Explosion Proof Overhead Cranes

(Explosion Proof Overhead Cranes)

INTRODUCTION

Safety and reliability is especially important in hazardous environments, where safety and efficiency are key. All crane components of our explosion proof cranes are selected to ensure the high level of safety required for the hazardous atmospheres in chemical and petrochemical plants, pharmaceutical, oil refineries, gas power plants, shipyard, waste water treatment plants, paint shops and other industrial sites. Our hoists have been designed and built to provide years of reliable and safe operation.

Modular and Compact Design

• The crane main girder made of computer-optimised box sections, end carriages are made of torsionally rigid, welded box-section design. The Main beam and end beams connect with high strength bolts, our high precision processing equipment ensuring the connection accuracy and make the crane run smoothly.

• The modular design uses a combination of high-quality parts and serial modules to form a rich product specification, modularization, standardization, and mass production mode to ensure product quality, shorten manufacturing period, easy transportation and installation.

• By using compact hoist and high strength materials, the crane has much smaller sizes, wheel load and weight, which can decrease the height of building and reduce the plant construction cost.

• Compact structure, low clearance, small dimension and large work scope, improving production efficiency.

Advanced Manufacturing Technology

• Advanced steel plate pretreatment production line for shot blasting, painting and drying. Shot blasting grade reaches Sa2.5 and surface roughness (Rz) is 40～80μm. Primer spraying will be done within a specified time after the pretreatment to prevent rust, steel materials for main beam, girders will be transferred to fabrication workshop for cutting after pre-process.

• The crane main girder, end carriages and trolley frame adopts our robot automatic welding technology, automatic double-sided intermittent welding technology for the reinforced angle steel weld on the main beam cover web and gantry submerged arc welding for longitudinal weld on the outside of the main beam, all ensuring the highest welding quality.

• The industry leading technology and application of modular interchangeability of crane main girder and end beams.

• The industry leading crane bridge frame and trolley frame processing technology after welding, achieving the high efficiency and stable processing accuracy of the overall crane processing technology after welding.

• The industry leading automatic spraying production line includes three workshops of sandblasting, painting and drying. Safety, reliable and environmental.
