Abstract

The invention relates to a crane for lifting cold winding adhesive tapes, which relates to a crane. Both ends of a cross beam (4) are connected with two bases (7) respectively by upright posts (5), a hoisting hook (3) is hooked in a lifting ring (13), one end of a rope (11) is wound on a crank capstan (12), and the other end of the rope (11) extends upwards along the upright posts (5) so as to erect on a pulley (10), then passes through a fixed pulley (9) with a base and then passes through the hoisting hook (3) so as to be fixed to a shackle (2). According to the crane, a pulley block, the hoisting hook and a balance hook are arranged on a portal, the crank capstan is arranged in the middle of the upright posts, the balance hook is hooked by utilizing the hoisting hook, and the rope is connected with the hoisting hook and the crank capstan, so that the purposes that a lifting effect is achieved by utilizing the crank capstan, a moving effect is achieved by utilizing a roller and the polyethylene cold winding adhesive tapes are easily moved are realized.

Description

【Technical field】 [0001] The invention relates to a crane, in particular to a crane used for hoisting cold-wound tape rolls. 【Background technique】 [0002] Cold wrap tape, also known as cold wrap tape. It is named after its application, which can be wound at room temperature, that is, cold wound. Because the tape is generally used as an external anti-corrosion material for steel pipelines, it is widely used in the field of pipeline anti-corrosion. It is made of polyethylene, so it is also called polyethylene cold-wound tape. The composite polyethylene anti-corrosion cold-wrapped tape is made of polyethylene calendered film and butyl rubber layer by co-extrusion and heat extension. Due to the use of polyethylene calendering process The mechanical strength of the base material polyethylene is increased, butyl rubber has excellent air tightness (the gas permeability is only 1 / 20 of natural rubber), and butyl rubber has unique self-melting adhesion among all rubbers, so that ...
