Mobile Gantry Crane Second Hand

1. Product Introduction:

 

MZ mobile gantry crane second hand also known as grab bucket crane, grab bucket gantry crane, grab bucket gantry crane, grab bucket overhead crane, has a lifting capacity of 5 tons, 10 tons, 16 tons, 20 tons (t), etc. It can be used for loading and unloading bulk materials, with high production efficiency and convenient operation. Widely used in workplaces such as ports, stations, power plants, mines, material yards, and ships. According to the type of grab, it can be divided into mechanical grab and electric hydraulic grab. This machine is prohibited from use in flammable, explosive, and corrosive media environments. This product has two operating forms: ground and control room. The control room has two types: open and closed. It can be installed on the left or right side according to the actual situation. The entrance direction has two types: side and end, to meet the needs of users in various situations.

 

2. Component:

MZ mobile gantry crane second hand is mainly composed of gantry, cart operating mechanism, lifting trolley (double hook) and electrical parts.

The bridge adopts a box-shaped double-girder welded structure and a π-leg welded structure, which not only enhances the overall stiffness and bending resistance, but also increases the working space and facilitates transportation, installation and maintenance;

The operating mechanism of the cart is driven separately and consists of a motor, reducer, brake, wheel set, etc., and is installed at both ends of the bridge.

The trolley is composed of a motor, reducer, brake, wire rope, pulley block, hook, etc., and walks along the track above the main beam.

The electric conduction of the trolley adopts a special-shaped rail cable conduction device;

The cart adopts the sliding contact line type and the cable reel type for selection; the closed air-conditioning operation room is used, and the linkage control table is installed inside.

Electrical equipment uses standardized, universal and serialized parts, which facilitates maintenance and replacement and extends the service life.

 

3. How to choose a MZ mobile gantry crane second hand

Please refer to the following parameters:

Lifting capacity: 20T, 32T, 50T, 60T, 70T, 80T, 90T, 100T, etc., can be customized according to user needs.

Span: 7M, 8M, 9M, 10M, 12M, 13M, 15M, 19M, 20M, 21M, 22M, 29M, etc. The appropriate span can be selected according to site conditions.

Working level: A5 or A6, able to adapt to higher working frequency and larger load.

Working environment: temperature -25℃～+40℃, relative humidity not exceeding 85%, altitude not exceeding 2000m.

Cart operating speed: 20m/min or 30m/min, frequency conversion speed regulation can be used to achieve smooth lifting and walking.

Trolley running speed: 40m/min or 60m/min, frequency conversion speed regulation can be used to achieve smooth lifting and walking.

The lifting speed of the trolley: 5.9m/min or 7.2m/min. It can adopt variable frequency speed regulation to achieve smooth lifting and walking.

Conductive form: cable or slide wire, the user can choose any one.

 

4. Applicable Environment:

The MZ mobile gantry crane second hand is used for the loading and unloading of bulk cargo in outdoor freight yards, material yards, ports, coal mines, sand factories, and other areas. Work level A6, operating methods include wireless remote control and cab operation

 

It can also be equipped with a variety of special spreaders for a variety of special operations, such as magnetic cranes, grab buckets, electromagnetic beams, etc.

5. Transportation process:

(l) Plan the transportation method.

Based on the specific conditions of on-site lifting machinery and vehicle transportation, a practical and effective logistics transportation plan will be formulated.

(2) Design, conceive and manufacture logistics transport racks.

According to the total weight and external dimensions of the 60 ton gantry crane, various types of prefabricated steel or wooden logistics transport frames (support frames) are produced.

The regulations require a simple and clear structure, scientific and reasonable logistics and transportation endurance, relatively stable, low center of gravity, light weight, saving stainless steel plates, and easy and fast assembly and disassembly.

(3) Check the reinforcement during logistics transportation.

According to the requirements for confirmation of the transportation plan, check the crack resistance of the double-girder gantry crane at the most unfavorable cross-section to avoid gaps during transportation. If the crack resistance is not enough, appropriate structural reinforcement should be carried out Processing.
