single girder overhead crane electric hoist lifting

Electrical control box :

The control box surface has been treated with preservatives

Rational layout, ease of maintenance

Protection IP44,IP45,IP54,IP55.

Ambient temperature: <45 ° C, humidity <90%

The main power supply is optional

All wires have color, digital or line number for easy identification

All external cables marked with a line

Fixed cable installed in the walking line or it has protective casing(galvanized steel)

single girder overhead crane electric hoist lifting Rolls and wire rope:

Large Diameter

Welding reel, light weight

The ratio of the diameter between rolls and wire rope can reach to 46(Traditional is 27)

The big curvature of the wire rope extend its life

Precise positioning heavy objects, less Offset

High-strength galvanized steel wire rope,

Breaking force 2160kN/mm2

Wire Rope no need coated anti-rust oil, Maintenance-free, clean

Ductile iron guide rope device,less abrasion for wire rope, long life

single girder overhead crane electric hoist lifting Security slide wire:

Corrosion resistant, Insulating outer covering closed campact trolley line

High conductivity, low pressure drop

Light weight, ease of installation, no maintenance

Operating Temperature Range:From -30°C to +60°C

Relay device high glide speed, to ensure continuous power supply

single girder overhead crane electric hoist lifting Running triple motor:

Squirrel-cage type frequency conversion motor

Protection Grade IP45,electrical connection sustained rate 60%ED

Smooth operation, it will reduce the heavy objects shaking when starting and variable speed.

Hard-toothed surface, low noise design

Disc type brakes

single girder overhead crane electric hoist lifting Girder

Humanization optimization design

The thickness of all the sheet material is tested by ultrasonic,

Control the thickness strictly

Numerical control design completely

Arch degrees curve smooth

Tire frame forming-box technology, little deformation

Automatic welding, nondestructive flaw detection

Whole beam shot dealing with,Grade Sa2.5, eliminate the welding stress

Epoxy zinc-rich paint,the life is above 10 years.

The color of the girder: optional
