design of hoists

DESIGN, FEATURES & SPECIFICATIONS

Reliability and safety are the most desirable features for an electric wire rope hoist. Hence, we use best quality electric wire rope hoist made using advanced technology. Our electrical hoist wire are suitable for medium and heavy duty operation. The modular construction allows easy accessibility of components for maintenance. Components like rope drum, gear box, motor, brake and panel can be easily attended.

STANDARD FEATURES

DESIGN :- Compact & modular design, low weight, easy to operate and maintain.

MOTORS :- Sturdy cylindrical/conical rotor pole-changing motors (continuous cast aluminium sections), integrated safety brakes (Insulation class F, IP54 protection).

GEAR BOXES :- Precision flat helical/spur gear units in light alloy housings (case-hardened gears), excellent surface treatment and permanent oil/grease lubrication.

BRAKES :- Single/dual-disc electromagnetic DC brakes with advanced features like automatic braking on power failure. Asbetsos free brake linings that can perform 1 million braking operation. Low in maintenance.

ELECTRICAL PANEL :- Modular design, easy to install and maintain, reliable operation, fuse less circuit, ducted wiring and compact terminals. Drives with motor overload protection to prevent overloading.

PAINTING :- Every part of the hoist is thoroughly scrubbed and painted. Before the assembly double coat of the primer is applied and after the final testing the surface coated with twin layer of paint.

ROPE DRIVE :-Compact design and low weight

SUPPORTING STRUCTURE, TROLLEYS AND DRIVE SYSTEMS :- The standard hoist in the chassis can be designed for heavy and medium load applications with different types of traveling gears. Compact design, low height are some of the standard features of the hoist. Further, the articulated end carriage joints ensure that the wheels remain on the track and the load is properly distributed on the complete system.

SPECIAL FEATURES

  • LIMIT SWITCHES :- Prevents over hoisting and lowering of hook.
  • PUSH BUTTON STATIONS :- Light display, handy, simple operation, Aluminium, constructed from extruded section.
  • SOFT STARTS :- Electric/electronic soft start modules connected to the travel drives to achieve jerk free, cushioned & smooth start.
  • MAINTENANCE PLATFORM WITH HAND RAILING :- Simple maintenance of the Crane extended partially or totally along the girder.
