Characteristic analysis of European wire rope electric hoist

1、 Structure and Design: Compact and Efficient, Maximizing Space Utilization

Modular and compact design

The European wire rope electric hoist adopts modular manufacturing technology, with highly integrated core components such as motors, reducers, and brakes, forming a "three in one" drive system. This design significantly reduces equipment volume, reduces self weight, lowers wheel pressure, and can cover a larger operating range within the same factory building, improving space utilization. For example, its C-shaped structure layout allows for parallel arrangement of drums and motors, resulting in smaller ultimate dimensions, making it particularly suitable for low clearance environments.

Double rope structure

Both ends of the drum are synchronously wrapped with steel wire rope to ensure stable lifting of the lifting device. This structure reduces lateral bending, reduces wire rope wear, and extends service life by optimizing the rope groove design (such as a rope diameter ratio of 20 and a rope groove radius of 7mm). The rope guide is made of high-strength nylon material, symmetrically arranged to prevent jumping and further ensure smooth operation.

2、 Performance and Efficiency: Efficient transmission, energy-saving and environmentally friendly

High transmission efficiency

Hard tooth surface reducers and gear grinding machines (with precision up to level 6) reduce energy loss and increase transmission efficiency by 15% -20% compared to traditional products. The internal gear hardness of the motor reaches HRC60 or above, significantly enhancing wear resistance and reducing maintenance frequency.

Variable frequency and dual speed control

Equipped with variable frequency drive or dual speed motor as standard, it supports micro speed and inch movement functions to achieve precise positioning of goods. For example, the lifting speed of the 3.2t/5t model reaches 7m/min, which is higher than similar domestic products (5m/min), and the operating efficiency is improved by 40%.

Energy conservation and environmental protection

The overall energy efficiency level of the machine reaches level 2, which complies with the EU energy-saving standards. Aluminum alloy shell design accelerates heat dissipation and extends motor life; Maintenance free steel wire ropes and brakes reduce the use of lubricating oil and lower environmental pollution.

3、 Safety and reliability: multiple protections, worry free operation

Safety control device

Lifting height limiter: measures the number of rotations of the drum through an encoder, accurately calculates the load height, and automatically stops at the preset upper limit position.

Overload protection: The customized overload limiter has a sensitivity of 110% -125% of the rated load, and immediately cuts off the power and alarms when triggered.

Anti slip rope device: The gap between the rope guide and the steel wire rope is strictly controlled to prevent slipping from the groove; The friction clutch integrates a speed detector to ensure that the chain does not slide down in case of abnormal conditions.

Braking and Protection

Electromagnetic disc brake: maintenance free design, fast and smooth braking, double sealed housing to adapt to harsh environments.

Protection level IP55: Excellent dustproof and waterproof performance, ensuring stable operation of the electrical system.

Redundant design

The dual encoder system forms redundancy with two sets of safety control devices to avoid accidents caused by a single fault. For example, synchronous monitoring of motor encoders and drum limiters improves system reliability.

4、 Maintenance and Cost: Low consumption, long-lasting, and outstanding economic efficiency

Maintenance free components

The key components such as gearbox, brake, friction clutch, etc. have a maintenance free cycle of up to 1900 hours, reducing downtime for maintenance. The sprocket adopts a plug-in connection, which can be quickly replaced without disassembling the motor, and the maintenance efficiency is increased by 50%.

durable materials

The steel wire rope is made of wire contact, interactive twisting, and galvanized hemp core material (such as 6X36WS-FC-1770), with a tensile strength of 2160N/mm ² and a lifespan extended by three times; The hook has undergone hot forging treatment and is designed to rotate 360 ° with a safety tongue to prevent detachment.

Data based operation and maintenance

The operation supervision module records data such as motor temperature and operating status, and provides early warning of faults. Modular design enhances the universality of spare parts and reduces inventory costs.

5、 Environmental adaptability: wide temperature range operation, wide scene coverage

temperature range

The working environment temperature ranges from -25 ℃ to+40 ℃, suitable for extremely cold or high temperature areas. For example, it can still start normally in a Nordic -25 ℃ environment and continue to operate at a high temperature of+40 ℃ in the Middle East.

Protection level

The IP55 protection standard ensures stable operation of equipment in humid and dusty environments, suitable for harsh scenarios such as docks and metallurgy.

6、 Customization and scalability: flexible adaptation to meet diverse needs

Model and specifications

We offer a lifting capacity of 1-80 tons and a lifting height of 1-50 meters, with work levels covering M5/M6, and support for single speed and variable frequency dual speed configurations. For example, the X series is suitable for single beam cranes, while the F series adopts a universal C-shaped structure and is compatible with multiple types of cranes.

Intelligent upgrade

Optional black box device, automatically records operational data, supports remote monitoring and fault diagnosis. Variable frequency technology enables multi speed regulation, suitable for high demand scenarios such as precision manufacturing and aerospace.
