I. Hoisting Tests:No-load test run: When the electric hoist is raised or lowered along the beam and stopped at any height, there must be no downward slippage; the upper limit position of the hoist must be calibrated, and the accuracy of the limit switch position verified.Rated load test: Before test
Before installing the pillar-mounted jib crane, verify the product and technical documentation against the packing list to check for any missing items or damage. Any bending, twisting, shaft rusting, or impact damage caused during transport must be corrected or restored. Additionally, rotating parts
I. Pillar-Mounted Jib CraneAlso known as a column-mounted jib crane, this equipment offers a lifting capacity ranging from 125 kg to 5,000 kg and can be custom-designed to meet specific customer requirements. It is a widely used type of jib crane. Characterized by a novel, rational, and simple struc
Generally, a single-girder model is recommended for applications with a lifting capacity under 50t, a span within 35m, and no special operational requirements. A double-girder gantry crane is preferable if wide gantry legs are required, high operating speeds are needed, or if heavy, long, or large l
Operating a crane requires extensive experience to prevent unnecessary accidents. Therefore, practical insights based on experience are invaluable. Below is a summary of essential crane-related information compiled by experts, which we hope you find useful:1 What are the primary safety protection de
For light-duty cranes, oil is their lifeblood; however, severe oil leakage is currently a common issue with this type of equipment. Here, Qingdao Wanli Hoisting Machinery discusses the causes of oil leakage in crane gear reducers.Let’s take a look at the issue of oil leakage in light-duty cranes!I.
The crane consists primarily of tracks, suspension devices, a traveling trolley, and various functional components—all of which are standardized modules. The lifting mechanism typically utilizes an electric chain hoist, though it can also support equipment such as robotic arms or welding torches, f
The concept of "lightweighting" originated in the automotive industry. Due to the correlation between a vehicle's dead weight and its fuel consumption, lightweighting gradually became a driving trend in automotive design. Since then, this trend has spread to other manufacturing sectors
Electric chain hoists have a wide range of applications across industries such as manufacturing plants, warehouses, wind power, logistics, shipping terminals, and construction. They are used for lifting, loading, and unloading cargo, as well as for hoisting heavy objects to facilitate work or the re
The quality of a chain hoist's initial manufacturing determines its service life; however, maximizing its longevity during actual operation requires proper maintenance and inspection. Effective maintenance not only extends the equipment's lifespan but also enhances operational flexibility.Th
Cables designed for cranes and traveling hoists are suitable for mobile electrical equipment operating at AC rated voltages of 450/750V or lower. Their construction allows for frequent bending without kinking or tangling, making them ideal for applications such as festoon systems (traveling cables)
Chain hoists are increasingly popular due to their lightweight yet durable nature and features such as gears that have undergone high-temperature quenching. They represent a new generation of lifting equipment. Here is a brief overview of the causes behind gear abnormalities in chain hoists.There ar
