What is an Electric Hoist?

An electric hoist is a compact, lightweight, yet powerful lifting device crucial in industrial production and logistics. It utilizes electric motors to lift and horizontally move loads, operating both independently or integrated into various cranes (overhead, gantry, jib). Widely used in factories, warehouses, and construction, capacities range from 0.1 to 80 tons（Customizable） with lifting heights of 3-30 meters.   Core Components:​​ Drive Unit:​​ Primarily electric motors (common types: conical rotor motors for inherent braking, or reliable squirrel cage motors). Transmission:​​ Gear systems (often hardened alloy steel in cast iron housings) transferring motor power to the lifting mechanism. Lifting Mechanism:​​ Contains the drum/wheels for wire rope/load chain, and a forged steel hook with safety latch. ​​Braking System:​​ Essential safety feature, typically spring-applied, electrically-released brakes (e.g., disc or cone brakes) acting immediately on power loss. Mechanical brakes secure loads when stopped. ​​Control System:​​ Electrical components (contactors, relays, buttons, limit switches, overload protectors) managing start/stop, direction, and safety functions.   ​​Key Classifications:​​ ​​By Drive:​​ Electric (common, efficient) or Manual (no power required). By Lifting Medium:​​ Wire Rope Hoist (higher capacity/speed, e.g., CD single-speed, MD dual-speed for precision) or Chain Hoist (compact, low maintenance). By Mobility:​​ Fixed (lift only) or Traveling (lift and traverse...

What Is a Column Mounted Jib Crane?

In industrial production, material handling, and various engineering construction scenarios, the column mounted jib crane, with its unique structure and excellent performance, holds a very important position. It is like a tireless steel guardian that accurately and efficiently completes various lifting and transporting tasks within limited spaces. It is deeply integrated into the modern industrial system and has become an essential key piece of equipment.   I. Basic Definition of Column Mounted Jib Crane   The column mounted jib crane, also known as the fixed column jib crane, is a light and small lifting device fixed on the ground. It is specially designed for short distance and high frequency lifting scenarios. Its core features are compact structure and flexible operation. It uses a vertical pillar as the support point and a horizontal boom for material handling. It is particularly suitable for factories, workshops, warehouses, and other places with limited space and high operational frequency.The boom can rotate around the pillar, flexibly covering a certain working area and achieving efficient material lifting and transportation.   II. Main Structure of Column Mounted Jib Crane   The structure of the column mounted jib crane is exquisite and scientific. All components work together to...

What is the main purpose of gantry crane?

Gantry cranes, also known as gantry hoists, are extremely versatile heavy-duty material handling equipment. Their unique gantry-style structure enables them to handle and load/unload heavy objects within a large spatial range, featuring stable structure, strong load-bearing capacity, and flexible operation, playing an indispensable role in numerous fields.   I. Port and Wharf Operations Against the backdrop of booming global trade and increasing port cargo throughput, gantry cranes have become the core force for cargo loading and unloading in port terminals. As the main mode of modern port logistics, container transportation relies on gantry cranes to precisely lift containers from ships, place them onto transport vehicles at the wharf, or lift and transport them from the yard to designated positions on the ship. Their lifting height and load capacity can meet the loading/unloading needs of containers of different specifications, greatly improving container handling efficiency.In large container ports: Shore bridge gantry cranes are used for ship loading/unloading operations at the wharf front, quickly transferring containers from ships to transport vehicles at the wharf front. Rubber-tired gantry cranes are responsible for yard operations, moving containers to the yard for storage or waiting for transshipment. The two work closely together to enhance the overall...

Do you know the difference between these two types of cranes?

In the field of industrial production, single beam cranes, as a common material handling equipment, play a key role in improving production efficiency and reducing physical labor intensity. With the development of technology, European single beam cranes have gradually emerged, forming a clear contrast with traditional ordinary single beam cranes. Below, a detailed analysis will be conducted from various aspects such as design concepts, structural characteristics, manufacturing processes, performance, applicable scenarios, and costs, to help you gain a deeper understanding of the differences between the two and make appropriate choices based on actual needs. 1、 Design concept and design standards The European single beam crane adheres to advanced design concepts and strictly follows the European Union’s EN13001 series standards for crane design. With precise calculation as the core and advanced technologies such as finite element analysis to optimize material distribution, we aim to achieve a high degree of fit between the overall force model and structural design, pursuing comprehensive optimization goals of safety, reliability, efficiency, and energy conservation. Our structure is compact and the stress distribution of components is balanced. For example, a 10 ton European style single beam crane customized for a large equipment assembly workshop has a total...
