Features

  • Built on frames that are designed and processed using Nitchi's proprietary technology, our end carriages are lightweight and highly durable.
  • Whether top-running or suspension types, the two carriages used in a pair are symmetrical.
  • Holes provided at the center of a frame are used as the standard for processing girder-mounting holes.
  • Suspension end carriages employ a mechanism that prevents wheels from falling off while the load is being lifted or transported. (Not applicable to EL40108.)
  • In addition to standard speed, end carriages are also available in high-speed, half-speed, and dual-speed modes.
  • Silent motorized end carriages employing urethane wheels are also available.
  • Geared-type and plain-type end carriages are also available.
  • The main frame is coated for rust prevention. (The motor is coated with Munsell 8.75R4/14.)
  • Base plates are available as options to be incorporated into your cranes.
  • A wide array of optional peripheral equipment is available including:
    • Crane control box (operating voltage: 24V)
    • Inverter
    • Radio unit
    • Infrared remote controller

    Note: Power on/off device and dual-speed mode are also available.

The maximum wheel load of an end carriage is determined according to its rated load, span, girder mass, and hoist mass. Select the appropriate model by referring to the following tables.

Girder (I-Beam) Dimensions

For making an overhead crane with end carriage, select a girder (I-beam) from the following table.

(e.g.) When your end carriage has a rated load of 2 t and a span of 10 m, select I-400x150x10.
(Although I-350x150x12 can also be used, lightweight I-400x150x10 should be selected.)

(1) Figures in the above table are calculated with the assumption that deflection is limited to one thousandth of a span.
(2) When designing and installing cranes, make calculations based on applicable crane construction standards.

Calculating the Maximum Wheel Load of a Crane

To determine the required strength of a structure or a runway on which the crane is installed, or to calculate the allowable wheel load of an end carriage, the maximum wheel load of a crane must be taken into account. Use the following formula to calculate the maximum wheel load of a crane.

Drop-Prevention Mechanism for Wheels

For easier installation, suspension cranes employ removable wheels. A mechanism prevents wheels from falling off while the crane is being moved or installed. (Not applicable to EL40108.)
