selection operation and maintainance of mobile cranes ( for education purpose...swaroop k s
A mobile cranes are machine that could lift, pull, tug, carry, and do many such things that are done on a large scale. It is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck- type carriers or as self-propelled models. They are commonly used in the construction industry and in the manufacturing of heavy equipment.
Rough Terrain Crane A crane that is mounted on an undercarriage with four rubber tires, designed for operations off road. The outriggers extend vertically and horizontally to level and stabilize the crane when hoisting. These types of cranes are single engine machines where the same engine is used for powering the undercarriage as it is for powering the crane. In these types of cranes, the engine is normally mounted in the undercarriage rather than in the upper portion.
These cranes can go from the paved highway to the rocky landscape of a job site. They can reach speeds necessary to travel on public highways, yet have the power necessary to handle a variety of construction tasks. This mainstay of the heavy equipment industry main asset is its versatility. All terrain cranes can handle up to 1,300 short tons of weight

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

2. CRANE
• A crane is a type of machine, generally equipped with a hoist rope, wire
ropes or chains, and sheaves, that can be used both to lift and lower materials and
to move them horizontally.
• It is mainly used for lifting heavy things and transporting them to other places.
• The device uses one or more simple machines to create mechanical advantage and
thus move loads beyond the normal capability of a human.
• Cranes are commonly employed in the transport industry for the loading and
unloading of freight, in the construction industry for the movement of materials,
and in the manufacturing industry for the assembling of heavy equipment.

4. CRAWLER MOUNTED CRANE-INTRODUCTION
. The crawler crane is basically a tracked vehicle that has a crane mechanism
attached to it.
2. This crane has the capability to work on every type of ground surface, even on
the softest grounds, thanks to its specially designed track properties. The metal
tracks make the crawler crane very stable on the ground and also provide increased
maneuverability on the ground.
3. The lifting capacity of the crawler crane ranges from 30 to 3000 tons depending
on the model.
6. COMPONENTS
1. CRANE: consists of a rotating structure for lifting and lowering horizontally on crawler treads
2. HOIST: used to lift and lower load
3. BOOM: an inclined spar, strut, or other long member supporting the hoisting tackle
4. JIB: extension attached to the boom point to provide added boom length for lifting specified
loads
5. COUNTER WEIGHT: weights used for balancing loads and the weight of the crane in providing
stability
8. 1. All crawler cranes consist of several parts. The propulsion system and the tracks
are the main parts of the crane.
2. A long boom is attached to the cabin and can be raised high above the control
cabin. Cables move through the boom and a hook is attached at the end of the boom
for catching, lifting and moving various kinds of items and loads from one place to
another.
3. Some crawler crane models come with additional part known as a jib which is
attached at the end of the boom. The jib allows the crawler crane to move items
even further from its position on the ground. The crawler crane moves like a crawler
tractor, but because of its weight it moves very slowly on the ground.
4.One main feature which allows the crawler crane to lift and move heavy loads
without losing control is the counterweight. The counterweight are usually placed at
the back of the crane and can weight up to several tons. The crawler crane is
versatile machine , capable of performing and completing various lifting tasks on all
types of groung surfaces and weather conditions.
9. ADVANTAGES AND DISADVANTAGES
The MAIN ADVANTAGE of the crawler crane is the ability to move and lift items
and other heavy loads around the construction site very easily. In addition,
the tracks of the crawler crane provide support and increased stability.
• The BIGGEST DISADVANTAGE of the crawler crane is the big size and weight.
The crawler crane is not transported fully assembled. They are just too big
for the roads. That's why they are delivered in manageable pieces and
assemble on site. This can be a project on its own and will involve a team of
professional heavy lifting technicians such as riggers and operators. The
configuration of the crane is predetermined in advance by the lift engineer
based on the customer's project requirement.

14. MAJOR CAUSES OF CRANE ACCIDENTS
the major causes or crane accidents to include :
1. Crane buckling or collapsing: All cranes have weight limits to ensure that
the crane will not tip over. To counter balance the weight, cranes use
counterweight and out-rigging systems. If the maximum weight is exceeded,
the crane will be in danger of either buckling or the boom may collapse.
2. Improper crane assembly: One of the biggest reasons that a boom collapses
is improper assembly. Specifically if the crane does not have the proper
blocking (wood or metal supports) to stabilize the load, the unbalanced load
will move and may lead to the crane collapsing.
3. Improper employee training: Operators who do not have the proper
training in crane operation and safety procedures may lead to crane
accidents.
15. 4.Mechanical failures: Routine crane maintenance should be followed to prevent
accidents due to mechanical failure. Crane components with excessive wear
should be repaired and replaced right away.
5. Contact with overhead power lines: Electrocution from contact with overhead
power lines is leading cause of crane related accidents. Both the crane operator
and workers in the crane basket should be aware of the placement of power lines
surrounding the worksite. Before work commences the current to active power
lines should be shut off to prevent electrocution from accidental contact with
live wires.
6. Flawed or infrequent inspections: Timely, consistent inspections by
experienced and well trained inspectors can wholly prevent tragic accidents.
16. PLANNING BEFORE START-UP
1.Level the crane and ensure support surface is firm and able to support the load.
2.Know the basic crane capacities , limitations, and job site restrictions ,such as the location of
power lines ,unstable soil or high winds.
3.Contact power line owners and determine precautions . Know the location and voltage of
overhead power lines.
4.At the beginning ,walk-around your crane checking for mechanical , electrical , structural , and
hydraulic issues (MESH).
5.Make other personnel aware of hoisting activities.
6.Barricade areas within swing radius.
7.Ensure proper maintenance and inspections.
8.Determine safe areas to store materials and place machinery.
17. APPLICATIONS
1.Used in lifting operations on different ground surfaces, including soft ground .
2. Used in demolition.
3. Used in bridge/road construction.
4.Used in Cargo loading.
5.Used in removal of debris.
