QZ Type Grab Bucket Bridge Crane

Description

QZ Type Grab Bridge crane is widely used in loading goods in port, factory, workshop and power plant.

The work classification is heavy .The group classification of the crane is A6.The direction of platform door to the driver’s cap is: side, end and top. The lifting capacity includes the weight of the grad.

It is only suitable for bulk materials in natural stacking conditions. If grabbing the materials under the water or special materials, they must be specialized when ordering.

Features

1. High security

The safety protection devices are complete, including limit switches, overload protection devices, emergency stop devices, etc. for lifting and CT, to ensure the safety of the operation; During operation, variable frequency control can be carried out to ensure the safe movement and landing of goods;

2. Flexible operation and stable performance

The gears in the reducer adopt helical gears, which can be automatically lubricated and have better equipment flexibility; Can be remotely controlled for easier operation;

3. Strong stiffness and good quality

The steel plate raw materials are made of products from top tier factories, with stable and guaranteed quality, low failure rate, and better adaptability to special working conditions;

4. High work efficiency and good durability

Adopting laser assisted height measurement technology for more accurate positioning; High level of work, supporting all day work and demanding work demands.

Technical Data

Options And Components

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.

Trolley

Crane trolley is a load-bearing equipment that can travel along the running track, transport goods, and lift operations. It is usually used as a supporting component for large lifting equipment such as bridge cranes, gantry cranes, gantry cranes, and cantilever cranes. It is mainly used for logistics handling and heavy lifting operations in factories, docks, shipyards, and other places.

Grab

Grab refers to a specialized tool used by a crane to grab dry and loose goods. The container space is composed of two or more bucket shaped jaw plates that can be opened and closed together. When loading, the jaw plates are closed in the material pile, and the material is grabbed into the container space. When unloading, the jaw plates open in a suspended state on the material pile, and the material is scattered on the pile. The opening and closing of the jaw plates are generally controlled by the steel wire rope of the lifting mechanism of the crane. Grab bucket operation does not require heavy physical labor, can achieve high loading and unloading efficiency and ensure safety, and is the main dry bulk loading and unloading tool in ports. According to the type of homework goods, they can be divided into ore grab, coal grab, grain grab, wood grab, etc

Crane remote control

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