Abstract
Univerzalna dvoradna ručna dizalica za građevinare, radi tako što obrće vitlo (20) u oba smera pokretanjem radne poluge (4). Osnovni element je pretvarač kretanja sa zupčanicima (9) i (10) koji se okreću u smeru skazaljke na satu, te lančanicima (2) i (3) na suprotnoj strani. Poluga (4) koja je vertikalno postavljena ima na gornjem kraju mehanizam sa kočnicom čijim se pomeranjem menja brzina rada u zavisnosti od opterećenja. Letva (1) je izvedena u lučnom obliku što obezbeđuje neprekidni zakretni momenat. Pri laganom spuštanju tereta koristi se kočnica (23), s tim što se prethodno izvuče letva (1) iz zahvata zupčanika (9) i (10).[The lift works by revolving the winch (20) in both directions by moving the working lever (4). The basic elemnt is the transformer of movement with cog wheels (9) and (10), that are evolving clockwise, and chain wheels (2) and (3), on the oppostite side. Lever (4), which is vertically placed, has the mechnism with brake on the top, that is used for changing the speed of the work in dependence of the load. The batten (1) is performed in the shape of an arch, which provides constant torque. To lower the load gently, use break (23), but first pull out the batten (1) from the grip of the chain wheels (9) and (10).
