Abstract

The utility model relates to a hand powered lifter which is mainly used for lifting the heavy objects to a high position and is suitable for lifting building materials on building sites or lifting yachts on shore holiday resorts to carrying carts. The lifter comprises a bottom frame, an outer supporting pole which is arranged on the bottom frame, a hand shaking capstan arranged on the outer wall at the bottom part of the outer supporting pole, a middle extension pole and an inner extension pole which are limited and do up and down movement in the outer supporting pole, and a cross beam which is arranged at the top part of the inner extension pole. The hand powered lifter is improved by improving winding method between wire cables of an extension capstan and extension poles; compared with the existing extension poles, the inner extension pole in the inner most part of the existing extension pole is completely extended out, the middle extension pole can be extended out, but in the utility model, the middle and inner extension poles are be synchronously extended for being lifting; therefore, the force bearing points of the heavy object can be uniformly distributed on the middle and inner extension poles and the bearing burden of the heavy objects on the inner extension pole is reduced, thereby increasing the lifting weight of the lifters, reducing the resistance of the capstan when shaking by hands and saving labor when shaking by hands.

Description

Hand powered lift
Technical field
The utility model relates to a kind of weight-lifting equipment, carries out the hand powered lift that weight promotes in particular for the level land.
Background technology
Run into the occasion that much weight need be promoted to eminence in the life, for example the building materials on the building ground promotes, perhaps holiday resort by the sea, sometimes need yacht is promoted on the carrier loader and carry away, if only depend on manpower to be difficult to finish, often need promote by gig this moment, and existing gig hangs the crossbeam of doing dipping and heaving and limited middle expansion link and interior expansion link, interior expansion link top in capstan winch and flexible capstan winch, the outer strut bar etc. by the shaking goods on the outer strut bar on underframe, the underframe, the outer strut bar bottom outer wall mostly and constitutes.When promoting weight, shaking goods hangs capstan winch and makes wire rope roll on this capstan winch, the steel rope end that walk around crossbeam two ends assembly pulley this moment can be promoted to eminence with weight by suspension hook, and weight is need be promoted to more eminence sometimes the time, by shaking flexible capstan winch expansion link is stretched out successively, to increase the whole height of gig, thereby satisfy eminence and promote demand, though these gigs promote to weight and bring very big convenience, and field of application is also comparatively extensive, yet in actual use, the stretching out the winding mode restriction that structure is subjected to steel rope and expansion link and have big defective of its expansion link, in the course of the work when the capstan winch tense wire rope, all be after stretching out fully by expansion link in inner most, middle expansion link could then stretch out, this structure makes weight in lifting process, in case interior expansion link fails to stretch out fully, the weight stress point all can only concentrate on the interior expansion link, not only add imperial palace expansion link load-bearing burden, influence the lifting of lifting weight, and can increase the hand resistance of flexible capstan winch, very painstaking when it is shaken.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and provides that a kind of weight load-bearing burden is little, lifting weight is big, the hand resistance of capstan winch is few, shake labour-saving hand powered lift more.
Technical matters of the present utility model is achieved through the following technical solutions:
