Efficiency, durability, and safety comprise the trifecta of characteristics to look for in a portable gantry crane system. These are essential to ensuring your tasks can be accomplished cost-effectively and without unwelcome surprises such as equipment breakdowns, property damage, or worker injuries.
At Wallace Cranes, we engineer our portable gantry cranes for optimal productivity and reliability. But what makes them the more dependable choice over other manufacturers’ crane solutions? Let’s dig into the features and advantages of our cranes’ innovative design.
Self-Centering Beam Support for Safer Handling
Our Tri-Adjustable, Hippolift, and 15-ton gantry cranes are engineered with self-centering beam support to improve stability and decrease setup time. When all casters are in the unlocked position, these cranes are built to automatically center over loads, offering a more stable lifting process than cranes using rigid beam suspension methods. The self-centering beam makes it easier to align and lift loads, minimizing the risks of tipping and reducing strain on critical components such as beams, hooks, and trolleys.
Pinned-Joint Construction for Faster Setup
Gantry cranes featuring pinned-joint construction simplify assembly while ensuring stability. This design allows for joints to be pinned at both ends, reducing stress on the support member and eliminating the need to bend metal to achieve the required fit. Our pinned-joint design allows the crane to distribute loads more evenly and remain flexible, while torsional or off-angle loads are reduced due to the four-bar link design. This means that you’ll reduce manual effort without sacrificing your equipment’s extensive lifespan.
No Welds in Tension for Reliable Performance Under Stress
If a crane’s welded joints are in tension, cracking, breaking, or other failures can occur. Wallace portable gantry cranes are designed to protect joints from impact with critical internal welds that are not subject to tension or impact-prone areas, ensuring structural integrity and dependability. This design principle offers assured reliability and reduced wear and tear on your valuable lifting equipment.
Surer Fit for Efficient, Hassle-Free Assembly
A crane designed with one pin per leg, attaching to a movable beam support bracket, provides a more precise, more secure fit. At Wallace Cranes, we engineer our portable gantry cranes with a cleaner, more repeatable fit-up to reduce the likelihood of assembly-induced stresses and maximize our equipment’s longevity. Each support pin carries one quarter of the load, and can be inserted without forcing perfect alignment, so crews spend less time nudging the structure into place and more time lifting. Less stress on each load-bearing pin means longer crane life and exceptional long-term performance.
Increased Flexibility for Real-World Scenarios
Working on uneven floors? No problem! Our gantry cranes feature a frame and casters that flex, ensuring all four wheels are in contact with the surface at all times. This flexible design is the gold standard for gantries, as it helps the crane stay fully supported on floors that aren’t always perfectly flat. Adaptability on uneven ground provides better stability and enables more even loading. Our cranes’ frame flex also ensures that the load is equally distributed among all the casters. Then, even if the load is entirely on one end of the crane, it will still be evenly distributed between those two legs.
Don’t Settle for a Less-Than-Superior Crane
Stability, ease of setup and use, safety, and versatility are imperative when considering which portable gantry crane will meet your needs and deliver a respectable return on your investment.
