Description
Technical field
The invention belongs to engineering transportation field, and in particular to a kind of multifunctional engineering is with pulling/cart.
Background technology
The relatively small specialized engineering of many contract amounts, such as water process, desulphurization and denitration, dedusting, recirculated water, engineering
In have many weights of equipment between 100-500kg, it is necessary to often unload from truck, situation about being had bad luck into construction site.
The equipment and component of super more 100kg is run into, generally requires increase manpower lift, more than 200kg, crane, fork truck or other are suitable
The use of engineering truck is with regard to inevitable, and domestic project vehicle toll majority is according to half of machine-team starting or by short-term at present
Access times calculate, and price is very considerable.Nowadays it is the epoch of a globalization, the part of appliance of an engineering is sent out from all parts of the country
Come, even from foreign countries, often, haul number of the equipment from stockyard to building site is also more for unloading, using equipment and manually
Expense goes up at double, and the control to cost of transportation inside and outside engineering brings very big difficulty.
At present, 1.5 meters to 2 meters long cart majorities are transport light components or equipment, do not lift function.On the market
Small-sized cantilever trolley of the part with Lifting Capacity takes up an area big, it is necessary to by means of electric power, connects electric inconvenience, and do not possess unloading and
Transportation function.Some another beam cranes, is equally by electric power, takes up an area bigger, without transport capacity.
Usually it can just have time and shift since it is desired that wait crane to hang last consignment of cargo again when place goods inside is had bad luck
Place hoisting, that has bad luck is inefficient.
One kind is sought after at present with lifting, unloading function and uses manpower few, without the help of electric power, while can also be competent at
The multi-functional push/pull car of weight ability is hauled, there is no associated description in the prior art.
The content of the invention
Technical problem solved by the invention is that providing one kind carries lifting, turn-round function and use manpower few,
Without the help of electric power, while haul the multi-functional of weight ability can also be competent at and pull/cart.
The technical solution for realizing the object of the invention is：A kind of multifunctional engineering is with pulling/cart, including pulls/push away
