Description

Technical Parameters

The MZ type grab bucket gantry crane is a lifting equipment commonly used for handling bulk materials in large outdoor sites. It is particularly suitable for processing blocky or irregular materials such as coal, ore, and sand/gravel.

It consists of several components including the main girder (which can be single or double girder structure), legs, end carriages, travel mechanism, hoisting and opening/closing mechanisms, grab, electrical system, and safety protection devices. These components work in coordination to achieve highly efficient mechanized handling of bulk cargo.

When selecting this type of equipment, it is necessary to specify key parameters such as lifting capacity, span, and lifting height, as well as details like the power supply method for the gantry travel (safety conductor rails or cable reel), and the position and door opening direction of the operator's cab.

Features of MZ Type Grab Bucket Gantry Cranes

High Operational Efficiency

Achieves continuous operation of bulk materials through "grasping, lifting, moving, and unloading".

Integrated Functions

A single unit integrates three major functions: loading/unloading, transportation, and stacking.

High Space Utilization

The space under the gantry can be fully utilized for material stacking or vehicle passage, enabling three-dimensional space utilization. This is particularly suitable for cramped sites or expensive port and terminal areas.

Wide Adaptability

By replacing with different types of grabs (such as two-jaw grabs for coal and sand/gravel, multi-tine grabs for large-sized ores, timber grabs for logs, etc.), it can handle various types of bulk cargo and some long-length goods.

Flexible Operation

Operation can be selected from either the operator's cabin or via remote control.

Robust, Durable, and Easy Maintenance

The box-type double girder structure offers great rigidity and strength, enabling it to withstand frequent and heavy-duty operations.

Major mechanisms (such as hoisting and opening/closing) feature a high degree of modularization, facilitating inspection and maintenance.

Applications of MZ Type Grab Bucket Gantry Cranes

Ports and Inland Waterway Terminals

Used for loading and unloading bulk commodities like coal, ore, grain, and fertilizer. It serves as the primary handling equipment in bulk cargo terminals.

Thermal Power Plants

Used in the plant's coal storage yard for stacking and reclaiming coal, feeding the coal handling system for the boilers.

Metallurgical and Steel Plants

Handles the unloading, storage, and transfer of raw production materials like iron ore, limestone, and coke in the raw material yard.

Building Materials and Construction Engineering

Sand and Aggregate Yards: For handling, loading/unloading, and storing building materials like sand and crushed stone.

Large-scale Water Conservancy, Hydropower, Highway, and Bridge Construction Sites: Processes sand and aggregate near concrete batching plants.

Railway Freight Yards and Logistics Centers

Specifically used for the rapid loading and unloading of bulk materials from railway gondola cars (e.g., coal cars, ore cars).

Other Industrial Fields

Can be found anywhere involving large-scale bulk material handling, such as wood chip yards in pulp mills and fuel storage yards in waste-to-energy plants.

MZ Type Grab Bucket Gantry Crane

	Main Girder The core load-bearing component of the bridge structure, typically constructed as a box-type single or double girder structure. It spans across the two legs, providing the runway for the trolley travel. Its strength and rigidity determine the overall stability and lifting capacity of the crane.
	Outrigger The columns that support the main girder and connect to the end carriages. Classified by structure into L-type and C-type, they effectively accommodate track irregularities and prevent structural binding.
	Travel mechanism Divided into Gantry Travel (longitudinal movement of the entire crane along the tracks) and Trolley Travel (transverse movement of the trolley with the grab along the main girder). The combination of these two movements enables the crane to position the grab arbitrarily within the track area.
	Crane Trolley Comprises two independent winch systems (the hoisting drum and the opening/closing drum) along with wire ropes. By controlling the coordinated and alternating actions of these two rope systems, the grab's descent, material grabbing, hoisting, and unloading are achieved.
	Operator's Cab Typically suspended under the main girder, it houses the control levers and instruments.
	Grab Bucket Used for handling bulk materials. Its jaws open and close via wire rope or hydraulic actuation, and it can be exchanged according to the characteristics of the material being handled.
