Design and Fabrication of Three Way Tipper Mechanism

Sanitation is a hygienic means of promoting health by preventing human contact with waste. As such, safe removal and disposal of municipal solid waste within a community is critical in the environmental sanitation. A number of small waste collection trucks such as tricycles are in use in Ghana and other developing countries. This paper presents a design of lift-tipping mechanism for small solid waste collection trucks that enhances the safety of the waste collection component of the sanitation management. A five bar mechanism is developed with one degree of freedom. The prototype of the system built is such that for manual operation system, reverse paddling of the tricycle cycling paddle is employed in lifting and tipping. The test of the prototype result shows the torque requirement of the system ranges between 16.0 Nm and 25.0 Nm with a maximum load of 50.0 kg. A height of 1.15 m and tilt angle of 38o were obtained.

Modern 3 ways dropping dumper’ has been conceived by observing the difficulty in unloading the materials. The survey in this regards in several automobile garages, revealed the facts that mostly some difficult methods were adopted in unloading the materials from the trailer. This paper has mainly focused on above difficulty. Hence a prototype of suitable arrangement has been designed. The vehicles can be unloaded from the trailer in three axes without application of any impact force. The Direction control valve which activates the ram of the hydraulic cylinder which lifting the trailer cabin in require side. Further modifications and working limitations will put this work in the main league of use. This concept saves time & energy which leads to efficient working.

In recent years, the transport of large packages with super weight from 100 tons to several thousand tons is no longer a difficult problem due to the continuous development of technology. Experienced transport companies, specializing in transporting heavy goods in Vietnam, have invested in very modern equipment and machinery such as self-propelled trailers of Cometto (Italy) in order to transport safely mentioned parcels of great economic value arrive at the requested location. This trailer can be self-propelled, does not need to use a tractor, and only needs to use a remote-control handheld device. Moreover, the trailer gear shaft can rotate 360 degrees. In particular, the hydraulic system supports trailers operating with high accuracy and absolute safety including functions such as 360-degree rotation, lifting, transmission, braking, etc. In order to improve the performance of trailers when actually used in large projects, an important detail in the trailer's hydraulic system has been inserted a throttle valve with to increase the safety of the hydraulic pump and the entire system as well as the safety of the goods that trailers are transporting. The trailer system has transported the rig with a capacity of up to 3,200 tons in Vietnam, the shipment of 15,000 tons in the world and beyond in the future.

In the field of agriculture numerous equipments are used for various purposes. These attachments like plough, harrow, chisel plough, cultipacker, etc are mounted on the operating machine through an attachment which is then lifted as per requirement with the help of a hydraulic mechanism. No matter how efficient a mechanism might be, cost has always been and will be an important factor to decide which lifting mechanism to opt for. Hydraulic mechanism being costly, this newly designed mechanism is one of the cheapest amongst all others in the market. The main objective of the design has been coping for the high cost and bulky nature of hydraulic mechanisms to meet the attachment lifting requirements of the hand operated light weight machinery. Relative sliding motion of wedges is used for lifting of load. The wedges are actuated by a power screw. Our mechanism is designed by keeping in mind the light weight attachments like plough, supreme, ultimus, etc of a power tiller. Though it can be used in agricultural machines involving lifting of various attachments with necessary changes in dimensions of our prescribed design. The same mechanism can be used for lifting action of other heavy weight attachments of heavy duty machines. One of the primary objective of the design has been to substantially reduce the cost and size of the existing mechanism. Box dimension of our design is comparatively much less than other designs available in the market. This reduction in cost makes the mechanism affordable for farmers of every class. For commercialization other electronic actuating mechanisms can be used with the basic design structure remaining the same. It was observed that of all components bell crank is the most critical component, which was successfully analyzed for the required load.

Now a days with the increasing levels of technology, the efforts being put to produce any kind of work has been continuously decreasing. The efforts required in achieving the desired output can be effectively and economically be decreased by the implementation of better designs. These Power screws are used to converting rotary motion into translatory motion. A screw jack is an example of a power screw in which a small force applied in a horizontal plane is used to raise or lower a large load. The principle on which it works is similar to that of an inclined plane. The mechanical advantage of a screw jack is the ratio of the load applied to the effort applied. The screw jack is operated by turning a lead screw. The height of the jack is adjusted by moving a lead screw and this adjustment can be done either manually or by integrating an electric motor. In present days the two wheeler mechanic are not using lifting platform due to its heavy cost and their maintenance. Because of continuously bending of mechanic body during the repair and maintenance of two wheeler there are many health related problems are arising, also more stress and efforts are required. Limiting Deflection in Scissor Lift: Selecting lift with design capacity greater than required for the application; most scissor lift design for duty at higher capacities will experience less stress in all structural components as well as lower system pressures, at lower, working capacities. Reduced stresses and pressure always result in reduced deflection. Avoid transfer of load within the first 20% of lift travel: To minimize stress and deflection, at transfer elevations, it is critical to design the conveyor or transfer system to ensure that these elevations are above the scissor lift's " critical zone " of the first 20%of the lift available travel. Transfer load over fixed end of the lift platform: First if possible, load should not be transfer over the sides of a raised scissor lift is much more difficult to control deflection when the load is not shared equally between the two scissor legs pairs. Available Scissor Lift: 1) Hydraulic lifting platform. 2) Electric lifting platform.

There is a rapid development in the advancement of foundation these days, yet the Conventional unloaders are utilized to dump the materials like sand, rock, lattice and so forth on building locales. In regular unloader, water powered framework is utilized to push the unloader and dump the material just in back side of the vehicle. According to our study, numerous individuals think that its badly designed in regards to the dumping of vehicle. In regular day to day existence ordinary unloader isn't reasonable to dump the material in smaller spaces. Likewise vehicle can't get adequate turning sweep at little roads .The way toward emptying the unloader turns out to be more basic, impeding and tedious. To manage the issue of turning vehicle and furthermore dumping of a vehicle, a system could be utilized which will figure out how to dump the material three distinctive way.
