Top Running Bridge Cranes

Top Running Bridge Cranes

Explosion-proof top running bridge cranes are special overhead cranes used in hazardous environments where flammable gases, liquids, or dust are present. These cranes are designed to prevent the occurrence of sparks, arcs, or any other source of ignition that could trigger an explosion or fire. They are equipped with various safety features that ensure the crane and its operators are protected at all times.

The construction of explosion-proof bridge cranes involves the use of non-combustible materials, such as stainless steel, aluminum, or brass. The electrical components are often housed in explosion-proof enclosures and designed to prevent any potential sparking. The hoist motors and controls are typically explosion-proof certified and can operate safely in hazardous areas.

The essential safety features of explosion-proof bridge cranes include spark-resistant components, such as wheels, bearings, and hooks made from copper, bronze or other non-sparking materials. Electrical equipment is equipped with grounding to prevent static electricity buildup, which can ignite flammable gas and dust. The cranes may also have flameproof enclosures, which help protect the crane from potential sources of ignition.

The specific explosion-proof points are as follows：
 

1. Explosion-proof measures are adopted for the mechanical parts. In order to prevent friction and high-temperature sparks generated by the impact of the electric hoist during operation, the relevant parts are treated.
 

(1) Inject an appropriate amount of mechanical oil into the hoisting and running reducer.
 

(2) Apply grease to the reel and wire rope.
 

(3) The left and right stop blocks on the limit rod and the limiter socket of the limiter are made of bronze-plated or stainless steel.
 

2. The surface temperature of the electric hoist during normal working hours does not exceed 110°C.
 

3. The electrical components of the electric hoist include: lifting and running motors, control boxes, control buttons, limiters, etc. all adopt self-contained flameproof equipment.
 

4. Adopt soft cable type power introducer.

Explosion-proof top running bridge cranes are used in different environments, including petrochemical plants, food processing facilities, paint manufacturing plants, and other industries that deal with hazardous materials. They are typically operated by experienced and trained crane operators, who follow the standard guidelines for working in hazardous environments.

Introduction to the main features of explosion-proof beam cranes

Main feature:

(1) The bridge frame adopts box-shaped main girder, which is welded by automatic submerged arc welding.

(2) The electric conduction of the trolley adopts a new I-shaped steel track cable conduction device, which is safe and reliable.

(3) The lifting mechanism can also be equipped with a second set of safety devices according to requirements. Increased reliability.

(4) Standardization, serialization and generalization of parts and components.

(5) The operating room has a wide field of view, and all mechanisms are operated in the operating room, making the work comfortable and flexible.

This product is widely used in the loading and unloading of ordinary heavy objects, and it can also be equipped with a variety of special spreaders for special operations. It is equipped with rainproof equipment when used in the open air.

Top Running Overhead Cranes are divided into two working systems: intermediate (A5) and heavy (A6) according to the busyness of use. When selecting, the technical requirements such as the working system, the highest and lowest temperature of the working environment and the type of power supply should be indicated, and it can also be designed and manufactured according to the span required by the user.

Explosion-proof top running bridge cranes are essential for the safety of employees working in hazardous environments. These cranes are designed to meet the strict safety standards and regulations put in place to protect workers. Choosing the right explosion-proof crane can help prevent workplace accidents, injuries, and fatalities, and ensure a safer working environment.
