Introduction
Small workshops are often limited by tight headroom and floor space. In cramped environments, manual handling or simple hoists slow down production. They also create high risks like falling loads or crush injuries. Selecting the right crane dictates material flow and manufacturing costs. Improper selection causes space conflicts or workstation congestion. Accurate matching maximizes vertical space and boosts Overall Equipment Effectiveness (OEE). For compact conditions, jib crane and single girder overhead crane are the two main solutions. The former focuses on high-frequency lifting at workstations, while the latter covers large spans across the shop floor.

What is a JIB CRANE?
The engineering logic of a jib crane is simple. It uses a fixed pivot as the center to provide material rotation and lifting within a specific radius. It does not span the entire workshop. Instead, it solves high-frequency handling pain points within the “last ten meters” of a workstation.
How Jib Cranes Work
Based on how the pivot is anchored, jib cranes mainly come in three structural forms:
- Pillar-mounted:This type uses classic flange anchor bolts on a concrete foundation to support loads independently. It offers the strongest capacity and usually provides full 360° rotation coverage.
- Wall-mounted:This type mounts directly onto existing steel or concrete pillars in the workshop. Its biggest engineering value is “zero floor space.” It never interferes with forklifts or walkways below, usually providing about 180° of semi-circular coverage.
- Mobile:This type features a heavy counterweight base at the bottom, so it requires no foundation digging. A forklift can move it at any time, making it ideal for temporary workstations or flexible layout adjustments.
Key Features of Jib Cranes
Beyond empty specs, jib cranes are favored in small workshops because they are fast, accurate, and cost-effective.
- Extreme Space Efficiency:Both zero-space wall-mounted types and compact pillar types survive in tight machine gaps. They maximize the effective working area of the workshop.
- Shorter Cycle Times:Instead of waiting for an overhead crane to travel across the shop, workers have the jib crane right at hand. Precise operation within a fixed radius boosts efficiency for light loads (often 0.25t–5t) and high-frequency cycles.
- Very Low Infrastructure and Installation Costs:The structure is modular. There is no need to assess workshop load capacity or install long runway beams and corbels. This slashes both initial investment and installation time.
Typical Applications
If your workshop fits the following scenarios, a jib crane is usually the highest ROI choice:
- Machining and Welding Stations:Workpieces go on and off machines frequently. Operators need immediate equipment access and cannot waste time queuing for the main workshop crane.
- Assembly Line Nodes:It allows precise hovering and micro-positioning when assembling parts like engines or gearboxes.
- Maintenance and Testing Stations:It serves local heavy component disassembly and repair, acting as a tireless “steel assistant” for technicians.
What is a Single Girder Overhead Crane?
If a jib crane is like a “capillary” for specific workstations, a single girder overhead crane is the “main artery” managing logistics for the entire workshop. It is not limited to a fixed radius. Instead, it provides comprehensive material handling support across the factory floor.
How Single Girder Overhead Cranes Work
The mechanical language of a single girder system is very clear. It mainly consists of a main girder, end trucks, a crane traveling mechanism, and an electric hoist. Its operational logic builds a three-dimensional coordinate system (X-Y-Z axes) covering the workshop:
- X-axis (Long-distance dispatch):Supported by end trucks on both ends, the crane travels linearly along rails mounted on the workshop’s longitudinal columns (corbels).
- Y-axis (Span coverage):The electric trolley carrying the load travels along the lower flange of the main girder, moving across the width of the factory floor.
- Z-axis (Vertical lifting):The drum and wire rope (or chain) perform precise lifting in the vertical dimension.
This orthogonal rectangular travel path means that any physical coordinate on the workshop floor within the range of the runway beams and rails can be covered without dead zones.
Key Features of Single Girder Overhead Cranes
Compared to heavy-duty, high-cost double girder equipment, single girder overhead cranes offer excellent cost-effectiveness and structural flexibility in small workshops, especially those with limited headroom:
- Zero Floor Interference & Headroom Maximization:Rails are installed mid-air, saving busy ground walkways and machine clearance. Paired with a low-headroom electric hoist, it maximizes effective lifting height in low-ceiling factories.
- Wide Capacity and Span Adaptability:Though it has a single girder, it handles core loads from 1 to 20 tons. The main girder span can be customized to fit the factory structure (usually between 7.5m and 28.5m), covering over 90% of heavy lifting needs in small factories.
- Doubled Logistics Efficiency:Long-travel crane speeds can reach 20m/min or higher, smoothing the workflow from raw material receiving to processing and final product loading.
- Automation Integration:Modern single girder cranes use Variable Frequency Drives (VFD) for smooth starting, stopping, and anti-sway control. Control interfaces connect smoothly with workshop automation or PLC systems.
Typical Applications
When materials need to travel across different zones instead of just going on and off a machine, a single girder overhead crane becomes essential:
- Metal Processing and Stamping Plants:Handling heavy steel coils and large plates during unloading and feeding. These tasks rely heavily on the crane’s wide horizontal coverage and off-center load handling.
- Machinery Manufacturing Workshops:Moving large parts like equipment chassis and frames over long distances between different assembly lines or bays.
- Injection Molding Shops:Positioning heavy molds precisely during installation. Micro-speed lifting via VFD prevents mold damage and is crucial here.
- Warehouse and Logistics Zones:Managing fast stacking, inventory moving, and high-frequency loading or unloading in storage areas.
Jib Crane vs. Single Girder Overhead Crane: Core Differences Compared
When asking for a quote, clients often ask us: “To lift a two-ton load, should I buy a jib crane or go straight for a single girder overhead crane?” There is no absolute winner between the two. Their engineering designs determine their best uses. To give you a clear view, we have broken down the core metrics of these two machines:

How to Decide Which Crane Fits Your Workshop Best?
Many clients ask us for a 5-ton crane price quote right away. However, choosing equipment without knowing your layout and workflow is highly irresponsible. Before designing blueprints, we always ask clients to confirm these five key metrics first:
5 Crucial Factors to Evaluate Before Choosing
- Actual Maximum Lifting Capacity:If you lift 2 tons daily but swap a 4-ton mold occasionally, you must plan for 5 tons. For small workshops, if a single load exceeds 5 tons, a jib crane’s pillar size and foundation cost skyrocket. In this case, going with a single girder overhead crane is often more cost-effective.
- Daily Lifting Frequency (Interference Rate):How long do workers spend using the pendant control daily? If loading and unloading happen constantly, give them a dedicated jib crane. Otherwise, everyone waits for the main crane, leading to hidden and costly downtime.
- Workshop Dimensions and Headroom Clearance:Older factories often have tight headroom. If the ceiling is low, a single girder crane needs a low-headroom hoist to save space. If the factory lacks load-bearing pillars, a pillar-mounted jib crane with its own foundation is your best lifesaver.
- Lifting Path (Travel Trajectory):Do your materials move within a circular radius or do they need to travel diagonally along the X-Y axes of the workshop? Choose a jib crane for the former and a single girder crane for the latter.
- Need for Multi-Workstation Coverage:If material must leave Machine A and fly across most of the workshop to Welding Station B, you definitely need a full-coverage single girder overhead crane.
Real-World Case Studies
Looking at real-world scenarios is better than discussing theory. Here are three typical workshop conditions we at HSCRANE often encounter, along with their optimal solutions:
Case 1: Small Maintenance Station
- Site Pain Points:Fitters frequently disassemble motors and gearboxes weighing 500kg to 2 tons. Using a large overhead crane is too clumsy. Long wire ropes also sway too much during precise alignment.
- Optimal Solution:Install a 2-ton pillar-mounted jib crane with a concrete foundation right next to the station, paired with a two-speed chain hoist. Workers use it instantly, doubling repair efficiency through precise handling.
Case 2: Machining Workshop
- Site Pain Points:Multiple CNC machining centers are lined up with a raw material zone at one end and a finished goods zone at the other. Dozens of heavy metal bars must travel long distances between different machines daily.
- Optimal Solution:Install a 5-ton single girder overhead crane spanning all machines and handling zones. It acts like a “high-speed freight train” in mid-air, completely clearing the logistics artery of the entire production line.
Case 3: Mixed-Demand Workshop
- Site Pain Points:The workshop needs full-floor coverage for assembling heavy equipment, plus high-frequency lifting for local parts grinding. If there is only one overhead crane, workers fight over it daily, destroying productivity.
- Optimal Solution:We strongly recommend a combined solution using both jib and single girder cranes. Run a 10-ton single girder crane above for unloading and heavy chassis transfers. Below, mount several 1-ton wall-mounted jib cranes onto existing pillars next to the grinding stations. The overhead crane handles heavy tasks while workstations manage small jobs independently. The two systems work together seamlessly without interference.

Conclusion
In the end, industrial equipment procurement is not about finding the best numbers on paper. It is about who can clear the real logistics bottlenecks on your floor. Choosing between a jib crane and a single girder overhead crane is a live geometry problem about factory space and a financial calculation about production efficiency.
- If your core pain point is high-frequency local lifting:Workers constantly load and unload materials at fixed machines and need a dedicated “steel soldier” without waiting in line. A jib crane is definitely the best low-cost, high-reward solution.
- If your core pain point is full-area material transfer:Materials must travel dozens of meters through different processes, or your shop frequently handles heavy chassis weighing several or dozens of tons. A three-dimensional single girder overhead crane is the essential “main artery” to boost plant capacity.
Buying the wrong crane costs far more than just the equipment price. It wastes money through hidden downtime daily for years to come. Only by laying out your factory dimensions, headroom, actual loads, and future expansion plans together can you turn this investment into real productivity.

FAQ
We have compiled the key questions clients care about most:
Q1: Low headroom or no corbels? Can I still install a single girder overhead crane?
A: Yes. For low ceilings, we use low-headroom hoists to gain 0.5–1 meter of lifting height. If columns lack load capacity, we can build an independent steel frame, or you can install pillar-mounted jib cranes at core stations.
Q2: Can I fix a jib crane directly to the floor with expansion bolts?
A: Never do this! Except for light loads under 200kg, rotating a loaded crane creates a huge overturning force. This can easily tear up thin factory floors. We provide standard drawings to help you pour a proper concrete foundation.
Q3: For overseas clients, do you provide on-site installation?
A: We offer global turnkey service, but flying a crew out is expensive for small shops. Instead, we provide 3D drawings, wiring videos, and 1-on-1 remote guidance. Hiring a qualified local team is much more cost-effective.
Q4: Very tight budget. Which option is most cost-effective?
A: Fix your biggest bottleneck first. If funds are low, forcing an overhead crane brings high rail costs and low-spec gear. Buying two high-quality jib cranes for your busiest stations solves immediate problems. You can upgrade to a full system later.
