The kbk crane is used in conjunction with the kbk rail to easily move and lift heavy objects, which is safe and labor-saving. To ensure efficiency operation and material handling safety in your workstation, the following we will go into the installation environment requirements, operation requirements and safety rules, and kbk crane system installation and maintenance, etc.
Types of KBK crane systems for your selection
KBK light crane system includes KBK monorail suspension crane, KBK single girder suspension crane, KBK double girder suspension crane, KBK telescopic girder suspension crane, KBK stacker crane, rigid kbk crane system, and combined-type KBK cranes, and other forms, etc.
kbk rail operation environment conditions
The rated lifting capacity is the maximum loading capacity of the kbk crane, and overloading is not allowed. The rated lifting capacity includes the lifting load weight and self-weight of spreader used if any is used.
Standard KBK crane system are suitable for workshop operations, and the ambient temperature is -20℃~+40℃. Special measures should be equipped for customized crane system that used in applications at ambient temperatures other than -20°C to +40°C, outdoor and corrosive environments, etc.
Operation environments requirements for kbk crane installation
- The installation environment of the kbk rail should be spacious and bright, which is not only conducive to the installation of the track, but also ensure the kbk rail to operate safely.
- The kbk rail cannot be installed in a humid environment, and the installation workshop should be dry and well ventilated.
- There should be no chemical corrosive substances in the workshop where the kbk rail is installed, so as not to cause corrosion to the kbk crane components.
Environments not suitable for kbk rail installation
In order to ensure the durability of the crane, what kind of environment is not supposed to install the kbk rail system?
- Kbk cranes should not be installed and used in environments with humidity, high temperature and dust.
- The humid environment has high air humidity, and the surface of the crane is easy to adhere to water droplets, causing rust to the crane parts.
- the high temperature environment will speed up the wear of the kbk crane parts, reduce the work efficiency, and shorten the service life of the parts;
- if the dust adheres to the kbk crane Long-term non-cleaning can also cause corrosion to the components, causing the crane to rust.
- The kbk crane should be installed in a dry, normal temperature and clean room, so as to reduce the damage of components and prolong the service life.
Requirement for kbk rail crane system operations
Personal requirements: The operators and maintenance personnel of flexible combined kbk cranes must be 18 years old and above, with normal intelligence and body. They have received training in equipment operation and maintenance, and read this manual.
KBK Crane system Inspection before operations
In order to ensure the safe and efficient operation of kbk cranes , careful inspection should be carried out before operation. The following inspection list is presented for your reference.
- Check whether the kbk crane equipment is firmly installed, and clean up the sundries around the equipment to ensure the smooth operation of the kbk rail .
- Check whether there are rust, cracks and other phenomena on the kbk track to ensure that the rail crane can operate safely.
- Check whether the hoisted heavy objects are firmly tied to avoid falling during operation.
- Check that the power supply is stable and the equipment can operate normally to ensure that the kbk rail crane can carry out the lifting operation normally.
Operation requirements:
- When it is confirmed that there is no danger, the operator turns off the power switch, releases the emergency stop button on the flashlight door, and turns on the crane power.
- Check control devices, limit devices, brakes, lifting mechanisms, operating mechanisms, buffers, etc. (See electric hoist operation manual and other related documents)
- Only when the crane operators confirm that the load does not exceed the rated lift weight, the crane can be operated. The hooks or slinging should ensure that the load does not slip or fall.
- For manually operated cranes, only by using the push-pull trolley or hooks to move the trolley. And it is not allowed to move the trolley by pulling the wire of pendant control.
- Be sure to use flexible connection among the load, hoisting rope and hoisting hook. Rigid connections will generate additional forces on the parts, resulting in fatigue fracture of the parts. The diameter of the ring used to connect the special spreader and the hook should be large enough to prevent the hook from being stuck.
- During operation, the stop buffer should be used frequently to stop the operation.
- When finishing the operation, the following operations must be performed: the crane should be moved to the storage position; all loads should be released, and the special spreader, grab bucket, electromagnet and suction cup should also be placed on the ground; press the emergency stop button; cut off the power switch of the crane.
- It is the operator's responsibility to check the crane equipment for obvious damage at least once per shift, stop using it immediately, and report the damage to the relevant personnel.
Don’ts for kbk crane operations
- The kbk crane is divided into various models, and the appropriate model is selected according to the tonnage of the heavy object to be lifted, and overload operation is strictly prohibited.
- The working environment of the kbk rail crane should be spacious and bright, so that the operator can always observe the lifting status of the heavy object to be lifted, so as to avoid danger during the lifting process.
- The kbk crane lifts the heavy objects vertically, and the inclined-pull lifting will cause the heavy objects to shake, and in serious cases, there may be a danger of falling.
- The moving speed of heavy objects should not be too fast during the lifting process, so as to avoid hitting other objects and causing them to fall.Only with standardized operation, kbk cranes can ensure the safe and efficient lifting of heavy objects, improve work efficiency and improve the safety of operations.
- The kbk rail crane system is not allowed to transport people.
- It is not allowed to lift the load above personnel.
- It is not allowed to pull or pull the load at a certain angle.
- No lifting is allowed when you are uncertain the load weight exceeds the rated capacity of the kbk crane or not. .
- The chains or wire ropes of the electric hoist are not allowed to be used for winding and lifting loads.
- It is not allow ed that the actual operating staff to leave when the load is in the air.
- Do not use the safety device as an operation stop device. (e.g. slip clutch, chain end stop, limit switch)
- If the kbk crane is found to have malfunction or abnormality, it should stop working immediately.

What factors will affect the safe operation of the kbk crane system ?
Familiar with the working environment - The kbk rail crane should be installed in a spacious and bright workshop, and the indoor fully meets the hoisting operation conditions. The installation position should not have obstacles that hinder the movement, and the width is suitable for the crane to move.
Operation method. - Carefully read the crane's operating instructions before operation. The installation instructions must be standardized. When lifting heavy objects, no staff should stand or walk under the heavy objects, so as to avoid the heavy objects falling and hurting the workers, and the safety of the operation must be ensured.
Product quality. - When choosing a high-quality kbk crane, the product quality is directly related to the safety of the operation. The high-quality crane can be used safely for a long time, and it is not easy to be damaged and avoid accidents.
The above points are the factors for the safe operation of kbk single-girder suspension cranes. I hope everyone can pay attention. If you have other questions, please call for consultation.
Anti-swing control of crane operation
When it comes to KBK cranes, many people may know it, but if it is specific to the anti-sway control method of the crane, many people may not be clear. The KBK crane is a popular crane in the market in recent years, and many people are more interested in it. Let's take a look at the specific methods of KBK crane anti-sway control.
KBK crane anti-sway control is used based on the needs of the crane operation, the operator sends the controller the operation instructions , and based on the running speed and frequency, to control the travelling speed to reduce the anti-sway control of the crane.
This method makes the hook and load not sway after the KBK crane moves from the stop state to the specified speed at a constant speed, and also makes the hook and the load not sway after the crane moves from a constant speed to the stop state, and the crane reaches a uniform speed from a standstill. Short control adjustment times for motion and dynamic processes from uniform motion to stop.
How to prevent kbk crane from tilting?
The tilting of the kbk rail during operation will cause heavy objects to fall and parts to be damaged. So how to prevent the kbk rail from tilting during use?
- The road of the kbk rail must be flat and firm, and the parking position must be flat.
- The kbk rail is installed firmly and the screws are tightened to prevent the track from tilting during the operation.
- Overload operation is strictly prohibited on the kbk rail. Long-term overload operation will increase the bearing load of the components, causing the track components to tilt.
- Clean up the surrounding debris before operation to ensure that the heavy objects can run smoothly.
- The above is the method to prevent the kbk rail from tilting. If you have other questions, you can call for consultation.
