Overview
LD single-beam bridge crane is a lightweight, economical and practical electric lifting equipment with a single main beam structure, suitable for material handling scenarios with small and medium tonnage and medium and low working levels. It has a compact structure and flexible operation. It is widely used in indoor places such as workshops, warehouses, and production lines. It is the main structural component of lifting production.
Structural component of lifting production
Main beam
Adopts box-type structure or I-beam design, with high strength and lightweight characteristics to ensure load stability.
Common off-track design (trolley track deviates from the center of the main beam) optimizes force distribution.
End beam (trolley travel mechanism)
1. Connects both ends of the main beam, equipped with driving wheels and driven wheels, and the drive form is divided into centralized drive (single motor) or separate drive (dual motor).
2. Smooth operation, suitable for straight or curved rails.
Electric hoist
1. Suspended under the main beam, responsible for lifting and horizontal movement (lateral operation).
2. Standard wire rope hoist (such as CD1 type) or chain hoist, tonnage range is usually 1 to 20 tons.
Operation mechanism
1. Trolley operation: The crane moves longitudinally along the factory track as a whole.
2. Trolley operation: The electric hoist moves horizontally along the main beam (some models have fixed hoists and only the main beam moves).
Electrical control system
1. Conventional operations are controlled by a ground button box (moving with the equipment) or a remote control.
2. Contains safety devices such as overload protection, limit switches, and emergency power-off.
