Workstation Double Girder Overhead Cranes 130/60 Ton For Hydropower Industry

Workstation Double Girder Overhead Bridge Crane 130/60 Ton for Hydropower Industry

Overhead crane is a kind of lifting equipment which is used to lift materials horizontally over workshop, warehouse and stock yard. Because its two ends are located on tall concrete columns or metal brackets, the shape is like a bridge. The main girder of the overhead crane runs longitudinally along the track laid on the viaduct on both sides, which can make full use of the space under the bridge to lift materials without being hindered by the ground equipment. It is the most widely used and the largest number of lifting machinery.

Main Features:
1. NANTE Double girder overhead crane follow FEM standard.
2. Nante design and fabricate the main girder which combines light weight construction with heavy weight strength, power and durability.
3. Can use double girder hoist or winch which can achieve until M7 duty group.
4. Nante use bogie end carriage which will make the long travel of crane to be more smooth than long end carriage.
5. The control panel follow IEC standard, and can use all inverter control for lifting, long travel, and cross travel.
6. Except load limited switch, rotational limited switch, cross limited switch, nante can design the dual brake system and dual height limitator for double safety.

Design features include:

DESIGN:

Compact dimensions, low weight, easy to operate and easy to maintain, modular design with direct fits between components

Structure:

Bridge Girder, End carriages, Crab Frame manufactured from box plate design / Rolled Sections. If required 100% radiography of all butt welding joints of bridge and end carriages can be provided.

MOTORS:

Nante Crane uses sturdy cylindrical/ conical rotor pole-changing motors with elegant continuous cast aluminum sections, integrated safety brakes insulation class F, IP54 protection.

Variable Frequency Drives & Remote Controls –

We also offer Variable Frequency Drive in hoisting, cross travel, long travel for stepless speed control as an optional feature. We also provide radio remote control cranes for application in inaccessible and hazardous areas.

Brakes :

Failsafe magnetic or hydraulic brakes of 150% torque or more are fitted on shaft extensions. For heavy duty cranes a second brake can be mounted to ensure failsafe operation.

Controls :

Pendant control from floor, master control switches, master controllers in the driver's cabin can be provided. Radio remote control can be provided on request.

ELECTRICAL PANEL:

Modular design, covering a very wide operating range. The systems are designed for ease of installation and maintenance and reliable operation, with fuseless circuitry, ducted wiring and non-screwed terminals. Each drive group is equipped with a motor overload protection device to provide effective protection against inadmissible overloading.

PAINTING:

Every component & part is thoroughly scrubbed & painted with two coats of primer before assembly & two coats of synthetic enamel after testing.

LIMIT SWITCHES:

To prevent over hoisting & over lowering of hook.
