Advantages of Double Trolley Double Girder Crane For Long and Heavy Loads Handling

High flexibility is provided for long items handling:Great flexibility is provided by the double trolley overhead cranes for long objects handling. There are two hoist trolleys used as the lifting mechanism of the double girder overhead crane which can handle items horizontally and vertically at same time or separately.

Up / down, Left/ Right:The overhead crane trolley mechanism which is consisted of an electric hoist and a top running trolley, offers two directions of load motion, up or down, left or right.

Separately or simultaneously: The Heavy duty overhead crane with double girder & double trolleys is combined of a main hoist trolley and a secondary hoist trolley, which can be operated together for complex conditions such as installation process and also can be used separately with the same functions as a common double girder overhead crane with a hoist trolley.

Economical solution for complex lifting situations

• Reliable heavy duty overhead crane with double girder & double trolleys is efficient and stable in working performance at cost-effective crane price.For actual engineering projects, there are often complex lifting conditions such as the handling of long items or items with long lifting points which need the cooperation of two overhead cranes which increases the investment for the workshop. Comparatively, a Heavy duty overhead crane with double girder & double trolleys is able to solve such problems perfectly but with low crane cost and investment in plant construction.
• And also with advantages of compact structure and light dead weight, Heavy duty overhead crane with double girder & double trolleys is easy to storage, transport, and also easy to install and maintain, which also makes the double trolley double girder overhead crane competitive in terms of crane price and crane cost.
• Lastly, the Heavy duty overhead crane with double girder & double trolleys is available in cut-to-tail crane designs, which is able to at the largest extent to satisfy your needs of lifting requirements without spending extra-money Due to the unique features and advantages, the double trolley double girder overhead cranes has a wide application range.

Features of Double Girder Overhead Crane with Double Trolleys for Synchronize Operation

And the features of the double trolley double girder overhead cranes are as following:

• Crane girder : Due to the box welded structure design, the crane bridge girder is with high degree of rigidity vertically and horizontally.
• Crane travelling mechanism： Separate driving is adopted with high flexibility. Strong beam and stable travelling mechanism ensures the good performance of the trolley cranes.
• Soft starter motor is used in the travelling mechanisms of bridge crane and travelling trolleys.
• The emergency switch can stop any movement at once by pressing on the single button to prevent danger effectively.
• The overhead trolley crane is rely on the crane bridge frame to move logitudinally along the rail direction of the workshop and the hoist trolley are moving along the main beam direction transversely while the lifting hook of the hoist trolley are used to lift up and down of the loads.

Main Structure and Components and Customized Options

Heavy duty overhead crane with double girder & double trolleys is mainly consisted of crane bridge beam, driver's cab, trolley travelling mechanism and electric equipment. The driver's cabin has three open directions: side, top and end.

Double Trolley Crane Design Options

• Crane runway of double trolley crane : elevated runway beam
• Long travelling operation & trolley cross travelling operation: electric
• Hoisting trolley of double trolley crane: electric wire rope hoist or electric chain hoist or open winch
• Crane control: crane pendant, wireless remote control / wireless radio control or / and crane cabin control.
• Safety device of trolley crane: overload limiter, travel limit switch, anti-collision device, etc.

Hoist Trolley Options for Double Girder Overhead Cranes

Crane hoist trolleys are designed for double girder overhead crane and are widely used for heavy duty lifting operations with higher safety and stability. The hoist trolley are runs on along the top of edge of two girders and the wire rope with hook will descend between the two girders to handle the load, which enables the maximum possible height of lift under the beam girder, however, on the hand more roof space will be required above the crane beams or girder, due to it sits on the top of crane beam girders.
