In crane design, we often encounter some crane requirements that need to be met in a specific workplace. As a global crane supplier, we provide customers with customized cranes that will bring solutions to this demand. Today we share a crane case from Malaysia. Hope it can be helpful to you.

Malaysian customers’ demand for overhead cranes
In this case, the customer needed us to provide a design solution for the overhead crane in the existing workshop. Through communication with customers, we need to grasp some key information

It is an existing workshop with concrete columns while without brackets and runway beams for crane, most old warehouse or workshop are not equipped with necessary brackets when they were constructed, which will lead to complicated work when they want to install cranes on. This workshop is over 20 years, before we design 3 ton overhead crane solutions for our customers, we need to know the columns dimensions and inside rebar quantities, model to confirm the columns are strength enough to support the cranes, this is the first most important information client need to supply, because the first target of DQCRANE is to ensure the safety of supplied cranes, which is responsible for client.

Below is the information about 3 ton workshop crane that client need:

After studying the general layout, DQCRANE found that there is limit height of workshop and if we want to achieve the effective lifting height that client required, we need to equip the low headroom electric hoist on the overhead crane, regardless of the site distributions, DQCRAEN finally confirm the lifting height with the low headroom electric hoist, the technical design is as below:

3-ton-overhead-crane-drawing

It is the design with box girder and low headroom electric wire rope hoist, this overhead crane design is now most popular among clients, because from the cost, it is lower than European type overhead crane, but the girder is European girder, which is more stable and less noise comparing with I beam girder.

Low headroom electric hoist can make full use of workshop space, which can perfectly mounted on the box girder.

After confirm the columns information, the second important information is the distance between each two columns, client sent the below layout:

workshop-concrete-column

This layout is very clear and much helpful for our engineers to design solutions. According to the above information, our engineer sent a general distribution design of columns, brackets with cranes on.

DQCRANE are willing to send crane solutions for all workshops, no matter new workshop or old warehouse, if the information is clear enough, DQCRANE technical teams will supply a satisfied crane solution.
