Crane Kits for small capacity top-riding and underhung cranes with electric hoists and bridge controls (electrical panels), end trucks.
which is also called Bridge crane kits, Overhead crane kits, Single girder overhead crane kits, Double girder overhead crane kits.
Just Simply combine components Hoist, End Trucks and Controls as a KIT, it is not traditional COMPLETE Crane Systems. 

A full and complete “crane kit set” for local bridge crane building will included all components needed less the girder. The average kit building time will roughly take twenty (21) hours to build from start to finish. A supplied kit with tailored component packages for efficient single or double-girder and suspension crane solutions that save you time when building. Crane sets must be based on standardized components for simple and user-friendly assembly and contain plug-&-play principle eliminating wiring.

Detailed Description

1. Mechanical  parts
Steel structure: end carriages with wheels driven by motors.
Steel plate material Q235 or Q345B carbon steel (similar with foreign steel plate Fe3 or Fe52).
Main joint adopts union melt welding, nondestructive inspection.
Main girder and end girder adopts bolted connection to ensure strength and accuracy of the whole set.
The trolley and crane adopt three-trinity driving mechanism, frequency stepless speed regulating, hard-tooth surface, disc brake.
Primer and finishing paint, a long service life, beautiful outlook and lustre.
It is in compliance with GB/T 3811-2008 (≈ISO 4301-80 ≈ISO 4302-81)
End truck Duty Cycle: 40% ED.

2. Electrical parts
Safe slide wire provides power conductivity is high and voltage drop is small, and  current collector slidespeed is swift.
Lifting mechanism, trolley and crane can be controlled independently, and work synchronously or individually.
Reasonable layout, simple maintenance for electric control box
Flat cable, galvanized track and cable pulley for trolley traveling power supply, smooth traveling
The multi-wire type fixed cables with plastic insulation are intended for crane usage.
Cables are coded either with numbers, colors or tags for easy identification.
The flat cables used for festoons are PVC insulated flexible flat cables rated for 450/750V, specially designed for cranes, hoists.
Festoon cables are suspended on cable saddles, fixed to cable trolleys, running in a galvanized C-track, which is connected to the main girder with bolted or welded support brackets.
Electric contactless module speed regulation controlling
Smooth traveling, lifting and pushing-on
Pendant control from floor, master control switches in the driver's cabin, with emergency stop
We also offer Variable Frequency Drive (VFD) 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.
Using transducer for travelling or traversing crane to realize step speed or stepless speed change.

3. Lifting mechanism
Electric hoists (mostly electric wire rope hoist instead of electric chain hoist) mounted on main bridge beam.

4. Protection devices
Overload warning and anti-clamp
Sound and light alarm devices
Circuit self-check protector, and flow phase lack protection, Short-circuit protection
Weight overload protection device: include
Emergency stop system: include
Limit switch: included
Voltage lower protection function: included
Current overload protection system: inclued
Brake: when the crane encounter some dangerous,the emergence brake to make the crane stop
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.
Height limiter: effective to prevent the serious personal casualty accidents, ensure the safety of the construction site.
Working temperature within -25 to +42 centigrade.

5 reasons to order an Lightweight Overhead Crane Kit
When you are ready to purchase an overhead crane for your business, it can seem like a daunting task. You have to check out all of the different crane companies, get quotes, schedule an install, and worry about paying for installation. So some businesses don’t even bother with overhead cranes, thinking that they just can’t afford the time or the money that it will take to set one up. What these business owners don’t know is that there is an easier way to do all of this: with an lightweight overhead bridge crane kit. Here are 5 great reasons why any business owner should order an overhead crane kit:

1. Customisation: An overhead bridge crane kit can be designed specifically for your business instead of just purchasing one out of a catalogue or having someone tell you what they have in stock. Instead, an experienced crane service person will help design the perfect overhead bridge crane kit for any business need, large or small.

2. Installation Costs: Suddenly the installation costs are taken out of the equation when a business owner purchases an overhead bridge crane kit. Those extra costs can add up to thousands of pounds with larger cranes and aren’t needed. Overhead crane kits are easy to install and simply plug in when they are needed. There is no need to have professionals install it or hire an electrician to wire it.

3. Faster Delivery Times: Overhead crane kits also offer a faster delivery time than those that have to be scheduled through a crane company. Business owners can choose their own shipping times around their needs and they can choose the shipping options that will cost them the least amount of money out of pocket.

4. Respected Names in Overhead Cranes: Believe it or not, but overhead crane kits are not just unknown names. Business owners can choose from such well respected names like Sky Ram crane kits so they can rest assured that they are getting the highest quality materials with their overhead bridge crane kits.

5. Installation When Desired: Business owners are free to install their overhead bridge crane kits on their own time, not when a crane company says that they have to install it. This gives business owners the freedom to take their time and install the crane right, even if it is midnight.
