20T European Type Double Girder Crane, Crane Manufacturing Expert Products

Introduction

European type cranes have such design concepts as small dimension, light dead weight. Compared with traditional cranes, the limiting distance is minimum from hook to wall, and headroom is the lowest, which makes cranes work more close to the front, and lifting height more higher that increases effective working space of workplace.

New workshops can be designed more smaller and have more functions because the dead weight is light, and the wheel pressure is small. Smaller size workplace means saving a huge amount of money from initial construction investment, long-term heating, air conditioning and other maintenance free.

Smooth and stable traveling

A variety of patterns meet customers’needs

Mechanical parts

Double main girder, welding box structure, camber meeting national standard

Steel plate material Q235 or Q345B ( similar with foreign steel plate Fe3 or Fe52).

Main wels joint adopts union melt welding, nondestructive inspection.

After welding, main girder is through shot blasting treatment, gets Sa2.5 class, and eliminate welding stress.

Main girder and end girder adopts bolted connection to ensure strength and accuracy of the whole set.

The trolley and crane adopt trinity driving mechanism, frequency stepless speed regulating, hard-tooth surface, disc brake.

Crane driving IP55, F class insulation, contact continuity reaches 40% ED.

Epoxy zin-rich paint, a long service life, beautiful outlook and lustre.

Crane buffer block, anti-derail end plate

Electrical parts

Safe slide wire provides power whose conductivity is high and voltage drop is small, and current collector slide speed is swift.

Lifting mechanism, trolley and crane can be controlled independently, and work synchronously or individually.

Reasonable layout, simple maintenance and insulation class IP55 for electric control box

Flat cable, galvanized track and cable pulley for trolley traveling power supply, smooth traveling

Electric contactless module speed regulation controlling

Smooth traveling, lifting, and pushing-on

Lifting mechanism

European standard electric hoist with wire rope

Protection devices

Overload warning, secondary class anti-clamp

Cranes with buffer

Sound and light alarm devices

Circuit self-check protector, and flow phase lack protection

Operation

Several operation ways such as: ground flashlight door, remoter, flashlight door+remoter, etc.

Ground operation is simple, no need of professional operators, and operators have more freedom on the ground.

Double stop button or rocker type joystick

Customers can choose what they need.
