Jinghe manual single-beam bridge crane is extremely economical: 0 power consumption: purely human-driven, no motor or cable investment, long-term electricity saving; low-cost operation and maintenance: simple structure, maintenance only requires basic lubrication, and the cost of spare parts replacement is extremely low; high cost performance: the price is only 30%-50% of electric cranes, and it is the best choice for light load handling of small and medium-sized enterprises. Flexible and reliable: power-free operation: it can be safely used in workshops without electricity, explosion-proof areas (with explosion-proof hoists), outdoors and temporary construction sites; precise control: the speed of manual push and pull is controllable, and the hoisting positioning accuracy is high, which is particularly suitable for the handling of precision equipment; fast installation: modular design, low load-bearing requirements for the plant, and it can be put into production in 1-2 days. Strong and durable military-grade steel: the main beam is made of cold-rolled high-strength steel, the deformation resistance is increased by 40%, and the service life exceeds 15 years; ultra-low failure rate: mechanical transmission has no complex circuits, and the failure rate is <0.5% (year); full protection design: the wheels are sealed and dustproof, and the track is compatible with I14-I28 I-beams, which are suitable for dusty and humid environments.

Overview

A Manual Single Girder Overhead Crane is a light and small lifting equipment with a simple structure, flexible operation, and economical and practical. It mainly consists of a main beam, end beams at both ends (with running wheels on the end beams), a manual operating mechanism, and a manual or hand chain hoist (as a lifting mechanism). Its core feature is that it is completely driven by manpower and does not require power supply. It is particularly suitable for use in places where there is no power supply, strict explosion-proof requirements, or only intermittent, lightweight material handling is required. It can run forward and backward on a fixed-span track, covering a rectangular working area, effectively improving the material flow efficiency in workshops, warehouses or production lines.

Core structure and working method

Main beam: high-strength I-beam or box beam, bearing core.
End beam and wheels: installed at both ends of the main beam, supporting the crane to be manually pushed and operated on the track in the length direction of the factory (trolley operation).
Lifting mechanism: standard hand chain hoist or hand lever hoist, responsible for lifting and lowering.

Operation mode

Trolley operation: The whole machine is pushed forward and backward along the main track by manpower.
Trolley operation (optional): The hoist is installed on the wheeled trolley and can be pulled by manpower to move left and right under the main beam (in the width direction of the factory building) to achieve precise positioning.
Track: I-beam track, fixed to the factory building support structure.
