Since Dongqi jib crane has been put into market, it won good reputation for Dongqi manufacturer. Dongqi jib cranes have scientific structure, it contributes to save workstation space and cost. To meet the need of modernization, jib boom crane derives into different types such as wall mounted jib cranes, wall traveling jib cranes. You can choose what you need according to your plant condition.
And Dongqi jib cranes are of high quality, we adopt high strength steel to make sure that steel structure can bear lifted loads in case of deformation or damage of jib cranes. Dongqi manufacturer also provide you free assembling guidance and training. Besides, you can get a year warranty for you whole jib crane.
Jib type crane is designed to meet the need of density transportation in short distance. This crane has compact structure, and it is safe, high efficient and fixable. Because of its outstanding advantages, it is widely accepted on types of industries, plants, port and warehouses.
As a light and medium duty lifting machine tool, the working class of most jib devicce is under A5. Dongqi manufacturer has many models of jib cranes to meet your need of different occasions, pillar mounted jib crane, wall mounted jib crane and wall travelling jib crane are hot sale featured products. Moreover, if you want an easy crane, Dongqi gives you portable and mobile jib crane. If you want a jib crane with two jib arms, Dongqi double arms jib crane can get more loads lifted in a time. Here are the brief introduction of three featured jib lifting tool.
Following is the series of jib canes divided in details, you can choose your own one bellow, contact us now for high quality jib cranes with good price.

Pillar jib crane
Pillar mounted jib crane
Pillar mounted jib cranes, also call column jib cranes, floor jib cranes. This jib device belongs to fixed jib crane that supporting by fixed column on the ground. Common duty pillar jib can carry loads below 5 tons, and its longest turning radius limits in 5 meters. If you want lift heavier objects, a heavy duty jib crane is the best choice, this heavy duty model has similar appearance with common column jib crane. The only difference lies in a slewer device, with this device, huge duty crane is able to transport heavy loads easily.
Both pillar jib cranes and heavy duty cranes have a supporting jib boom, which is helpful for changing force condition, and make the control of jib easier. Besides, supporting jib arm resolves the force of jib base, which makes bending moment of jib head releasing. Turning device is installed o the end of jib arm, and positive wheel pressure prevents drive from slipping and in an accurate start and braking position.
Head of pillar connects jib boom with bearing structure, so that boom can turn smoothly. In addition, this crane use collector conductive ring, which makes jib arm moving in a 360 rotation. Bottom of pillar jib adopts flange base, which connects groun flange with bolt, this crane design makes jib device has a strong and reliable connection, and convenient to maintain.
Jib girder uses steel joint, except ensuring strength and rigidity, which can reduce self-weight, so that pressure of the whole machine can reduce. Dongqi adopts CD or MD electric hoist as lifting device. This jib hoist is easy to operate and maintain. You can choose a remote control or use hand operation.
Tons of Jib Cranes
5 ton jib crane
2 ton jib crane
1 ton jib crane
Wall jib cranes
Wall jib cranes includes wall travelling jib cranes and wall mounted jib cranes, they are the development of fixed pillar jib cranes. Wall mounted jib crane is mounted on wall or a concrete pillar. Triangle structure makes wall mounted jib strong, and compact structure saves plant space largely.
Wall travelling jib cranes develop based on wall mounted crane, instead of fixed on wall, this crane is able to travel along rails on wall, which prolong the working range. This crane suits for density assembling line well.
Requirement of machinery and steel structure
1. Jib crane’s steel structure has reasonable design, optimized structure, and it confirms to requirement of strength, rigidity and stability. Besides, its design takes full consideration for the influence of environment.
2. Steel structure uses welding truss structure. For steel material, Dongqi uses Q235B or Q345B constructional steel. All material used has material report and relevant certification.
3. Design of steel structure has to take full consideration of the possibility of manufacturing, examining, transporting, installing and maintaining.

Safety regulations of jib cranes installation
- All high strength bolts have to tightening rightly, high strength bolt cannot be replaced by common bolt.
- Bolts fastener have to be replaced after five times replication.
- Never lubricate Bolts fastener.
- All bolts fastener have to be tightened when put into use for one to two months. And broken bolts should be replaced.
- Check connection of dowel, and all rabbet should be outward. Or electric hoist maybe wear down.
- Hoist and hook device should adopt soft connection way hanging on jib boom, for iron link may have force out of force, which can break hoist down.
- Dongqi jib crane use flat cable. Moreover, insulated wire and the grounding conductor of the cable
- Should pain into yellow green.
- The grounding conductor of the cable cannot bolt for tighten, and grounding connection point should prevent from loose.
