Description

A kind of portable fork truck
Technical field
The utility model belongs to fork truck technical field, and in particular to a kind of portable fork truck.
Background technique
With the development of logistics, a kind of fork truck extensive, mobility strong material handling and loading equipment as function is obtained It is more and more widely used.Forklift Industry also enters one than faster developing period, the research of fork truck and design level It is continuously improved.But fork truck own wt outstanding problem, malfunction, it is horizontal further to have become fork truck design and producing The bottleneck of raising.The practicability of fork truck and operability requirement are increasingly stringenter both at home and abroad at present, how to solve flexibility and matter Amount problem becomes the key factor that Forklift Industry exists and develops.The especially development of Express Logistics industry in recent years, people couple The requirement of working efficiency is higher.
Type hand forklift with its light and flexible, it is easy to operate, work needed for space it is small the advantages that obtain warehouse, logistics, The extensive utilization of port and pier, factory and enterprise.Industrial transportation vehicle product will enter the places such as workshop, storehouse, supermarket, not only want It asks that vehicle is pollution-free, low noise, while the technical requirements such as energy conservation and environmental protection, portable construction also is proposed to vehicle.These requirements Only small-sized carrying vehicle is easy to accomplish.And structure is complicated for current hand-hydraulic forklift, weight is big and can only be by cargo Eminence is moved to from lower, cargo cannot be followed to reach eminence, there are limitations.
Aiming at the problem that hand-hydraulic forklift of the prior art can only move cargo to eminence from lower, Chinese patent (publication number:106915715A) disclose a kind of portable forklift that can be climbed to a higher point.Climbing to a higher point for the patent disclosure is portable Lifting drive mechanism is provided in forklift rack, lifting drive mechanism is connected with pallet fork, and mechanism makes pallet fork by lifting drive Opposite rack upper and lower displacement, frame bottom are equipped with stabilizer blade, and frame bottom and/or feet bottom are connected with wheel, stabilizer blade and rack It can only be translated up in the side parallel with pallet fork.The patent can only be translated up by stabilizer blade with rack in the side parallel with pallet fork Flexible connection design, although cargo can only be moved to eminence from lower by solving the hydraulic forklift of common manual, cannot follow Cargo reaches the technical issues of eminence, but forklift in the prior art still has following deficiency:
1, lifting drive mechanism is designed using pulley, chain structure, and its structure is complicated, and significantly increases hand fork lifter Own wt.
2, it provides the hydraulic system of power source and pallet fork is structure as a whole design, the self weight of increase fork truck upper fork, so that The loading capacity of pallet fork declines, while during forklift fortune, carrying moving up and down together for hydraulic system, so that fork truck consumes energy Increase.
3, pallet fork it is Chong Die with stabilizer blade so that pallet fork can not ground proximity, to can not with some relatively low pallets or cargo It carries out forking operation.
Utility model content
In order to solve the above problems existing in the present technology, the utility model provides a kind of portable fork truck.This is practical The novel improvement by forklift door frame realizes the lifting that hydraulic cylinder connection replaces chain in the prior art and pulley to form System, effectively reduces the quality of fork truck, and the one end in outer mast closely face is arranged in cabinet by the utility model, is subtracted The carrying weight of fork truck is effectively promoted, so that fork truck is more energy-saving and environmentally friendly in the weight for having lacked inner upright mounting.The utility model is also Vehicle body hanger and prong are improved, so that prong is can be with ground proximity and Chong Die with vehicle body hanger.
