The indoor-outdoor dual-purpose four-column linear sliding hoist is a common type of lifting equipment. Below is an introduction to it: Structure Composition: It is mainly composed of a lifting beam, main engine, trolley, push-pull rod, four columns and crossarm. Working Principle: The motor drives the trolley to move horizontally along the track of the lifting beam, and at the same time, the lifting and lowering of goods are realized through wire rope traction. The straight-in and straight-out track design allows goods to easily extend out of windows and cross obstacles such as awnings, achieving the hoisting of goods both indoors and outdoors. Product Features: Compact Structure: Small size, light weight, low noise and easy to move. It can be used in small windows as narrow as 30 cm, with a maximum outreach distance of 1.6 meters outside the window. Strong Stability: The four-column structural design ensures high load-bearing capacity, effectively enhances overall stability and reduces shaking during the hoisting process. Easy Operation: When equipped with a pressure plate main engine, the clutch can be operated with one hand to realize rapid lowering. It can also be used with a wired switch or wireless remote control.

Wide Applicability: It can be powered by either 220V or 380V, and the wire rope length can be selected from 30 meters to 100 meters. It is suitable for various scenarios such as construction sites, decoration projects and household moving.
