Introduction
The simple gantry crane consists of left and right columns, top crossbeam, electric hoist (or hand chain hoist) and base. The columns and crossbeam are connected via bolts or pins to form a stable portal frame structure. The crossbeam adopts I-beam, the electric hoist moves horizontally along the lower flange of the crossbeam, equipped with the hoisting mechanism to achieve three-dimensional load handling. Fixed models are fixed to the ground via anchor bolts, with large load capacity and good stability; mobile models are equipped with high-strength universal casters (with brakes) at the bottom, can be pushed and moved on flat ground, and lifting can be performed after brake fixation; detachable models adopt modular bolt connection, can be quickly disassembled and transported, suitable for temporary sites and rental use. The product is equipped with a chain electric hoist or wire rope electric hoist, with smooth lifting and simple operation; columns adopt seamless steel pipes or section steel, with good structural rigidity and strong load capacity. The simple gantry crane requires no dedicated workshop and rails, can be installed and used in any flat site indoors and outdoors, especially suitable for light-duty lifting occasions such as workshop mold lifting, warehouse cargo loading/unloading, equipment installation and maintenance, construction site material handling, serving as an economical light-duty lifting device to replace bridge cranes and fixed gantry cranes.
Application
Our Advantage
Simple structure with low cost: Adopting a minimalist portal structure of column + crossbeam, with few parts and easy manufacturing, the whole machine price is only 1/5~1/10 of bridge cranes, with fast return on investment, especially suitable for small and medium enterprises, warehouses and temporary sites with limited budgets.
Mobile/detachable with flexibility and convenience: Mobile models have universal casters at the bottom, one person can push to any work point, lifting can be performed after brake fixation; detachable models adopt bolt modular connection, can be quickly disassembled and transported, not occupying fixed space, especially suitable for temporary sites, rental and occasions requiring frequent work point changes.
Easy installation without foundation: Fixed models only require simple pit or ground expansion bolt fixation, no embedding, no dedicated rails and machine room required; mobile and detachable models require no foundation at all, can be used after assembly on site, short installation cycle, civil construction cost almost zero.
Large load capacity with wide application: Rated load capacity 0.5t~10t optional, span 3~10m and lifting height 3~6m customizable, can carry molds, pallets, equipment and other heavy objects, meeting various light-duty lifting needs such as workshop mold lifting, warehouse loading/unloading, equipment maintenance, construction sites, one device can replace multiple manual handling.
Easy operation with convenient maintenance: Equipped with electric hoist pendant station to centrally control lifting, lowering and traversing, simple and easy to operate; simple structure with universal parts, daily maintenance only requires regular wheel lubrication and connection bolt inspection, low maintenance cost, ordinary workers can complete daily maintenance, long service life of the whole machine.
