Features

1. Metal structure

• The main beam adopts U-shaped groove formed by rolling of steel plate or spliced into groove shape. Our company introduced advanced equipment and used the single beam main beam U-shaped groove integral forming technology to reduce the middle butt welding seam and greatly improve the overall structure of the crane. Strength, the application of this new technology, our company has obtained a patent for this model. It is welded with I-beam to form a closed box-shaped main beam. The beam is also rolled into U-shaped grooves with steel plates and then welded into a box-shaped beam. For convenient storage and transportation, the main and beams are transported separately. High-strength bolts are used for on-site installation.

2. Operating mechanism

• The cart of this product adopts separate driving mode, generally four-wheel two-wheel drive. Completed by YSE motor, LD deceleration device, and motor with brake.

3. Lifting mechanism

• It is completed by an independent component electric hoist suspended on the lower flange of the main beam I-beam.

4. Safety and Electrical

• The motor used in this product is a dedicated soft-start motor of Ningbo Xindatong Motor Factory. The control box is a DK1 special electrical control box wired operation on the ground. The running speed is 20m / min. The crane is equipped with safety devices such as: travel limit switch, undervoltage, overcurrent protection, wrong phase protection, emergency switch, etc., which meets the requirements of relevant standards.

• All driving control power supply and driving lighting power supply are powered by isolation transformers according to the relevant regulations, so that the equipment can operate safely and effectively.
