Vehicle-mounted lifting device

Abstract

The invention discloses a vehicle-mounted lifting device, comprising a base, a support, a lifting plate, a hydraulic device and two chains, wherein the vehicle-mounted lifting device is placed on the ground surface and the lifting plate is driven by the hydraulic device to rise. At the beginning of working, weights such as bagged rice, bagged soybean or cement and the like to be lifted can be put on the lifting plate, and then lifted by the vehicle-mounted lifting device so that the height of the weights exceeds the goods shelf of an automobile. The exceeding height can be determined according to the height of the unloading personnel on the goods shelf of the automobile. The vehicle-mounted lifting device solves and reduces the strength of tens of thousands of loaders used in loading and unloading goods; and the loading / unloading efficiency is improved and the labor of the loaders is saved; and besides, a hydraulic cylinder is employed for driving, thereby being quite safe and reliable.

Description

technical field [0001] The invention relates to the field of lifting machinery for heavy objects, in particular to a vehicle-mounted lifting device. Background technique [0002] In our country, except for large-scale farms that can use mechanization, most people in the country still use their shoulders to carry the harvested grain into their yards, and then when selling grain, they need to put pots in their pockets, and then Carried on the transport vehicle on the shoulder. Because the container of the vehicle has a certain height from the ground, it is common practice to build an inclined bridge between the vehicle and the ground, and the stevedores will carry the grain onto the vehicle through the inclined bridge. However, this kind of work consumes great physical strength of the stevedores, and is inefficient, and the labor load of the stevedores is very large. [0003] There are also some lifting devices at present, but the current lifting devices are usually driven b...

AI Technical Summary

Problems solved by technology

[0004] 1. The motor drive consumes a lot of electric energy. For the grain dealers who go to the countryside to buy grain, they need to connect electricity from the farmer's home, which is very inconvenient.

[0005] 2. Because the weight of the heavy object lifted by the lifting device will change, the current and voltage of the motor are usually unstable, which will easily cause damage to the circuit in the farmer's home
