Recently, HSCRANE delivered a customized portable gantry crane to a client. They are in a precision machining zone in Ho Chi Minh City, Vietnam. The client undertakes precision OEM business for multinational auto parts and heavy industrial accessories. The workshop is densely packed with high-value CNC machining centers and milling machines. Due to surging orders, the production line runs at full capacity 24 hours a day.
In daily processing, operators frequently lift metal blanks and semi-finished fixtures. These weigh from 300kg to 800kg, and go onto CNC machine workbenches. The factory originally relied on a single 5-ton overhead crane. It handled material flow for the entire production line. However, the crane frequently handled lifting tasks for various processes. This caused long waiting times for CNC operators during loading and unloading. Severe machine downtime directly slowed down the overall utilization rate.
In addition, the internal equipment layout of the workshop is very compact. Operating space left for heavy lifting equipment is extremely limited. The client tried installing a pillar jib crane. But the factory foundation lacked thickness for high-strength chemical anchors. The long modification period also forced them to abandon this plan. They faced realities of unbroken floors, narrow spaces, and frequent independent lifting. Introducing a flexible, non-interfering lifting plan became an urgent need to boost capacity.

Our technical engineers analyzed the client’s site drawings and had video communications. We recommended a 1-ton portable gantry crane with a motorized electric chain hoist. This plan has several core advantages. It perfectly matches the special working conditions of the machining workshop:

We checked the factory headroom, CNC door span, and max lifting weight. All technical indicators underwent strict stress verification and customized design. The specific parameters are shown in the table below:

The portable gantry crane uses a modular bolt connection design. After arriving at the client’s factory from Ho Chi Minh port, assembly began. The internal maintenance team used a forklift to finish assembly and testing under 2 hours. They put it into production use on the same day.
After three months of actual operation, the Vietnamese machining factory manager reported an excellent experience. Average loading and unloading times in the CNC workshop dropped by about 40%. The overall utilization rate of the machines improved significantly. More importantly, standard lifting equipment completely replaced dangerous practices. Some stations previously used manual hoists and tripods illegally. This greatly reduced safety risks in the workshop. It provided solid logistical support for the high-intensity machining line.
