Abstract/ Executive Summary:

A lifter is designed and fabricated for the purpose of lifting materials like sack, basket, crate and carton from ground to truck for loading purpose and vice versa. It is a simple mechanical device used to raise element or object from ground level to a certain height to perform a specific work with maximum load and minimum efforts. Conventionally lifter is used for lifting loading and unloading agricultural products such as fertilizer, rice, wheat, vegetables, and rice husks and non-agricultural products such as cement, coal, gravels, etc. Considering the circumstances of safe work environment of the laborer in transportation activities, low cost mechanical lifting equipment was developed for reducing the drudgery of the laborer and safe handling of agricultural products. Information collection and fabrication of lifter were completed. Mechanical lifter was designed by coupling principles of hydraulic power and mechanical power of electric motor. There is a horizontal base frame which is supported by 4 number of rubber tyre wheels. It is a walking type lifting device. The main component are (i) main frame (ii) stacker with fork (iii) hydraulic pump (iv) electric motor (v) counterbalance assembly (vi) push/pull handle with accessories. Primary target of weight (100 kg) and lifting height from 3 to 2.5 m; i.e., up to the floor of transportation truck. Dimension of lifter is 6.096?0.854 m. The experiment will be continued for next year.

End Date:

Program Area: Farm Mechanization

Commodity: Farm machineries

Objectives:

To develop a low cost mechanical lifter for safe handling of agricultural products especially for loading unloading in transportation vehicles
To test the performance of the lifter for reducing the drudgery of labourers
To disseminate the lifter in the sector of agricultural products storage and distribution activities

Methodology:

Project sites: Building upon past work, we propose to fabricate the mechanical lifter at Farm Machinery & Postharvest Process Engineering Division, BARI, Joydebpur, Gazipur. Fabrication of mechanical lifter:: Mechanical lifter was to be designed by coupling principles of hydraulic power and mechanical power of electric motor. There was a horizontal base frame which is supported by 4 number of rubber tyre wheels. It is a walking type lifting device. The main component are (i) main frame (ii) stacker with fork (iii) hydraulic pump (iv) electric motor (v) counterbalance assembly (vi) push/pull handle with accessories. Primary target of weight (100 kg) and lifting height 2.14 m; i.e., up to the floor of transportation truck. Materials collection, Fabrication, testing of mechanical lifter: The materials of mechanical lifter were collected from local market. The lifter would be fabricated at FMP Engineering Division, BARI, Gazipur. The lifter would be tested for loading and unloading of transportation truck with wheat seed, fertilizer bag, and vegetables. Data collection: (i) Weight lifting capacity (kg), (ii) height of lifting (cm), (iii) time of loading in a transportation truck (min.), (iv) unloading a truck (min.), (v) number of labour involvement both lifter and manual method, (vi) cost of loading & unloading with both lifter and manual method. Stakeholders Local manufacturers was involved in the mechanization works for skill development. The main stakeholders were local seed dealer, fertilizer dealer, owner of transportation agency, owner of rice mill, who are frequently associated with load unload of agricultural inputs and products in the transportation vehicle.
