Yes, absolutely. Since lifting machinery requires highly stable power integration, matching the local grid voltage is critical for motor and control system safety. We support comprehensive electric customization, including:
3-Phase Power:
380V/50Hz (Standard for Europe, Mid-East, China), 220V/440V/480V/60Hz (Standard for North/South America), 415V/50Hz (UK/Australia), and 200V/50Hz-60Hz (Japan).
Single-Phase Power: 220V/240V/110V 50Hz/60Hz (Commonly for mini hoists or portable gantry cranes). All our control enclosures utilize premium international brands (e.g., Schneider, Siemens) and undergo strict load testing under your customized voltage parameters before leaving the factory. This customized rating will be clearly engraved on the equipment nameplate.
Safety is our top priority for industrial hoisting machinery. Our equipment strictly complies with international safety and engineering standards:
CE Certification:
All our spider crawler cranes, portable gantry cranes, and electric hoists comply with the EU Machinery Directive (2006/42/EC). We provide official CE certificates to ensure hassle-free customs clearance and local job site permits.
ISO 9001 Alignment:
Our manufacturing alignment is strictly audited under ISO 9001 quality management procedures.
Strict Load Testing:
Each hoist unit is subjected to a 1.25x static load test and 1.1x dynamic load test prior to dispatch. A verified test report with our QC seal is issued with the shipment.
Engineering Deliverables:
We supply comprehensive technical specification sheets, Load Charts, electrical schematic diagrams, and English operation/maintenance manuals with the equipment.
Crane steel structures (such as gantry beams and vertical columns) are bulky, heavy, and highly susceptible to marine salt-spray corrosion. We utilize strict seaworthy heavy-duty packaging protocols:
Rust & Moisture Protection: Precision-machined surfaces are coated with anti-rust grease. The main body is fully vacuum-wrapped with multi-layer high-strength stretch film, moisture-proof bubble wrap, and desiccant packs.
Solid Outer Enclosures:
High-value components and compact equipment (such as spider cranes and hoists) are packed in fumigation-free heavy-duty plywood cases or steel-wood composite crates.
Secure Container Lashing: Inside shipping containers, heavy beams are seated on solid structural steel or timber cradles, secured tightly using wire ropes and turnbuckles anchored to container floor rings. This guarantees zero movement during ocean transit. Precise packing dimensions, gross weights (G.W.), and total volumes (CBM) are calculated upfront during the quotation phase so you can easily estimate LCL or FCL freight budgets.
The choosing between steel and aluminum alloy depends heavily on your workspace environment, portability needs, and load requirements
Yes, the majority of our portable gantry crane models feature a
dual adjustable system (Height and Span):
Height Adjustment:
Telescopic upright columns with equal-interval safety pinholes. Adjustments can be completed via manual hand winches or hydraulic jacks (depending on configuration) to lift/lower the inner telescoping tube, then locking it securely using high-strength safety lock pins.
Span Adjustment:
The column bracket flange clamps can slide along the length of the crossbeam. This allows you to infinitely adjust the spacing width between the two support legs to accommodate varying workstation widths or tight corridors. The adjustment process requires no welding—only basic manual hand tools (such as wrenches) to secure the clamps in place in 5 to 10 minutes.
This is an important logistical factor to calculate during the quotation phase.
Because the crossbeam length (typically ranging from 3.5 to 5 meters) exceeds standard shipping pallets, we optimize logistics by shipping the gantry crane fully disassembled:
LCL (Less than Container Load) Shipping:
Since ocean carriers often apply "Oversized Surcharges" for packages exceeding 3 meters, we engineer highly compact packing solutions. The beam is individually placed in a custom elongated, heavy-duty plywood case, while the legs are folded down. This compact dimensional package (e.g., 350cm * 80cm * 50cm) minimizes total CBM and mitigates excessive freight surcharges.
FCL (Full Container Load) Shipping:
For bulk orders (e.g., 5 units or more), the long beams are laid flat or bracketed along the walls of a 20ft or 40ft container, and the leg structures are nested together. This maximizes container cube utilization and dramatically lowers the unit freight cost. Please share your nearest destination port with us, and we will obtain real-time, competitive sea freight estimates from our cooperative logistics network.
Electric chain hoists and wire rope hoists have distinct engineering characteristics. Choosing between them depends on your budget, lifting tonnage, and workstation dimensions
Our standard industrial electric chain hoists are rated at
FEM 2M / ISO M4 (or M3)
, which means they are designed to handle frequent, high-load industrial lifting cycles for several operational hours daily. Regarding safety architecture, our hoists are equipped with high-standard protective components:
Dual Electromagnetic Brakes:
Instantly lock the lifting mechanism upon loss of power or when the stop button is pressed. The safe, short braking distance ensures the payload never free-falls.
Upper & Lower Limit Switches:
Cut off the motor control circuit automatically when the hook block reaches the maximum elevated or lowered position, preventing chain binding or structural damage.
Mechanical Overload Clutch:
Designed to slip safely when the lifting load exceeds the rated capacity, protecting both the hoist structure and the operator from overload accidents.
IP54/IP55 Protection Rating:
Dust-tight and splash-waterproof enclosure, ensuring robust operation in challenging industrial workshops or outdoor applications.
Selecting the correct crane architecture requires balancing
load requirements, workshop headroom space, and capital budgets
. The differences are detailed below:
Single Girder Overhead Crane:
Structure:
Comprises one main bridge girder and two end carriages. The electric hoist hangs from and travels along the lower flange of the single beam.
Load Parameters:
Ideal for 1 to 20 Tons, with spans under 22.5 meters.
Strengths:
Lighter self-weight, requiring minimal load bearing from your factory columns. Lower initial equipment cost and foundation civil investment, making it perfect for small-to-medium workshops with low-to-medium duty cycles.
Double Girder Overhead Crane:
Structure:
Comprises two parallel main girders. The crab/trolley winch unit sits and travels along rails welded on top of the double beams.
Load Parameters:
Suitable for capacities from 5 to 500+ Tons, accommodating extremely wide spans and heights.
Strengths:
Because the hoist trolley travels on top of the girders, it delivers superior hook vertical headroom (higher lift height). Built for higher duty classes like FEM 2M/3M (ISO A5/A6) for continuous, heavy-duty processing, and supports attachments such as grabs, magnets, and auxiliary hooks.
We have established a mature, highly streamlined
Remote Engineering Assurance Protocol
to support international clients in self-installing our cranes:

All structural splice-joints, electrical wiring terminal strips, and cable harnesses are color-coded and marked with
unique bilingual (English-Chinese) labels
prior to shipping. This modular system allows your local technicians to align matched codes and bolt or plug them together seamlessly, eliminating complex onsite welding.
Engineering Deliverables:
We supply stamped general assembly drawings (CAD), steel structure anchor-bolt foundation plans, detailed electrical schematics, and terminal wiring diagrams.
24/7 Live Video Engineering Consultations:
Our dedicated after-sales engineering team is available round-the-clock. If your onsite crew encounters a technical bottleneck, we can jump on a live video call directly with your crew to troubleshoot and guide them through the alignment or commissioning process in fluent English.
