Lifting Equipment – A Comprehensive Look

The performance of primary and secondary manufacturing operations, comprehensive mechanization and automation of production processes in all areas of the economy would be unthinkable without the use of a wide range of lifting equipment. Modern in-line technology and automated production lines, interdepartmental intrashop transport, loading and unloading operations in warehouses and trans-shipment points are organically linked with the use of various types of lifting systems – transport machines and mechanisms to ensure the continuity and rhythm of production processes. Therefore, the use of this equipment largely determines the efficiency of modern production and the level of mechanization of technical production – degree of excellence and productivity.

With modern production intensity can not ensure its steady rhythm without a coherent and reliable operation of the means of transportation of raw materials, semi-finished and finished products at all stages of processing and storage.

There is a wide variety of lifting machines designed for all kinds of operations: vertical and horizontal transportation, at any distance and weight. The crane device typically consists of a series of successive operations: the capture of a single piece of cargo,lifting, moving to the necessary position and getting back to the starting position to capture the next cargo and its subsequent lifting and moving.

Lifting and moving can be performed both continuously and sequentially (cycles). The correct choice of the lifting equipment is a major factor in normal operation and high efficiency. Modern high-lifting machines with high speed and increased load capacity keep on popping out in the market due to a high demand. Thus, Granada Material Handling, a seasoned manufacturing, lifting equipment inspection and lifting equipment services expert business, reports of 12% increase in line-up positions since the year of 2012.

Powerful hydraulic jacks

Hydraulic jacks, as the name implies, run on liquid. These jacks are different in design and feature an actuator. Its main bearing elements: a body extendable piston (plunger) and a working fluid (usually hydraulic oil). The housing is a guide for the piston cylinder and a reservoir for the working fluid. Strengthening of the crank handle is transmitted through the lever on the fuel pump. When moving up liquid from the reservoir is fed into the cavity of the pump and is pumped into the pressing cavity of the working cylinder, pushing the plunger.

The advantages of hydraulic jacks include rigidity, stability, smoothness, braking precision, large capacity, compact, little effort on the drive handle, high efficiency (0.75-0.8). Hydraulic device allows you to lift loads with a minimum height of almost a base structure. It expands the scope of its application as compared with the mechanical jacks. Disadvantages are quite significant as well: low speed, low altitude ascent in one working cycle, design complexity. Another difficulty is inability to accurately adjust the height lowering. Furthermore, such jack is subjected to way more serious breakages in comparison with mechanical lifting devices. In addition, this type of equipment is offered at a considerably higher price.
