Single Girder Overhead Crane with
Synchronized Control Double Hoists

Single girder overhead crane with double hoists for synchronized control. Tandem operation of the double hoist overhead crane for long & large loads handling.

LDE type electric single-girder overhead cranes are also known as double trolley or duel hoist single girder overhead cranes, among other names. The JB/T306-compliant double hoist single girder crane is designed and manufactured. It is based on the market's and users' requirements in recent years. The LD type general use single girder overhead crane is the foundation for the double hoist overhead crane.

Main specifications of double hoist overhead cranes

• The general lifting capacity of synchromized double hoist overhead crane: 1 ton -25 ton
• lifting capacity of LDE double hoist electric crane: (5+5) ton LDE(5+2) ton , LDE(10+5) ton ,
• the span of the double hoist single girder overhead is 7.5m-31.5m, and can also be designed separately according to user requirements ,
• Crane power supply: three-phase 380V, 50Hz power supply, or customized
• working environment temperature of overhead hoist crane: -25 ℃ -40 ℃.
• Crane control: The operation mode is ground operation, remote control, and indoor operation, which are selected by the user.

The electric hoist is used as the lifting mechanism in this double electric hoist crane. The overhead crane is supported by two rail-traveling end carriages, and the two independent electric hoists are suspended on the lower flange of the single-girder crane beam girder. To meet the various loads handling operations, these two electric hoists can be operated independently or synchronized. It is a very cost-effective method of transporting long and heavy loads. As a result, it is a cost-effective and affordable new type of hoist crane.

• Bridge frame: a box-shaped girder welded by U-shaped steel plate processing and beam steel.
• The double hoist trolley is ideal for lifting long objects (such as utility poles, steel pipes, pipe piles, etc.).
• The operating mechanism of large and small vehicles: it is made up of three rotation modes in one.

Features of double hoist single girder overhead crane

• Compact size;
• Double hoist operation, economical and practical;
• Small size, can effectively use the workshop space;
• The structure of the whole machine is simple, easy to install, use and maintain;
• Light weight and small wheel pressure.
• Lifting range of tandem control duel hoist single girder overhead crane : The common lifting capacity of double hoist overhead crane is 1t-25t, the span is 7.5m-22.5m, three-phase 380V, 50Hz power supply is used, and the working environment temperature is -25°C-40°C. It can also be designed individually according to user requirements.

Hoist synchronization for optimized load handling

It can be essential to run both main hoists simultaneously or simultaneously to realize a tandem operation if an overhead crane with a single girder has two or more main hoists. When the hoisting synchronization mode is in use, both the overhead hoists run and stop simultaneously to keep the load's alignment as it was before the hoisting started. One operator interface concurrently moves two electric travelling hoists in the same direction and at the same speed.

Types of synchronized control double hoist cranes

Tandem opeation double hoist overhead crane with single girder overhead crane design is used for light loads, for long and large loads handling such as, pipe, beam, or steel beam, etc.

Synchronized control double hoist gantry crane with single girder gantry crane design, equipped with two electric hoists for long, large and heavy loads handling indoor use or outdoor applications.

QE Double Trolley Overhead Crane,top running bridge crane usually consists of two trolleys of equal lifting capacity, which can work simultaneously or separately. They are mainly used to lift long and big loads or sets of loads with two long distance lifting points.

Double girder gantry crane with double hoist trolley for outdoor application for large, long or heavy loads handling. And rainproof cover is equipped to ensure your double hoist gantry crane safety.

When the double hoist overhead crane needs to be equipped with two electric hoists, the following items should be considered.

• The capacity of two electric hoists does not exceed the design capacity of the double hoist crane. That is, if you want to hang two 1 Ton electric hoists, the lifting capacity of the double hoist crane should be 2 ton or greater.
• If the total lifting capacity of the double hoist crane is greater than or equal to 1Ton, the reconstruction must be carried out by an enterprise with the necessary qualifications.
• Anti-collision system. For double hoist overhead cranes, the anti-collision devices are needed to ensure the crane operation safety.
• If the lifting item is long, it can be designed with a single switch that can be used simultaneously or individually.
