Offset trolley single girder crane

This product consists of a box-type main beam, end beams, a trolley, and a running mechanism. The electric hoist is installed on an angular trolley as the lifting mechanism. The angular trolley is arranged in a cantilevered configuration on one side of the main beam for operation. The trolley is equipped with upper and lower horizontal wheels, which are arranged in a three-point configuration with the vertical travel wheels. The position of the electric hoist has been elevated from below the main beam to the upper side of the main beam, effectively increasing the lifting height. The trolley's movement is controlled by a conical motor brake and an open gear transmission. The main beam adopts a box-type structure with offset tracks, equipped with upper and lower horizontal wheels, ensuring safety and reliability while preventing track damage. The travel mechanism of the main beam adopts a separate drive configuration, utilizing a conical motor brake and an open gear transmission.

The electric single-girder suspended crane consists of a main girder, end beams, an electric hoist, and an electric trolley, all fabricated from steel plates and I-beams. It is suspended from the I-beam tracks on the upper part of the factory building, with a cantilever length of 0.5 to 1 meter. The electric hoist operates along the lower flange of the main beam's I-beam, performing material handling tasks. It features a lightweight structure and convenient installation and maintenance, making it widely used in production workshops, warehouses, and cargo yards. The work class is A3-A5.

Electric single girder crane

The electric single-girder crane consists of a main beam, end beams, an electric hoist, and a traveling mechanism, all fabricated from steel plates and I-beams. The electric hoist runs along the lower flange of the I-beam on the main beam to perform material handling operations. It features a lightweight structure and convenient installation and maintenance, making it widely used in various settings such as factories, warehouses, and material yards for material handling. It is prohibited from use in environments with flammable, explosive, or corrosive media. The duty cycle is rated at A3-A5. Operating modes include ground-mounted handles, wireless remote control, and a driver's cab. The driver's cab is available in open and closed configurations. The main crane operation uses separate drive systems, cone-type motor brakes, and open gear transmission.

Electric hoist bridge crane

The electric hoist bridge crane consists of four main components: a box-type bridge frame, a main hoist travel mechanism, a trolley, and electrical equipment. It features a fixed electric hoist mounted on the trolley frame as the lifting mechanism. The trolley travel system uses LD-type transmission, while the main hoist travel system is available in two types: LD-type transmission and QD-type transmission. The structure is simple and lightweight, featuring a compact overall height and light self-weight. It is suitable for use in factories, workshops, and warehouses with medium to small lifting capacities. Operating methods include ground-based handles, wireless remote control, and a driver's cab. The driver's cab is available in open and closed configurations.

Rotating beam bridge crane

Used for handling long slabs, bars, and other black metals. Rotation is achieved through two forms. One form is beam rotation, where the beam is a double-layer structure. The upper beam is connected to a pulley system and steel wire rope, while the lower beam is equipped with multiple electromagnetic clamps or grippers, which can rotate to a certain angle with the drive mechanism. The other form is trolley rotation, where the trolley has a double-layer structure. The upper trolley is equipped with a lifting mechanism, while the lower trolley serves as a running trolley with a circular track installed on it. The upper trolley can rotate along the circular track.

Electromagnetic hanging beam bridge crane
This crane is designed for lifting long steel ingots, plates, bars, coils, and other items using a suspended beam. It is equipped with an electromagnetic suction cup, clamps, or special hooks for lifting operations. The crane primarily consists of a box-type bridge frame, a hoisting trolley, a main travel mechanism, an operator's cab, and an electrical control system, and is fitted with a power failure magnetic retention system. The hoisting mechanism typically employs a single motor, dual reducers, and dual drums arranged in a dual lifting point configuration. The gantry beam arrangement can be either perpendicular to the main beam or parallel to the main beam. Other configurations are identical to those of the QD-type crane.

Double trolley bridge crane
The difference between a double trolley bridge crane and a hook bridge crane lies in the fact that the main beam is equipped with two trolleys. The two trolleys can be operated independently for lifting and movement. When lifting long items, the synchronized lifting and movement can be achieved by switching the control panel's conversion switch.

Electromagnetic bridge crane

The basic structure of an electromagnetic bridge crane is the same as that of a hook bridge crane, with the exception that a DC lifting electromagnetic suction cup is suspended from the hook. This suction cup is used to lift and transport ferromagnetic black metals and their products. An AC power source is converted into a DC power source via a thyristor DC power box installed in the driver's cab. The DC power is then transmitted to the electromagnetic suction cup via a dedicated cable reel mounted on the trolley.

Grapple bridge crane

The grab bridge crane primarily consists of a box-type bridge frame, a grab trolley, a main hoist travel mechanism, an operator's cab, and an electrical control system. The material handling device is a grab. The grab trolley is equipped with a hoisting mechanism and an opening/closing mechanism, with the grab secured by four steel wires wound around the hoisting and opening/closing drums, respectively. The opening/closing mechanism drives the grab to close, enabling it to pick up materials. Once the grab opening is closed, the hoisting mechanism is immediately activated, distributing the load evenly across the four steel wires to perform the lifting operation. During unloading, only the opening/closing mechanism is activated, causing the grab opening to open and tilt the materials. Except for the hoisting mechanism, the remaining structural components of this crane are essentially identical to those of a hook-type bridge crane.

Hook-type bridge crane
The hook-type bridge crane is currently one of the most widely used types of lifting equipment. It primarily consists of a box-type bridge frame, a hoisting trolley, a main crane travel mechanism, and an electrical control system. The lifting device is a hook. Rails are laid on the main beam to allow the hoist trolley to move horizontally along the direction of the main beam.
