LDZ Type Single Beam Grab Crane

Description

The LDZ electric single-girder grab crane is a single-girder crane that uses a grab as a lifting device. This type of single-girder crane is equipped with twin electric hoists for the grab. It is widely used in various occasions such as factories, warehouses and material yards to lift bulk cargo. The rated lifting weight is 2~10t, the span is 4.5~28.5m, and the working environment is -20℃~+40℃. It is prohibited to use it in flammable, explosive, corrosive media and other environments.

The operation mode of LDZ single-girder grab crane is on the ground or in the driver’s cab.

Working Condition

1.Metal structures and mechanical parts should have sufficient strength, stiffness and buckling resistance.

2. It is required that parts and metal structures are not damaged after being loaded. For parts such as steel wire ropes with complex stress states, static strength calculations are usually carried out based on the main load and main deformation form, and a higher safety factor is used. It must also be required that the deformation of the component under the action of the load is within the allowable range, that is, There should be sufficient stiffness.

Second, the whole machine must have the necessary stability against overturning.

3. The prime mover has the power to meet the operating performance requirements, and the braking device should provide the necessary braking torque.

Features

Technical Data

Spare Parts

Main beam

The main beam is a box beam or H-beam structure, welded and formed from steel plates. The steel plate material is domestic steel (Q235B). The vertical winding is in accordance with Chinese national standards. All steel plates are subjected to shot blasting pre-treatment to achieve Sa2.5 level standardization. Before welding, the steel plates are carefully inspected and cleaned, usually by automatic welding machines (MIG or semi-automatic welding).

End beam

End beam is a supporting structure designed for lifting machinery, usually located at both ends of the crane, and its function is to provide stable support and balance for the crane. Cranes need to bear enormous weight and inertial forces during operation. Without the support of end beams, the crane is prone to imbalance or even overturning. Therefore, the role of the crane end beam cannot be ignored, as it is one of the key components for the safe operation of the crane.

Electric hoist

The electric hoist will do dynamic and static load tests, as well as ascending and descending pressure tests. The baking paint process is used to enhance the adhesion of the paint film and improve the appearance quality. The assembly line ensures product quality.

Crane remote control

Industrial wireless remote control is a remote wireless remote control device specifically used to control construction machinery or industrial equipment.

Crane control box

The surface of the control box has undergone anti-corrosion treatment Reasonable layout for easy maintenance Protection level IP55 Environmental temperature:<45 ° C, humidity<90%
