LDC Model Low Headroom Single Girder Overhead Crane

Product introduction

LDC model single girder overhead crane belongs to very low clearance light duty lifting equipment, it is composed of girder weld by a steel plate and I-steel, end girder, electric hoist and traveling mechanism. The electric hoist runs along the lower flange of the I-steel of the girder to accomplish article hoisting. It features light structure and easy installation and maintenance and is widely used for different places for hosting, such as factories, warehouses, and material yards. It is prohibited to use in the environment with inflammable, explosive and corrosive media.

LDC Low Headroom Single Girder Overhead Crane is designed for low headroom workshop. The difference between them is the way of electric hoist running. The electric hoist of LDC is running at the bottom flange plate of the girder and the electric of LDA is running at one side of the girder, which increases the workspace of the hook and reduces the workshop height and cost.

If your workshop is narrow or not high enough, please consider choosing this kind of crane!

Features

Light Weight Design:
  • Height: The overall height of the crane can be lower 20%~25% of the tradition crane.
  • Self-weight: The self-weight reduced by 20%~30%.
  • Wheel pressure: The maximum wheel pressure can deduct by 15% ~ 20%.
Modular Design:
  • Each spare parts of the crane can be design to series standard modulus, it can lavish the product combination.
  • Its independent modulus is convenient for the transportation.
  • Standard modulus production, it can ensure stability quality of the product, it can shorten the delivery period.
Advanced Technology:
  • Using the digital cutting machine to cut the web plate, ensure the smooth and precision of the camber curvilinear.
  • Main welding seam adopts auto arc merged welding, Ultrasonic, X-ray nondestructive inspection.
  • The bridge and trolley frame adopts floor type boring machine to ensure the flatness of the machine side.
High Security:
  • The safety supervises system equipped with overload limiter, and on the monitor, it can display the load's value, it can remind the operator to prevent the overload.
  • Before the start, the entire controller will start self-checking, includes power voltage, default phase, the effect of each safety protective device and zero position of the button.
High Reliability:
  • Motor insulation grade is F, and protective grade is IP54, it also has overheated and alarming function, the motor cover adopts aluminum alloy to drawing the molding, with better heat dissipation.
  • Main electric elements adopt the international brands include Schneider, Siemens, ABB. The protective grade of electric control box shall no less than IP54.
