Description

MG Type Double Girder Gantry Crane (Truss-type) is made up of bridge, trolley, crane traveling mechanism and electric system.Applies to highway, bridges, power station and other Construction workshops for general handling and lifting operations. All institutions are indoor controlling, crane electric form is devided into two kinds of cables and sliding contact line, you can choose any one when you order it.

Double girder gantry cranes ; It is preferred and used seriously in every branch of the industry due to its cost, ease of maintenance and repair,no capacity limit, no size limit, design and manufacture with desired features. Much higher lifting heights can be obtained compared to single-girder gantry cranes. Double girder gantry cranes can be produced as protruding or without protrusion.
Although Portal Cranes are generally used in open fields, they can also be used in the factory. It is an alternative application to overhead cranes in factory indoor areas. Gantry cranes has more advantages than jib cranes acoording to scanning area. Gantry cranes , also called marble cranes, are suitable for all kinds of lifting and stacking works in open areas.

Features

Reasonable structure

Favorable performance

Smooth starting and stopping

Safe and reliable traveling

Low noise, commodious cabin and good view

Convenient maintenance, excellent exchange ability for parts and components

Saves electricity specifications

Our Gantry Cranes are completely designed by our own engineers in accordance with ISO, FEM and DIN norms. Mechanism selections are made in accordance with the desired lifting and running speeds and working class. Bridge beam deflection is calculated as 1/1000 at most. By having a quieter and more sensitive bearing system compared to its alternatives, it increases the life of the roller, wheel and gear box, and thanks to the adjustable wheel center, it can provide +/- 15 mm movement in the centers where there are rail defects.

Components

- Electric Trolley
  
  Hoist trolley usually installed on the heavy duty bridge crane or gantry crane as a lifting mechanism. It has a simple structure and light weight. It’s mainly used in general hoisting, loading and unloading operations in machinery manufacturing workshops, warehouses, assembly and hydro-power station maintenance.
- Main beam
  
  The main beam is the crane's main load-bearing component, and the running track for the electric hoist. It is a triangular beam is weld by a support frame(welded by angle steel and other section steel) and an I-beam. The two sides of the span are designed with saddles connected to the outriggers, and there are rectangular steel plate connecting flanges. There are buffers at both ends of the main beam to ensure the safe operation of the trolley on the main beam.
- Crane Hook
  
  Crane hook is the most common type of spreader in lifting machinery. The crane hook is often suspended on the wire rope of the hoisting mechanism with the help of pulleys and other components. The crane hook should conform to the manufacturer's suggestions and must not be overloaded.
- Wheel Set
  
  The wheel set is a mechanical device consisting of a wheel and a shaft, a bearing and a bearing housing. The crane wheel set is generally used for the vehicle to support the crane and the load, and at the same time, the crane is allowed to perform the reciprocating running operation on the specified track.
- Crane Cab
  
  The crane cab is the workplace of the crane operator and it undertakes a crucial role. The design of the cab fully considers the comfort and safety of the operator. It has a good view so that the operator can clearly observe the surrounding environment and operating conditions.
- Control model
  
  Can use control handle with pendant line, wireless remote control, or cabin control.
