Description

The Weihua BMH electric hoist semi-gantry crane is an economical lifting device launched by Weihua Group for the light material handling market. This product is used in conjunction with wire rope electric hoists of models such as CD1 and MD1, and is a small to medium-sized rail-mounted semi-gantry crane. Its unique semi-gantry structure design—one leg runs along a ground track, and the other runs along a track on the factory's load-bearing beam or wall—makes it particularly suitable for lifting operations within a half-span range, perfectly solving the applicability issues of traditional bridge cranes and full gantry cranes in certain special working conditions.

This product is a general-purpose crane with a lifting capacity ranging from 1 ton to 16 tons, a suitable span of 5 meters to 20 meters, a lifting height of 6 meters to 9 meters, and a working class of A4. It is suitable for working environments from -20℃ to +40℃. The product can be widely used for loading and unloading operations in open-air locations and warehouses, and is also suitable for material handling in indoor environments such as machine shops.

In terms of control methods, the BMH electric hoist semi-gantry crane offers both ground operation and remote control operation, allowing users to flexibly choose according to their working environment and operating habits. With its compact structure, light weight, low cost, easy operation, safety, reliability, and attractive appearance, this machine is an ideal choice for small and medium-sized enterprises to achieve mechanized material handling.

Advantages

When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:

Space-Saving & Cost Efficiency

The innovative semi-gantry design features one end running on an elevated building rail and the other on a ground rail, requiring only one set of support legs and ground-level rails. This reduces structural steel requirements and foundation costs compared to full gantry cranes, while freeing up valuable floor space.

Compact & Optimized Structure

The BMH model adopts a modular and parametric design with a compact single-girder structure and low clearance electric hoist. This results in smaller dimensions, reduced wheel loads, and lower overall weight, which further decreases the required building height and infrastructure investment.

Precision Control & Stable Operation

Equipped with variable frequency drive (VFD) speed regulation and advanced PLC control, the crane delivers smooth, stepless speed control and precise load positioning. Features such as inching movement, dead slow, zero-speed hover, and optional electronic anti-sway technology enable safe, accurate handling even in confined spaces.

Safety-Ready & Flexible Configuration

The crane comes with comprehensive protection devices including overload, zero, and limit protection. It supports multiple control modes—pendant, wireless remote, or cabin operation. Optional smart features like anti-collision, multi-hook synchroniz
