather nuts from the sky-rise trees. In
other parts hydraulic platforms are used to lift
harvesters. But these steps are not proved economically
viable.
The coconut producing states are
facing an acute shortage of tree climbers. An
experienced climber takes about 4-5 minutes alone
just to climb the tree (this doesn't include
cutting the coconuts and the return trip). In
more developed areas, methods of harvest and coconut
removal involving rope-climbing gears and spiked
shoes are used, but those methods are
impractical and inefficient for use in large scale
plantation harvesting. Although there are
efforts made by many inventors, many climbing
devices that assure efficiency, but not
necessarily safety.
This invention provides a device for
climbing trees and other vertical members.
This invention describes a device
which is powered by a power source or an engine.
This invention also provides a
device which is safe to operate and inexpensive
to maintain.
This invention is also adapted to
engage a vertical member which does not have a
smooth or straight surface.
This invention describes a device
which can move along the tree without any damage
to the trunk of the tree.
This invention describes a device
which maintains engagement with the member being
climbed throughout the climbing operation.
This invention also allows a human
to climb up to the top of the tree safely, pluck
nuts or a bundle of fruits and get down safely
at a controllable speed.
This invention has considered about
the safety of climber and has taken precautions
to avoid any damages to be occurred to the climber.
This invention describes a device
which can be carried on by climbers from one
plantation to another.
The present invention relates to a
device that may replace the common technology
used today especially for palm plantations. The
device can rise to any desired height without risk
to a person or damage to the surface of the
tree. The price of the proposed device can be low
enough for the climbers to afford. The device
according to the present invention will be able
to do the work faster, cheaper and much more safely
for a much lower price.

As shown in Fig. 1 safety tree climbing
device comprising a wheel drum (1), the first frame
portion (10), the second frame portion (11), a locking
system (4) at the free end of each frame portions, a
seat (9) for the climber, a safety belt (5), a brake
paddle (3), a safety cable (6) and a power source
/engine (2).
The device may be used to climb the
tree without any damage to the trunk of the tree due
to wheel drum (1) which comprises two main wheels (15)
made of steel and a plurality of belts (16) which
combines two main wheels together. Belts may be made
of coir, rubber or leather material.
The distance between two main wheels
(15) can be decreased or increased by the horizontal
actuator (28) to position the wheel drum attached to
the trunk of the tree depending on circumference of the
tree (Fig. 16 & 17). The lateral components (29)
attached to the main wheel (15) may involve in
engaging the tree trunk tightly and securely when the
trunk is slippery.
Two wheel drums (1) can be incorporated
to the device for engaging the tree trunk tightly as
shown in Fig. if the tree trunk is slippery.
The speed control wheels (27) connected
to wheel drum (1) may be used to control the speed of
the device when climber descends the tree.
The wheel drum (1) is connected to the
engine (2) via an axle (30)which provides energy to
wheel drum (1) to move along the tree trunk.
The first frame portion (10) and the
second frame portion (11) are spaced apart from each
other and connected to the U shape bar (14) at one end
and generally take circular shape to be positioned
around the trunk of a tree.
The first frame portion (10) and the
second frame portion (11) have a locking system (4) at
the other end which allows the device to be connected/
detached to the trunk of the tree.
Each frame portion (10, 11) have two or
more adjustable wheels (08) in each side of the frame
as shown in Fig. 02. As shown in Fig. 05 these
adjustable wheels (8) can be moved along the frame portion.
As shown in Fig. 04 and 05 each
adjustable wheel (08) is connected to a wheel
adjusting unit (21) and this unit can be positioned to
attach the tree by pressing the pressurizing unit (18).
When the pressurizing unit (18) is pressed, the
adjustable wheels (08) are locked by the thread bar
(20). The pressure can be released to move the
adjustable wheels by pulling the lock release (19) and
the spring of the lock (17) will be released.
Fig. 08 and 09 describe the locking
system (04) at the free end of each frame portion. 12
A/12B and 13A/13B portions are connected to the first
frame portion (10A/10B) and the second frame portion
(11A/11B) respectively. 12A portion and 12B portion
are connected to the first frame portion (10A &
10B) by two nails 23A & 23B respectively.
12A portion may be passed through the
12B portion to connect each other and may be locked by
passing the locking nail (24) through the passages
between the 12A and 12B portions. 13A and 13B portions
may be connected and locked by the same way as
described above.
A safety cable (06) is connected to
first frame portion (10) of the device which may help
to stop the device for safety of the climber if either
the engine ceases accidentally or speed control wheel
set is not functioning properly.
The safety tree climbing device can be
used to climb trees with a single stem such as palm
trees or coconut trees or to climb any vertical
member. The device is useful to harvest fruits like
coconut, king coconut and arecanut which are grown at
the top of a tree.
